Fig. 3 (a) is the amplification view of the surrounding of circumferential stria 56.Fig. 3 (b), (c) are the cutaway views of circumferential stria 56.Fig. 3 (b) is the A-A ' cutaway view in Fig. 3 (a), and Fig. 3 (c) is the B-B ' cutaway view in Fig. 3 (a).
The 1st connection location 56c and the 2nd connection location 56d is set to along 2 connection locations be connected with circumferential stria 56 separately of adjacent 2 the adjacent adjacent inclined grooves of tire circumference by tipper 58.Now, the sidewall of the both sides of between the 1st connection location 56c and the 2nd connection location 56d, circumferential stria 56 is provided with chamfered section.Chamfered section comprises chamfering 56a, 56b.Being arranged on the chamfering 56a of the sidewall (the 1st sidewall) of a side in this chamfering 56a, 56b, diminishing gradually relative to the chamfer angle θ of tyre surface normal direction (with reference to Fig. 3 (b), (c)) along with advancing from the 1st connection location 56c in above-mentioned 2 connection locations towards the 2nd connection location 56d.On the other hand, chamfering 56b is arranged on the sidewall (2nd sidewall relative with the 1st sidewall) of the opposing party, and along with advancing from the 1st connection location 56c towards the 2nd connection location 56d, chamfer angle θ becomes large gradually.So-called tyre surface normal direction, refers to the direction of the normal of the surface normal relative to fetus face (land portion).
In addition, in the present embodiment, the chamfer angle θ of chamfering 56a diminishes gradually along with advancing from the 1st connection location 56c towards the 2nd connection location 56d, and the chamfer angle θ of chamfering 56b becomes large along with advancing from the 1st connection location 56c towards the 2nd connection location 56d gradually.But also can be that the chamfer angle θ of chamfering 56a becomes large along with advancing from the 1st connection location 56c towards the 2nd connection location 56d gradually, the chamfer angle θ of chamfering 56b diminishes gradually along with advancing from the 1st connection location 56c towards the 2nd connection location 56d.Preferably, the maxim of chamfer angle θ is in the scope of 35 ~ 55 degree, is more preferably the scope being in 40 ~ 50 degree.Preferably, the minimum value of chamfer angle θ is in the scope of 2 ~ 6 degree, is more preferably the scope being in 3 ~ 5 degree.
Like this, be provided with between circumferential stria 56 and circumferential major trough 54 in the tread contour 50 of tipper 58, tipper 58 does not extend towards circumferential major trough 52, between circumferential slot 52 and circumferential stria 56, be provided with the land portion 57 extended in tire circumference, circumferential stria 56 is provided with chamfering 56a, 56b.Thus, tyre surface defect can not be produced in tire production, realize the tread contour of the road-holding property excellence on dry pavement.Below, this point is described.
As mentioned above, in the vulcanization process of tire production, use the mould of opposite opened as sulfuration mould.After sulfuration just terminates, the protuberance of the mould corresponding with circumferential slot 52 of the mould used to make sulfuration forces the mode departed from tire well width direction from circumferential major trough 52, mould is relatively moved relative to tire.Now, because land portion 57 is set to unbroken extension continuously in tire circumference, the block rigidity in land portion 57 is high, even if so the protuberance of above-mentioned mould is wiped rub moving outwardly of land portion 57, also from the past different, and is difficult to produce tyre surface defect.
Although the well width of circumferential stria 56 is than circumferential major trough 52,54 narrow, groove depth is also than circumferential major trough 52,54 shallow, but the part between circumferential stria 56 and circumferential major trough 54, tire circumference is provided with multiple tipper 58 and defines multiple pieces, so block rigidity is little.Therefore, after firm sulfuration, the protuberance of corresponding with circumferential major trough 52 mould is when forcing to depart from from circumferential major trough 52 on well width direction, and the protuberance of the mould corresponding with circumferential stria 56 can be wiped the surface of rubbing the block (land portion) crossed by circumferential stria 56, circumferential major trough 54 and tipper 58 and easily produce tyre surface defect.Therefore, in order to avoid producing tyre surface defect, chamfering 56a, 56b are set in the both sides of circumferential stria 56.In addition, because chamfering 56a, 56b are according to the position in tire circumference, chamfer angle θ changes, so have nothing to do with the position in tire circumference compared to chamfer angle θ and be compared with constant chamfering, increases with the area in the land portion of earth surface.In addition, block rigidity also uprises.Therefore, the road-holding property on dry pavement can improve.
Like this, tread contour 50 can not produce tyre surface defect in tire production, and the road-holding property on dry pavement is excellent.
In addition, after firm sulfuration, the protuberance of corresponding with circumferential major trough 54 mould is when forcing to depart from from circumferential major trough 54 on well width direction, and the protuberance of the mould corresponding with circumferential major trough 54 can wipe the surface in the land portion of rubbing shoulder zone.But close in midway because tire shoulder ear groove 60 is not connected with circumferential major trough 54, so the end near the circumferential major trough 54 of shoulder zone, be formed with the land portion extended continuously in tire circumference, therefore, the block rigidity of this part is high.Therefore, the generation of the tyre surface defect in the land portion of shoulder zone can be suppressed.
In addition, from the viewpoint of in order to avoid producing tyre surface defect, the center on the tire width direction of preferred circumferential stria 56 is arranged on relative to the CL side, roller tire Central Line, center on the tire width direction between circumferential major trough 54 and circumferential major trough 52.
If the center on the tire width direction of circumferential stria 56 is arranged on relative to the center on the tire width direction between circumferential major trough 54 and circumferential major trough 52 by tire shoulder side (outside tire width direction), block rigidity (rigidity in the land portion between circumferential stria 56 and circumferential major trough 54) then between circumferential stria 56 and circumferential major trough 54 reduces, even if so be provided with chamfering 56a, 56b at circumferential stria 56, also easily produce tyre surface defect.
From suppressing the generation of tyre surface defect, improve road-holding property on dry pavement in consider, preferably, when the width along tire width direction in the region between circumferential major trough 52 and circumferential major trough 54 being set to A (with reference to Fig. 2), the center on the tire width direction of circumferential stria 56 is biased to circumferential major trough 52 side (inside tire width direction) from the center the tire width direction in the region between circumferential major trough 54 and circumferential major trough 52 with the scope of 30% ~ 40% of width A.
In addition, from improving road-holding property on dry pavement, suppress tyre surface defect in consider, the maximum width of the width W along tire width direction (with reference to Fig. 3 (b), (c)) of preferred chamfering 56a, 56b is 20 ~ 30% of the width (width on the tire width direction of tread surface in land portion 57) in land portion 57.When 20% of the width in the not enough land portion 57 of the above-mentioned maximum width of chamfering 56a, 56b, the width of chamfering 56a, 56b diminishes, become large with the area in the land portion of earth surface, so road-holding property improves on dry pavement, but, because chamfering width diminishes, so easily produce tyre surface defect.On the other hand, when the above-mentioned maximum width of chamfering 56a, 56b exceedes 30% of the width in land portion 57, be difficult to produce tyre surface defect, but because reduce with the area in the land portion of earth surface, and then block rigidity also reduces, so the road-holding property on dry pavement reduces.
In addition, from improving road-holding property on dry pavement, suppress tyre surface defect in consider, the degree of depth D (with reference to Fig. 3 (a), (b)) of preferred chamfering 56a, 56b is 15 ~ 25% of the groove depth of circumferential major trough 52.When 15% of the groove depth of the not enough circumferential major trough 52 of the degree of depth D of chamfering 56a, 56b, the road-holding property on dry pavement improves, but because chamfering width diminishes, so easily produce tyre surface defect.On the other hand, when the degree of depth D of chamfering 56a, 56b exceedes 25% of the groove depth of circumferential major trough 52, be difficult to produce tyre surface defect, but block rigidity reduces and road-holding property on dry pavement reduces.
In addition, from the viewpoint of making rolling resistance reduce, the breaking elongation of tread-rubber at 100 DEG C of preferred fetus face is 300 ~ 400%.Such tread-rubber is low because of breaking elongation, so be the rubber easily producing tyre surface defect.But, in tread contour 50, between circumferential slot 52 and circumferential slot 54, be provided with land portion 57, circumferential stria 56 and chamfering 56a, 56b, to make to be difficult to produce tyre surface defect, even so breaking elongation is the tread-rubber of 300 ~ 400%, be also difficult to produce tyre surface defect.In addition, breaking elongation (tension fracture elongation rate) measures by the method according to JISK6251.
In addition, in order to reduce rolling resistance, the tan δ of preferred tread-rubber at 60 DEG C is less than 0.18.Therefore, even if when in order to make rolling resistance low tire the tan δ of tread-rubber is set to less than 0.18 and breaking elongation is set to 300 ~ 400%, in the tire of present embodiment, also can be difficult to produce tyre surface defect, improve the road-holding property on dry pavement.In addition, tan δ measures by the method according to JISK5394.Such as, tan δ measures as follows: tread-rubber is cut into the dynamic viscoelastic of the rubber sample of the sheet of preliminary dimension according to JISK6394, use the visoelasticity spectroscope that Toyo Seiki manufacturing company manufactures, be 10% ± 2% in variable elongation aberration rate, under oscillation frequency is the condition determination of 20Hz, measure.The lower limit of the tan δ of tread-rubber is not particularly limited, such as, be 0.10.
Such tread contour 50 can use a pair mould (patrix and counterdie) formed, and a pair mould is formed respectively and clip central tire line and the tread contour that is positioned at both sides.As mentioned above, because to make the mode not producing tyre surface defect after firm sulfuration form tread contour 50, even if so use the mould comprising the opposite opened of patrix and counterdie to be also not easy to produce tyre surface defect at tire.Can be extended along tire circumference near central tire line CL by the burr of the surface of tyre formed when sulfuration and one week form this point, determine it is use the mould comprising the opposite opened of patrix and counterdie and the tire produced.
In addition, the tire of present embodiment can be applied to the tire size that nominal aperture is 135 ~ 285 suitably.Even if make the opposite opened mould comprising patrix and counterdie in the scope of above-mentioned nominal aperture, also can suppress tyre surface defect, improve the road-holding property on dry pavement.So-called nominal aperture, refers to the part of " 175 " when the sidewall of each tire such as shows tire size as " 175/65R14 ".
The groove area ratio of the tread contour 50 of the tire 10 of preferred present embodiment is 25 ~ 40%, is more preferably 28 ~ 32%.

Below, in order to investigate the effect of the tire 10 of present embodiment, carry out tyre surface defect when making various tread contour and the handling and stability experiment on dry pavement to evaluate tire.
The tire size of the tire made is 175/65R14.Tire makes that the breaking elongation be used at 100 DEG C is 360%, tan δ at 60 DEG C is the tread-rubber of 0.18.Breaking elongation is obtained by the tension fracture elongation rate test cutting into the rubber sample of the sheet of preliminary dimension of tread-rubber.Tan δ measures as follows: tread-rubber is cut into the dynamic viscoelastic of the rubber sample of the sheet of preliminary dimension according to JISK6394, use the visoelasticity spectroscope that Toyo Seiki manufacturing company manufactures, be 10% ± 2% in variable elongation aberration rate, under frequency is the condition determination of 20Hz, measure.
About tyre surface defect, carried out the ocular estimate of the tire after firm sulfuration by inspector, according to the quantity of tyre surface defect, the degree of defect, evaluate with " many ", " slightly many ", " medium ", " lacking ", " not having completely " these 5 ranks.In evaluation result, " not having completely ", " lacking ", " medium " are the scopes of the certified products of allowing.
On the other hand, about handling and stability experiment, make 4 tires with identical tread contour, and carry out running test.Tire is assembled in the wheel rim of 14 × 5JJ, fills the air pressure of 230kPa.These 4 tires are installed on the manned vehicle of free air capacity 1.3 liters, travel on dry pavement with moving velocity 60 ~ 120 (km/ hour), and carry out sensory evaluation by driver.Sensory evaluation carries out relative evaluation with past case described later for benchmark (100).Evaluation number is higher, then represent that road-holding property is more excellent.
Specification and the evaluation result of the tire of past case, embodiment 1, comparative example 1 ~ 3 have been shown in following table 1.
Chamfering in table 1 means the 1st chamfering shown in Fig. 3 (a) ~ (c) and the 2nd chamfering.According to the evaluation result shown in table 1, embodiment 1 is compared with past case, and tyre surface defect is few, and the road-holding property on dry pavement improves.On the other hand, from embodiment 1, comparative example 1 ~ 3 relatively, in order to make few, on dry pavement the road-holding property of tyre surface defect improve, needing to arrange chamfering 56a, 56b at circumferential stria 56, and there is the land portion 57 extended continuously along tire circumference.
