Conventional tires do not have anti-splashing projections, so if the water in a puddle splashes outside when driving on a rainy road or a road with dirt, it may cause damage to pedestrians traveling along the edge of the road, or view other adjacent vehicles traveling in the same or opposite direction. There is a problem that a safety accident occurs by covering the angular range α <45, δ≥60 shown in the published US 6460584 B1 claim, and the water splash prevention projection is limited to smaller than the maximum cross-sectional width SW of the tire. Therefore, there was a problem that the splashing prevention effect is very small.

The present invention for solving this problem relates to a pneumatic radial tire (1) for passenger cars, SUV (4X4), light trucks, truck buses provided with anti-splashing projections, and more specifically, sidewall (4) In a pneumatic radial tire for a passenger car, an SUV (4X4), a light truck, and a truck bus, including a tread 2 and two or more belts 3 stacked inside the tread, as shown in FIG. Similarly, the water splashing prevention protrusion 5 protrudes along the edge of the sidewall at a position apart from the end of the tire diameter OD. As shown in Fig. 1, the protruding shape has a straight line shape in the traveling direction. As shown in Fig. 2, the protruding shape has a sinusoidal shape in the traveling direction. As shown in Fig. 3, the protruding shape has a sinusoidal shape in the radial direction. Form a splash protection protrusion.

In general, for passenger cars, SUVs (4X4), light trucks, truck buses, not only dry roads, but also wet roads, rain roads, and snow roads in some cases.

According to the present invention as described above, when running on a paved / unpaved road in the rain, it is possible to prevent the water in the puddle of the road to splash upwards to prevent the water from splashing to the upper body of the pedestrian passing through the edge of the road. For passenger cars, SUVs (4X4), light trucks, truck buses, which are provided with splashing prevention projections, which can prevent the accidents caused by preventing the view of other vehicles traveling in the same or opposite directions. It relates to a pneumatic radial tire.

The pavement / unpaved road is a road surface is uneven or a plurality of puddles are formed, when rain rains a lot of rain on the road to form a puddle, when the vehicle is running on the road formed the puddle, The water will splash outwards.

As described above, when the water of the puddle splashes outward, there is a problem that a safety accident occurs due to damage to a pedestrian moving along the edge of the road, or obscuring the field of view of other adjacent vehicles traveling in the same or opposite directions.

Therefore, the present invention is designed to solve the above problems, by forming a water splashing protrusion along the edge of the tire sidewall to prevent water from splashing upwards when running on rainy roads or roads with the water, so that the water Passenger cars with splashing prevention projections, which can prevent splashing to the upper body of pedestrians passing by the edges of the pedestrians, and prevent safety accidents by preventing the vision of other vehicles traveling in the same or opposite directions. It is an object to provide pneumatic radial tires for heavy duty, SUV (4X4), light trucks and truck buses.

In the present invention for achieving the above object, in the pneumatic radial tire for passenger cars, SUV (4X4), light trucks, truck buses comprising a sidewall and a tread, two or more belts are laminated inside the tread, As shown in FIG. 1, the anti-splashing protrusion 5 protrudes along the edge of the side wall at a position h apart from the end of the tire diameter OD.

At this time, the position h of the water splash prevention protrusion 5 should satisfy the following equation.

              10mm ≤ h ≤ 100mm

If h is smaller than 10 mm, the splash prevention protrusion (5) will not rub against the road surface and wear out, and the splash prevention effect (5) may not be effective. It will be far away and will not be able to prevent splashing.

In addition, when the width of the water splash prevention projection is W as shown in Fig. 1, the following equation must be satisfied.

                           5mm ≤ W ≤ 60mm

If W is smaller than 5mm, the width of splash prevention protrusion is small, so that splashing prevention effect cannot be exerted. If W is larger than 60mm, friction and abrasion may not be achieved due to friction or wear by road or obstacle during driving. .

In addition, when the angle of the water splash prevention projections as shown in Figure 1 a, b, respectively, the following equation must be satisfied.

             -60 degrees ≤ a, b ≤ 60 degrees

If the angle of a, b is smaller than -60 degrees or larger than 60 degrees, the splash preventing protrusion 5 is in line with the sidewall line during road driving, and thus the splash preventing effect cannot be exerted.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. As shown in Fig. 1, the protruding shape has a straight line shape in the traveling direction. As shown in Fig. 2, the protruding shape has a sinusoidal shape in the traveling direction. As shown in Fig. 3, the protruding shape has a sinusoidal shape in the radial direction. Form a splash protection protrusion. Figure 4 is a view showing an embodiment of a pneumatic radial tire of the present invention with an anti-splash projection according to the present invention, Figure 5 is an example of a bone provided with a real anti-splash projection according to the present invention It is a figure which shows the actual test result of the pneumatic radial tire of this invention.

According to the pneumatic radial tires for passenger cars, SUVs (4X4), light trucks, and truck buses provided with anti-splashing protrusions according to the present invention as described above, water on the roads on the paved / unpaved roads on rainy roads is on the upper side. Can prevent the water from splashing to the upper body of the pedestrians passing by the edge of the road, and prevents the accident of safety by preventing obstruction of the view of other vehicles traveling in the same or opposite direction It is a very useful and effective invention that makes it possible.
