Set of 4 tires only, to glue

To design the NEW "J-Zero", Jetko engineers studied the best of the best and analyzed the performance of the most efficient tires on low grip tracks.

Hours of testing were conducted, primarily on the best European tracks, to understand how our competitors' tires performed.

It quickly became apparent that the challenge was to achieve a highly flexible tread by creating many deformation zones and avoiding designs that offered too much rigidity. 

At the same time, the sidewalls were redesigned to achieve controlled deflection. This means that the sidewalls are slit to avoid interfering with carcass deformation and that spaced zones multiply the deformation zones. 

The internal structure of the tire is also new to prevent ballooning from deforming the contact patch with the ground, which improves the consistency of the tire. 

Without a miracle, the design looks like the most effective tires on these surfaces, with a sculpted sidewall, wide side blocks that contribute to precision, split diamond lugs and diamond lug blocks. 

The J-Zero will be perfect on wet tracks with cold, wet rubber or on dry, low-grip tracks with traditional rubber.
