Jetko’s range of 1/8th tyre designs covers most of the needs for off-road drivers with only a few styles making your tyre choice simple. This will never change!However, when it comes to fighting for victory at high-level competitions and winning titles, you need a tyre for every special condition.To achieve this level of high performance, the first of these high competition tyres was born…. the “J-Zero”Jetko is a tyre manufacturer with years of experience, their own manufacturing capacity and ready to adapt as track surfaces evolve. To design the NEW “J-Zero” Jetko's engineers looked at the best of the best and analysed how the most efficient tyres performed on low grip tracks. Hours of testing were carried out, mostly on the best European tracks, to understand how our competitors tyres work. It soon became apparent that the challenge was to achieve an extremely flexible tread by creating numerous deformation zones and avoiding designs that offered too much stifness.At the same time, the sidewalls were redesigned to achieve controlled flex. This means that the lugs are slit to ensure that they do not interfere with the deformation of the carcass, and spaced areas multiply the deformation zones.The internal structure of the tyre is also new to prevent centrifugal force deforming the contact patch, improving tyre consistency.Without a miracle the design looks alike the most efficient tyres 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 dry tracks on low grip with traditional rubber.
