Trials Car Tyres are just as important to the performance of the car as in any other form of motor sport. Even though our rules say that they need to be road tyres, and any aggressive pattern is likely not to be approved, the compound and pattern are all important. Front engined cars are allowed to run flat tyres, which is a huge advantage, although this tends to shred them somewhat so a nice tyre is still important.

All trials tyres seem to last for about three seasons, at which time the leading edges wear off - reverse them halfway through the season for better grip.

I'm not too sure whether front tyres matter at all. These 'Highway' retreads are like battery cases and the reason for my choice here was simply the large diameter. At times they have a slight advantage in that they don't sink in the mud too readily.
