ok when i put my T1R`s on a after few months i kerbed one of my wheels and ended up replacing one of the tyres, i couldent get a T1R at short notice and ended up putting a prada spec II to replace it, ive just had the wheels off the car and the prada is in much better condition than the toyos, considering the tyres have been on almost the same lenght of time done practically the same milage had the same abuse on track etc its been a pretty good comparison between them and i know which im going to be going for next and it aint the toyos
