Salut,
à la recherche du meilleur rapport qualité prix pour un pneu destiné au circuit, je suis tombé là dessus.
Les temps au tour donnent une info intéressante :
Hi everyone, the current issue of MOTOR magazine has done another tyre test, this time also with some semi-slicks! Woohoo!
This might help to settle a few arguments here or at least help people who are shopping for tyres.
Test car was the a Renaultsport Clio 197, size tested was 215/45 R17. Driver was Warren Luff.
Past discussion in tyre tests is that generally results can be extrapolated from smaller to large cars, FF to FR, etc. The magazine do acknowledge that fiddling with pressures etc might alter the results.
Road tyres were tested at 35 PSI, semis at 30 PSI, and the slick at 25 PSI (I'm assuming these were cold pressures). Single warm-up lap for road tyres, two for the semis, and 2 or 3 timed flying laps for the lap time.
Lap times are from Oran Park North Circuit (900m).
If you throw a "bang for your bucks" type calculation in, the Maxxis wins the the Road category (Federal 2nd), and the Dunlop still wins the Semi category (the Federal jumps to 2nd).
Obviously take their prices with a grain of salt...
