So far i've tried the following tyres on the golf:
Bridgestone Re050a, awful tyre, zero grip and the deform while standing still
Toyo R1R, excellent track/road tyre loads of grip even in the wet, don't last so long though
Toyo R888 excellent track tye, awful road manners
On the Touran we currently have Mich PS3, and i find it to be an excellent roadtyre, i haven't had the touran on track,,,, yet
Michelin Pilot Super Sport, excellent track tyre/excellent road tyre, as stated before they are a league above Mich Ps2-3, Goodyear F1 asym, and equivalent tyres, those tyres are very good indeed but the PSS is above the rest due to the use of Twaron and dual compound
