Found the Goodyears to be a good all rounder, but have 215/40/17 Toyo T1-s's now and notice a lot more grip from them, the only compramise is they don't last as long! Drove both Mine and Mangolds, almost identical cars, at Santa Pod last year, only difference being the tyres. Mangold= Goodyear's Six Appeals + Toyo's Both agreed the Toyo's had lots more accelerating grip, needless to say when Mangold ordered his new rims, he also ordered the Toyo's.
