What 18" tyres on a classic???
 

Currently running Falken 215/35/18 452's on my classic. Not happy with the level of grip they give, as in the wet the are losing traction on low boost at 300bhp. Looking to change to track day tyres, but can't find in that profile? Nearest I can find is 225/40?

2153518 is the norm but if you roll the arches etc you can get 225,40,18s in there
