245/45 on 7.5" rim...
yes i tried this on accident....
its a long story but when i picked my car up when it was first
delivered it had the 8.5" in the trunk as a spare and three 7.5"s
on the car...
i did not notice this when the sidewall blew out on one (ill let
you guess which) of my 245/40 continentals after ~17k miles.
same thing happened to the 245/45 falken only more violent.
both tires were close to the wear bars when they died so it was
not like they had not had pretty good useful lives.
i think these would work great for you only for autocross but i
would not recommend them for daily driving. i run 255/40 kuhmo
victorracers all around on the 7.5" and 8.5" wheels. If you are
going to have dedicated race rubber i recommend r tires unless
you want to be in a street tire class...
the falkens were great in the rain for me. less hydroplaning
than the contisports! they did get noisy at the end of their
