I tried searching but could not come up with anything. Can you mount a 245/40-18 on a 18x8 wheel?

 

whats stock 225/45?

 

235/45-18, I'm really bad at this wheel tire thing.

 

hmm... 10 more MM... it might fit... hold up im gonna try searching this... im sure someone either has this or has done it

 

i think you can mount it, but here's the factory sizes for 18's:

225/45/18 front
245/45/18 rear

i would do this if i was going to swapout the tires:

225/45/18 front (add 15mm offset spacer)
255/45/18 rear (add 5mm offset spacer)

 

yes it'll fit

 

Most of them will fit with no issues, but look up the specs of the specific tires you want at www.tirerack.com

see http://www.tirerack.com/tires/tirete...p#measrimwidth

to interpret the specs

 

MrBig it would help if you specified if you have SEDAN or COUPE!

245/40-18 should fit on 18x8. it fits perfectly on 18x8.5, and an extra half an inch should not make that much of a difference.

 

Your right! Sorry I usually post in the Sedan thread. The reason I want 18x8 is because I found a set of wheels that I really like, and they only come 8" for the 18" wheel. I want to stay 18" because I do autoX and I want less wheel mass spinning. Thanks for the help.
