ive searched cant find but will a 225/40/18 race tire fit on an 18x8 rim?
and two will it rub at all?

 

why would you think the proper section to post this in is the autocross/road racing section?

 

because the tires are for me to autocross with i just am confused with sizing
i need a race tire that will fit an 18x8 rim and not rub fender well

 

makes sense now. the more details the better. i'll leave it here then. good luck w/ your question.

Will a 225/40 18 fit a 18x8 rim.... YES


Will it rub? Well are you lowered? If so how much?

I would have to guess NOT likely unless you are on coilovers dropped about as low as possible!

 

not lowered at all but would being lowered on springs rub? sportlines?

I run both 245/35/18s and 245/40/18s, both on stock rims. The 35s don't rub at all on the fender, the fender liner or the strut. The 40s sometimes rub the strut in very hard corners.

Many folks run 255s, but those require a spacer to avoid rubbing the strut.

All the above info is for stock springs.
