Discount tire direct and tirerack both show that this size tire will fit on all four corners with 18x8 wheels and a +40 offset. Anyone running this size tire on this size wheel already on their sedan? Don't want any rubbing issues....and of course, I want the asthetic appeal also. I'd like to run 235/45-18s, but selection is very limited and I live in CO, so I need an allseason tire even when I don't have the Blizzacks on the car. Thanks

 

Aren't people running the coupe wheels on the sedan no problem? Those are 18x8" +30mm offset. I heard the optimum offset is +38mm on the sedan, so you are probably good to go...

 

Thats the exact tire size and wheel size, offsets combo that I am going with
After talking to a few suspension and wheels gurus around here, they all say its good and wont rub for sure even after lowering but the wheels would look a bit TUGGED IN.
G35sedan has 245/40R18 with 18x8 +40 Enkei RPM2 on his ride, it is good, so there shouldnt be any problem

 

I like the look of the lower profile 245/40-18 tires and there are more tire choices. How is the ride on the 40 series tires? Rough? I am used to running on the 235/50-17 tires right now. Also, with the 245/40-18 being 2.3% off OD from stock....Do you have any issues with VDC system?

 

I am running 245/45-18 nitto 555 on Axis supermesh 18" offset 40 all around with HKS LS+ coilover lower about 1 inch front and back on my sedan. Fit perfectly.
