for 235/40/18 it depends on how wide your tire is.Deus Ex Machina said:How would 18" rims with tire size 235/40R18 look on a '99 Marquis? A friend of mine has a set he's willing to let go. I measured the tire height at 26"
For me I have 17x8 in wheels and I use 225 width tires and its pretty perfect. So iit depends on the wheel width
