I am going to order some new rims for my car, and I know I want 18x10
deep dish rims in the back, probably 18x9s in the front. I need to
figure out what size tires to fit on these rims to run properly. I was
thinking a 285 or 295 on the back, I know diff manufacturers tires will
have diff treadwidths with the same 285mm rating for instance. Right
now I have 17x9s on the back with P275/40/ZR17 nitto 555s and they
bulge out a bit. I've been doing alot of reading about roadracing type
setups and everything tells me to not have a treadwidth wider than the
rim width, being as 10inches = 254mm I can't see how the rating on the
sidewall could be exactly equal to the treadwidth, so I'm going to have
to get a ballpark and lookup specs on the manufacturers sites. I've
been looking at toyo T1Rs, and nitto. Any one with similiar rims have
any advice? These are on a 1995 mustang GT, lowered w/ FMS C springs,
couple other mods nothing pertinent to this question though.

I would guess that the tire shop (a real one, not quickie auto parts or
Kmart) might have the best answer for you.

If you look at the specs for the tires you are interested in...they will
list the min/max rim width required...
