i am looking for some tires for some 18 x 7.5's and when i look up what seems to be the most popular size tires for 18 inch wheels, 235-40-18, it says they're for 8-9.5 inch wide wheels so i'm wondering if they'll fit or if i need to get a thinner tire or what

 

You can go with 235/40 or 225/40. The wider tire would protect your rim more while the thinner tire may look nicer.

 

i have 235/40/18 tires mounted on my 18x7.5" wheels.. no problems..

 

that's great news, thanks alot guys

 

im actually running on 225/40/18....i only have one curb rash...but thats not even from a curb...

 

Stock, I had 245/45/18...stayed with it when I put on F1's. Rim is 7.5 wide...Id rather have more rubber on the wheels than less. 1FSTMAX are those ROTA Subzero wheels? Im looking into getthing them for my car in gunmetal.

 

225s or 235s

 

225/40, nothing wider.
