I have been tossing the idea around about upgrading my wheels to 18'. I have a 2002 TL-S that has Comptech Sport Springs on it. I do not want to roll my fenders at all and I don't want to rub. I want the wheels to sit flush like the factory wheels do. I would like to know what width I need and what offset to acomplish this. I would like any info that I can get - Thanks

 

I lot of people I've seen on the forum go with +45 offset. That seems to be the major factor when purchasing rims (at least for 18's). I'm assuming you'll be doing wheels as well as tires. 225/40/18 should be a safe bet.

^^ read that thread...i did and learned that +45 would be alright... depending on how low u go.

 

235/40/18 is fine, thats what i have with my enkei rs-6 rims. but dont go wider than a 7.5 inch rim because you will have the rims and tires sticking out too much. good luck

 

Not true. 8" wheels will fit just fine with the proper offset (+50)
