what's a good offset for 18s on the tc???

How wide of an 18" wheel? Are you lowered?

Yeah, there are a lot of factors to consider.

...shoot, I'd say the factors that captainlaziness mentioned are more important than the diameter, lol

i agree that width + offset are more important...

i;ve seen 20's that dont rub on stech's lol

whats the width of the wheel

sorry about not being too specific guys... i'm just in the process of buyin' new rims and tires... i plan to drop my car later with some SS teins later... as for width i'm lookin' @ either 7.5 or 8... thank for all the help...

id go 35 offset on 8" width

40 on 7.5"

I'd do 35 offset with a 7.5" width.

im running 18x8's with a 35 ofset i dont rub however im on TRD's, so he might rub if he's gonna go with SS teins

If you are looking for how a particular width and offset of a wheel will affect (look) on you TC just use this calculator HERE (http://www.1010tires.com/WheelOffsetCalculator.asp).
To use it just type in the factory dimensions (17 x 7 +45) and then type in the dimensions of the wheels that you are interested in...Ex....18 x 8 +38 (mine :lalala: ) then hit calculate. This will show you the change the wheel will do for both inner and outer lip (clearance).
Hope this helps

One other thing to think about is the tire size you choose, if you run a 245-45-18 it will be closer to rubbing with a 2 inch drop then if you run a 215-35-18
