I am planning to put a new set of rims on my 99 trans am ws6 with 18x9.5 with a offset of 53 and 19x11's in the rear with an offset of 73. they are vette rims, has anyone had issues with these types of rims on the f body and how do i figure which tires wouldn't make my trans am look all uneven and bad looking? any ideas or advice?

I'm pretty sure they won't fit. There's a lot of threads asking if the new oem z06 wheels will fit just do a seach

IMO, Stick with 18's or 19's, both front and rear it'll look better!

Is the only reason u say that based solely on looks 99Bluz28?

they are 19" though, 19x11. i did research on here but don't see anyone with these rims. most people have 19x10 or smaller. You don't think they'll fit though?

Yeah, mainly because a lot people end(not all)end up putting tire on the front wheels with taller sidewalls then the tires on the rear wheels, and IMO It doesn't look good at all!

With 25mm(1") hubspacers the 19 x 11 will fit.

so how do you calculate the correct tire to put on the rims so it doesn't look bad and all?

i have seen a set of 19in rear c6 wheels on a ta with a spacer it looked good.

For example: 275/35/18 tire size, to get the sidewall height take 275 x .35 =

96.25 mm.

For the rear we'll try 315/30/19, 315 x .3 = 94.5 mm

Since 96.25 is really close to 94.5 , a difference of 1.75mm, which is close enough to not be noticable.

Ideally you want the sidewall height the same front and rear, or a little taller in the back to look good.

If it's not, keep the difference down to .125" or 3.1 mm of the front sidewall being taller then the rear tire sidewall.

To convert those numbers to inches divide them by 25.4.

Front tire:96.25mm = 3.79"
Rear tire:94.5mm = 3.72"
