Anyone running this 295/35/18 fronts & 315/35/18 rear combo on their trans am?
If so what particular wheel make -- rim width & offset mm/

I'd run the 30 series...
I'm running 315/30-18 on all 4 corners.

sounds like a good idea but do not want to lower my suspension
i prefer staying stock & having approx 26.6 tire diameter

You can't tell me that those don't rub in the front when you turn... that has got to be a complete nightmare... i have a '95 w/the zr1 wheels... not sure whether 17x9 or 9.5??? but either way... they scrub when i turn the wheel, and back out of my driveway, i can't stand it

245/40/17 tires are on my original factory alumimum polished speedline rims is what is currently on my 2002 WS6.
the offset wether you have a 17--18 or 19" rim is the most important first step when installing a aftermarket rim, Then of course the tire size is the next important factor.
CCwheel or Fikse wheels can tell you exactly what will work on any original trans am,

**hot93rod** · 12-19-2008, 11:25 AM

so how do i find the offset of them when i did not buy these wheels?

**rstewart** · 12-19-2008, 11:29 AM

not sure if it is stamped on the inside of rim ??

i spoke to Fikse a while back & they told me wether i use a 17--18 or 19" rim -- a 38+ offset is what i would need is a 9--11 " wide custom rim from them,
Cost if the reason i cannot purchase from them

Good question, but i do have a set of 15x10, and 15x6? welds available (pics upon request), i haven't done anything w/the car in a long time... lol, and my other car has the 17x9/9.5? zr1s... if you're interested in either, i just want to go back to a thinner 16" wheel... prob factory

i dont think they made a 315/35/18 i use and see all the time 315/30/18

**rstewart** · 12-23-2008, 09:44 AM

you are most likely correct !!
315/30/18 is the most popular rear tire pn a 10.5--11 "
to get the set from same manufacturer with the same tread design using different sizes is a problem,
sure would like to know if anyone is using the 275/40/18 up front on a 2000--2000 T/A ??
