rim question
 

hey, im deadset on AR Thrust II's, but im clueless on what the specs are on my 4th gen z28..


i want to run my 245/50/17's up front, but i want to run a bigger width in the rear, 10 / 10.5 in the rear, what size rim should i buy and can somebody please explain to me the whole idea of the backspacing and what it is on my car...



edit: and i didnt notice their was a wheel and tire section, sorry :/ forum n00b

The backspacing depends on what you want it to look like. And you should run a 10.5 if you want to run 315's on the rear. What choices do they give you in backspacing?

NOTE: As far as I know, the biggest you can run without modifying the front is a 275.

well they have alot of different wheel styles for TT2's

but i went and searched my car on the site and it came up with these specs for the TT2's

Product Number: VN50579563
Size: 17x9.5
Product Description: Fully polished
Backside Spacing (in/mm): 7/178
Offset: 45.72mm

Recommended accessories
Center Caps:
Included

Now, what is the max size tire i can run with the 17x9.5?

275/45/17 front and rear.

can i run a 245/50/17 on this rim aswell? and run 275/45's on the rear, or do you suggest i go bigger?


edit, i found this size TT2 for the car for the rear,

part #
505-71163

size
17x11

offset
45

backsize
7 3/4

bolt circle
5-4 3/4

for 93-on Camaro/Firebird


is backsize the same as backspacing, i want the rears to have a decent size lip on them..

You wont be able to run 17x11's in the front. You'll have to stagger the wheel size, meaning using two 17x11's for the rear and two 17x9.5's in the front. A 245/50 wont fit on an 11 inch rim.

Alot of people including myself use this combo :

17X10.5 or 17 X 11 Rear
45 mm offset
5 X 4.75 Bolt Pattern
315/35/17 Rear Tire


17 X 9 or 17 X 9.5 Front
44 mm offset
5 X 4.75 Bolt Pattern
275/40/17 Front Tire

a 245-50-17 is a tall tire to run on the front of an fbody. a 245-45-17 would fit better, or a 275-40-17. for the rear, i would suggest a 275-40-17 as well or 315-35-17 if you plan to run an 11" wide wheel back there.

i currently have 245/50/17s on the stock rims all around my car now, and everything is fine.

thanks all for the help ill keep you posted. im going with the 17x9.5 front and the 17x11 rear

edit: went out and checked my fronts, 245/50/16s

so did u get new tires
