no those wheels will not fit. our trucks have a bolt pattern of 6 x 5.0" not 5.5" also calipers are too big for 15" need 16" minimum.

Hi all, I need to know if I can make these fit.

Summit Racing SUM-85-5883 - Summit Racing® 85 Black 8 Series Wheels - Overview - SummitRacing.com

I drive a 2005 Trailblazer LS 4x4

15" x 8", 6 x 5.5" Bolt Pattern, 3.75" Backspacing

Summit Racing is having a great sale on these, and it's the wheel I've always wanted to put on the T-Blaze.

You might get the 3.75 inch backspacing to work. 3.5 is safer and requires 1.5 inch adaptors to clear.

I have a thread on the reseach and testing I did for 15 inch wheels.

15" rims without proper backspacing and adapters will not fit, but I dont know of anyone that makes 15" rims with our bolt pattern so you'd have to run a spacer/adapter anyway. :thumbsup:

I knew I would have to run adapters, I just don't know anything about backspacing or anything, so I asked the experts! Haha.


Who sells adapters that would work? Also, will I need a spacer kit to lift it a little?

The liftmeister (markmc) sells spacers.

You don't need a lift to change the tire->upper ball joint relationship. Actually, a lift cannot change that relationship.

You do need a lift if you're fitting bigger tires and are hitting the fender or wheel well liner and want that to stop. Or need more ground clearance.

Alright, great! How can I figure out what size tire is best for this configuration? I want something with a mildly aggressive tread, nothing crazy!
