Hey guys long time no post. I've been in the market for new tires and wheels for a while to replace the 16" snowflakes on my 2000 NBM Camaro. I've been looking at getting 17X9 Anthracite TTMs with 275/40/17 rubber. However, recently I've been pricing the polished aluminum TT2.1s and if I go with a 17x8 wheel I can get a good deal on 245/45/17 rubber making the 17x8 TT2.1 wheel/tire combo the same price as the 17x9 TTM combo.

My question is, if I go with a 17x8 wheel what would be the proper wheel offset and backspacing?

 

Depends on what is offered by the manufacturer. Doubt you have any options on offset with AR wheels. Because it is only an 8" rim, you should be able to run up to a 56mm offset.
