So I really like these Black Rock Series 900 Viper wheels. I think they could look killer on my Bright Silver Metallic '03 TJ, but I'm not 100% sure they'll fit. I currently have the stock Gambler wheels which I believe are 15x8 with a 5x4.5

They offer the Series 900 wheel in those specs, but I'm unsure about offset and backspacing issues. Anybody know anything about these wheels and if they'll fit on TJs?

Yes 15x8 with a 5x4.5" bolt pattern is correct.

Forget you ever heard the term 'offset' which is a more useful dimension for cars but not very useful at all for Jeeps and trucks. Backspacing is the only dimension to be concerned with. The correct backspace amount depends on the tire width. What size tires do you plan to install on them? Will you ever get to a 33x12.50 or 35x12.50 tire on those wheels?

Backspacing is the distance between the wheel's mounting surface that touches the brake hat or drum, and the inner most edge of the wheel closest to the suspension. The yellow tape measure is measuring the backspace dimension in the first image below.

Offset is the distance between the wheel's mounting surface that touches the brake hat or drum, and the center point between the two tire mounting edges. As in the last image below.

If you plan on going with 32x11.5 or 33x12.5 size tire, go with the wheel with a 3.75in of BS.
BTW, I love the look of those wheels.

Thanks so much for all of that great info. I believe the backspacing on these wheels is 3 3/4" so it really sounds like they'll work. Here's how they'd look on a silver Wrangler. They're not popping like I thought they would. Opinions?

I ran them in 15's on my JK. Nice looking wheel but I needed bigger.
Honestly pics never did them justice. They look so much better in person.
Yeah, I can imagine that. I'm betting that wheel looks even better in a 17x8, too.

What size tires will you be mounting on it and what is the biggest size tire you may get to? And do you air down to go offroading?
Whatever wheel I wind up going with, I'm sure it'll just be 15x8 to save a little money. Also I'm trying to find something that I can just put with my existing 31x10.5 Wrangler Duratracs. They still have some life on them.
