Miro 111's
 

Finally got around to installing the new wheels/tires on my firebird. I love the look of these wheels, that with the strano springs and koni yellows, looks like a totally different car. Wheels are 18x9.5 around with 275 tires with good clearance everywhere.

Looks Great.

What backspacing? 40?
Also, I don't see a Miro 111 with a 5x120.65 bolt pattern so I'm guessing these are 5x120?

Closest I can find is:
18x9.5, +40mm Offset, 72.6mm bore

The 4th-gen F-body has a 70.3mm hub bore. Did you use a hub-centric ring?

What Size Tire?
275/35R18?

Yes please details looks awesome

Yea they're 5x120. I'm using hub-centric rings from usa wheel adapters, 72.6mm to 70.3mm. They're 40mm offest, and yea the tires are 275/35/18. My 9 inch is narrowed 1/2 an inch so it sucked them in, in the back a bit.

Great. Thanks for the info. :cheers:
