Tires for 18x8, 4.5" BS, 1st gen

[Josh69]

For my '69 Firebird, I was only able to get my hands on some 18x8's to match my rears with 4.5" BS....without waiting 16 weeks to get a different offset.

I'm going to do the Gulstrand mod and some tubular upper control arms. The car has 2" Drop Hotchkis BBC springs (car has a Pontiac motor), with Koni shocks, and Wilwood 12.2's with 6 pistons. I plan to run around 5-6* +caster, and reasonable negative camber, between .5-1*....whatever I can get away with and not wear the tires too quickly.

Can I safely run a 235 or do I need to really consider a 225?

I,ve got a 67 with 18x8 with 4.5 bs and have 255/35 . might be able to go a little taller but i doubt much wider. It depends if you are really trying to tuck them in the wells.

I should have clarified, this is for the front wheels, thanks!
