68 camaro 18 tire size

[vaderspartsbin]

I just got my car out of the bodyshop and am ready to put wheels and tires on it. I am going with the chrome boss 338 18x8 front 18x9.5 rear what is the best tire size for this. the car will be lowered with the hotchkins leafs and springs.

Hotchkis springs? I would say a 275-285 width, 35-40 height ratio, 18 in the back and a 235-245 width, 40 height, 18 in the front....
