Post 11 second small block combos

Correct - they are bias ply. They are the heavier sidewall ones as I didn't want to cut it close on weight capacity. No clue on car weight - guesstimate is 3300 with me in it. Tires are too new to have any real wear. Tires are rated for 60 psi - I run 55. Until I get suspension settings correct, I know I can't expect it to handle properly. Thx for the input!
