I just bought 4 Firestone Indy 500's 255/60/15. Mounted on chrome 15 x 8 rally wheels.  Bought the wheels from Summit. The tires look good and handle well also. I did not mount them with the white letters out. Just my choice. Give them a check out. I usually run 32psi all around for my hwy cruise drivin'

I chose the exact same tire.  But the white letters out.  I haven't driven it enough yet to determine tire pressure.  I'll give the 32 a try.

The tire info on my door(s) say "for fuel economy", 30 front, 35 rear for both the 255/60s or the 225/70s.  Optional pressures are 20/26 which sounds awful low to me. Maybe for autocross or something like that.   Mike

     You have to watch some tire stores they will generally over-inflate tires to "seat the bead to the rim" then adjust to correct pressures. Sometimes they forget to adjust the pressure. My Goodyears were at 40 psi when I checked them at home after driving less than a mile. Makes for ruff ride and hard to handle. Check tire pressure often. I carry a guage in my vette. I have found that 30 front and 32 rear works best for me. I have Goodyears on the vette now but am going to switch to BFG's and will try same pressures at first and adjust from there. Hope this helps.

Just to be different... (!) My '81 came shod with new
Pirelli Scorpion Zero's when I bought it. Great looking
tyres, and it corners like its on rails

I went with Firestone Indy 500's also. Had BFG's on before that. The BFG's were good, but like the Indy 500's ride and handleing better. I have 255/60x15 and 255/70x15's on factory wheels.
