My wife just bought a 1995 Camaro Z28.
It came with 275/40/17 Tires.
On the sidewall it says "Max Pressure 51 LBS".
All the tires were at about 35 LBS, so I put them all up to abot 40 LBS each.

I'm "Old School" and am familiar with the standard 32 PSI Max in a passenger car tire.
So when I saw 51 LBS I got a little spooked.

Any info/opinions would be welcome.

u go by what the doorjam says. it should say sumthin like 35 for high speed and 30 regular

 

I normally would agree with that, but these are aftermarket Tires/Wheels, so I don't think the "standard" OEM pressures would apply, since those are 16" with a different aspect ratio/size.
These are 17" and are 40 series.
