why do my tires look flat but have proper PSI - Third Generation F-Body Message Boards

I have a set of BFG traction T/A's and the left side are less than a year old but the right side is who knows. Does the age of the tire affect how it sits even if they have proper PSI (30) the right sides look like they have a bulge at the bottom

put 32 to 35 in number one. BFG's have a soft sidewall number 2. Its normal as tires gain heat they gain psi and look less flat as they go down the road. Sometimes if you weak the sidewalls by running on them flat the tires will look low and have bumps (probably not in your case) 30 psi is too low though.

The door placard for my IROC 16's calls for 30 pounds, which I run for the sake of comfort.

you'll get better gas mileage with more psi, it might help on quick turns, it won't look as flat, and it's plenty safe up to like 50 psi.

may cause a bumpier ride, but i'd put em at 35 psi. can't hurt to try.

Somewhat off topic but do those tires ride decent? Are they noisy? Looking for new tires to replace my Walmart specials that are driving me crazy.

yeah they ride great and handle great. The car really whips around corners when its dry out. when its wet I try not to take corners to fast because I've felt the back end start to slide out on me before. They arent noisy or anything at highway speed. I was going off the door sticker to which says 30 psi...
