CM 63 tire air pressure
63 has 205/75/R15s all around. What air pressure should I use for a smooth/comfortable ride? Front springs are big block replacements and rear spring is fiberglass. Suspected a better ride. Current air pressure is 30 lbs. Info on tire just states max air pressure. Thanks, Ed

While I don't have your car, 30-32 sounds like a good start in the front, maybe 28-30 in the rear. Seems most of us have C5s &6s.

That's where I would start, and then take tread wear readings in 3 different places from the outside to inside tread on each tire about every 1000 miles to determine tread wear pattern.

I started at 30 lbs ea. Ride is too rough. Will decrease pressure in 2 lb increments until ride improves. Thanks to all for their assistamce. Special thanks for the tread wear info. This I'll do. Ed
