Tire Psi Help

Take it he's running bias ply Interco tires in the 44" flavor?

old 36" Dick Cepek fun countries, bias

He bought them while we were still in high school (rotflmao)

He's got 38" boggers coming for the '79 K30 though

If in doubt... just do the chalk test.

Pointless unless your tires are at exactly 0 degrees of camber.

Well you can get some what close. If your not at 0!

YOU NEVER NEVER NEVER NEVER NEVER NEVER EVER run what the tire says on the sidewall unless you ALWAYS run FULLY LOADED to the tire's maximum capacity.

For these 225/75-16s ThunderbirdJunkie would recommend 35-38 psi.

Anything more you are sacrificing traction and tire life.

When I was young and foolish and had my first car I remember making the same mistake of running at the tire's maximum tire pressure.

I know of the chalk trick but I've never gotten around to trying it. Even though they aren't the stock tires I run my LT245/75R16 AT's at 33 PSI. They haven't yet shown any signs of bad tread wear and handle well.

While on the trails with my Liberty I don't air down simply because I need every inch of ground clearance I can get. Plus it saves me the bother of airing down & up. I have a YJ too with 33" tall tires and lots of ground clearance that I've aired down as low as 10 PSI. Of course I wouldn't drive the YJ at highway speeds at that pressure. The tire's sidewalls would blow out.
