Tire pressure on a F-150?

So I have a Ford F-150 2wd, and the tire says 80 psi, but the door says 38psi for (manufactured recommendation) what amount should I put in.

Which ford would win in a race?

The 2003 ford f150 or the newer 2004 ford f150 let's say they're both 4x4 and extended cab.

The 2003 model has 260 hp and 350 ft-lbs at 2500 rpms

The 2004 has 300 hp and 365 ft-lbs at 3750 rpms

The 2003 model only weighs about 4800 and the 2004 weighs about 700 pounds more.

I know trucks aren't made for racing but I'm just really curious because I got a 1999 f150 and thinking about getting the new generation.

94 f150 belt will not stay on?

I have a 94 ford lightning with the 5.8 in it, I've change the belt tensioner twice within 1 week, put 3 different belts on it, changed the idler pulley, but after driving it roughly 100 miles the belt will start to work itself off off the harmonic balancer pulley and will cut off the first 2-3 ribs on the belt, I've also just put on another pulley on the harmonic balancer. The other pulleys and accessories are fine, and do not wobble or shake in any way. If anybody could put any input on it that be great thanks
