I have 44's on my chevy 4x4. What psi should I run for street use. I have about 15psi in them now. Thing is at somewhat a slow speed the truck bounces. At higher speeds it's smooth. Could it just be a bad balance?

It's mostly because they're huge, much like a balloon. They're probably a Load Range C, normal for most light truck tires, and they give quite a bit. Also, I'll bet they're not rated for very much pressure, again, letting them give and thus: bouncing.

It's just the nature of the tire, nothing out of the ordinary for a 44 :rolleyes:

That is what i was thinking to. Being huge and like a balloon. Thanks for the input.
 
On a full size truck I'd run more PSI than 15. put it up around 30 and see what that does. add or remove air to adjust ride quality and wear. just don't go too much more than what the side of the tire says
 
Taken from JP magazine.

Make a chalk line all the way across the tire, and only drive a few yards. If the chalk line rubs off in the center your pressure is too high. If the edges of the chalk line rub off first, try adding some air. This should extend the life of your tires and keep you from rounding off the edges, or flattening the middle prematurely.

two words: "pad balance"
I have run several sets of 40 to 44's. For them to give the best ride and handleing possible for a tire that size nothing beats proper balancing by way of weighted pads inside the tire. Galloways 4WD in Richfield has years of experience doing this, other 4x4/tire shops may as well. Not cheap but worth it to me for a rig that sees a lot of time on the street.
 
Thanks for the good info. I'll try the chalk line and look into the weights
