I have 31 10.50 procomp x terran tires an want to know the right psi for highway driveing I have 30 in them now but they seem low. It says 50 psi with a full load on the tire but thats it. The sides of the tires are getting chewed up pretty bad also.

 

40psi is what i run in mine on the highway

 

Thanks man an sorry about that question LOL.

 

is it snowy where you are? i run about 30 psi in the snow here in colorado.

 

I'd say run more especially if both sides of each tire are wearing.

You can also do things like put some chalk on the ground and drive over it. If the tires are too hard you won't have chalk evenly distributed on the tread. I'm not sure how that will look if they are too low though.

Don't put chalk on the ground put it on the tires, then drive straight for 2-3 tire revolutions. If it wears off the centre the pressure is too high, if it wears off the edges the pressure is too low.

 

i run my tires usually at 35 or so, but with higher pressures your gas milage will go up. but if the sides are wearing then your running too low of pressure. if you notice the center wearing faster than the ouside then its too high.

 

right about chalk the tires, but your results will vary depending on your alignment. all things the same you can see where the tire wears the most. but if all the tires are at same psi and different wear patterns from the chalk, then uneven wear is occuring due to something.

higher psi yields higher mps and rougher ride harder on susp, and going too high compromises traction.
lower psi gives less mps, softer ride and softer on susp.
there is a balance and going towards the extremes is not good.

and i dont necessarily think your question is dumb. reading peoples' setups and locations and mileages helps me determine whats best for my situations.

 

Wow thanks for not getting on me for the dumb question an thanks for the info. I will run 40 psi untill on the beach or snow then 20psi or lower thanks again guys.

 

no problem.....just dont ask that on pirate...

 

the only 'dumb' question is, the question not asked.

no such thing as stupid questions, just stupid people. . j/p, id answer it, but it has already been answered. not a dumb question

 

For best mileage, run as high as you can!
