Hey guys,
Got a bunch of miles on my grizz, Decided to check the air pressures in the tires, they looked over inflated. Turns out, the 2 backs were at 11+psi, and the fronts were at 3.5 Now, The reccomended pressure is 4.3 for the back, and 5 for the fronts. I aired out the backs to 5 and left the fronts at 3.5, Just unloading it from the back of the truck, I noticed a HUGE difference. Is it a bad thing to run them a little high? I really like the stiffer ride. Any suggestions?

If your back can stand it, then it probably won't be bad to run a little higher pressure. 11lbs. will be bouncy, but I don't think its enough pressure to be dangerous though. You might want to even them out more, because you could end up having the rears being taller and mess up the ratio front to rear. While in 4wd, you need to keep that ratio close.

 

Andy's right about keeping the ratio fairly close-as far as tire heigths go. Running a higher pressure tire isn't necessarily bad, like he said, it will be more bouncy though. The other thing is, it will be more prone to puncture at higher pressures, as it can't "flex" as much, if you will. Run some slime, or Cabela's Tire X-tend, that will cure that problem!

Best of luck with the new Griz!

It will be fine but with the more air pressure it will have a better chance of getting a flat from a Rock or a Stick but it would be fine other wise and if you ride in mud it will be a little bit of an improvement!!!
P.S. watch out for sharp things!!!!!!!!!

 

If you run the higher pressures, you might want to run them back down for the soft stuff. If you run mud, sand or snow you will get more traction and flotation from the bigger "footprint" you get from a softer tire. In the soft stuff you dont have to worry much about cutting a sidewall or denting a rim. Just remember to air back up later.
