Hey all,

Just replaced the stock Dunlop Grand Trek 265/70R16 after 48.5 k miles with Bridgestone Dueler A/T Revos 265/75R16 D load...

These are GREAT tires -- question -- the tire guy ( did not seem to know what he was doing really) put about 32 psi in there...

I drove around a little bit and they seemed a little soft, so I put them up to 35 psi... they still may be a little soft ?

What are you guys inflating your Duelers (in this size) to for on-road / highway driving?

I fill the fronts to 30 and the rear 33. Its the best setting for my 4-Runner.

 

That is interesting. I usually run equal pressures on my front-engine cars or occasionally slightly higher PSI on the heavy end (front).

Mike,
I just replaced my TG-35s with 275/70/16 Revos and have them at 33 psi. They feel great, but I may notch them up to 34 psi cold.

As for different tires pressures front / rear on a 4WD, I've always heard this is not recommended as the drivetrain will bind since the tires will not be rotating at the exact same speed. Naturally the newer 4Runners with multi-mode 4WD will be unaffected, but its probably still a good idea to keep them all at the same psi.

The recommended pressure settings from the factory are like 29 front 32 rear, you get a basis point there. The next thing you do is follow wear patterns on the treads. To much wear in the center is overinflated, outer wear is underinflation. You need to balance all this with handling, comfort, etc..

 

Amkeer-- re: the 29 & 32 -- but that's for the factory size tires, no? 265/70R16 ?

The newer slightly larger tires just seemed real soft at 32...better at 35... wondering what other people run them at.. for highway/road driving..

 

I know that on my Syncro this is true but it's AWD and the VC notices the difference in rotation and tries to shift traction. Since our 4WD trucks are never in 4WD unless the surface is slippery, the slight difference in PSI should not really matter, IMHO. I would not run different size tires mind you but the changes that PSI make should not cause any trouble in a 4WD.
FWIW, my 4Runner runs equal pressure all the way around. The Mrs. Cherokee is, I think, running higher pressure in the front.

I run mine at 35 psi.

 

I have found that 35 psi works best on mine. The dealer had them at 38 when installed, but the front end felt a little 'squirmy', so I started dropping them one lb at at time till I got to 35, they seem to work best for my ride. But you can also check the Bridgestone site, they give pressure suggestions for the different types of tires they have. You will find almost as many different recomendations for tire pressure as you have replies. In general, I would go with what feels best for your ride, and observe tire wear patterns and adjust accordingly.
