    What psi fro 35\" BFG MTs on road?

    I have newly installed 35" BFG MTs on 15x10 wheels. What psi would you guys recommend running for in town driving?

    Well, i have the 35x12.50x16.5s, so will be a bit different cause of their higher weight rating...but I run them at 40 psi on the street, that way I get all I can out of the fuel mileage and they wear well...my buddy with an F250 runs his at 45, but 40 feels just right on mine.

    When I had the 15 inch wheels with 35s, I used to run about 30-35 and they felt fine on the street.
