    I can hit about 35-36 psi max--but I guess you're probably talking tire pressure. [​IMG] I'd say probably max pressure for the tire (around 35 psi?). 15" wheels?

    I'd run 35psi if thats max... If you can go higher I'd run about 45-50. Remember, You'll need 10-15% tongue weight. roughly 500-700lbs. Be careful, thats a lot of weight on the tail end of a K5.

    When in doubt, slow down, esp with a trailer. I'd also make sure your trailer brakes are working.
