    The tires on the Niagara are 205/75R14 50 PSI GY Marathon LRC(capacity 1760lb). I would like to replace them with the new GY Endurance tires. These are LRD(capacity 2040lb) tires with a speed rating of 87mph. They are however need 65PSI while the Marathons are 50PSI tires. I can't seem to find a max rating on the aluminum Niagara wheels. Googling seems to suggest there should a stamped rating inside a circle on the wheel, but I don't see anything like that. Another 15PSI doesn't seem like it should be a problem. Does anyone know anything about the Niagara wheels?

    Rims are usually stamped inside with the size, pressure rating etc..

    By inside I meen what is currently covered by rubber...

    Don't know about your wheels., but at 65 PSI I believe that you will need to replace the valves with a bolt in

    Well, that's useful, I won't know if I need new wheels until I get to the tire store and have the old tires removed. Guess I better figure to take off the wheels at home.

    Strangely enough, one wheel has a steel valve and the other a new rubber one. not sure how that happened.

    Both valve stems were probably steel vales to start with and someone damaged one by using an aluminum cap and replaced the metal stem with a rubber one..
