Tire max speed

    Hey guys,

    My Hijet easily runs 120kmh on the highway (which according to my GPS is really 65mph (105kmh)), but I'm a little unsure about the capabilities of my tires. They are winter mud/snow 145/80R12 tires 3 ply but I can't find an indicator on them about max speed rating. Their max inflation rating is 35psi and I keep them at 33psi (even then the front tires look pretty burdened even when unloaded).
    So I just don't want to be driving down the highway at 65mph if the max speed rating is 45mph, ya know?

    Here is the brand if that helps:
    4 Good Year LTR Snowmark Tires P145/80R12

    Thanks,
    ~Josh

    :) Ah, good to hear. So I suppose because they say DOT on them it means they are street approved.
    Thanks,
