I blew a tire last summer running 75 and by the time I got it stopped the wheel was slightly bent. Single axle trailer, 15 inch tires, GALVANIZED wheels. Can anyone recommend whose wheels they would use with this combination. I have two different spares for it, both different wheels as I bought the spare wheel/tire combos at different times. Those spare wheels are MUCH lighter and less brawny than the one that I bent. As there are only two wheels and tires under my baby I want to be sure I get well-built, well -designed wheels to replace both. Thanks!
