the HF stuff wont last a week, those wheels you bought are also used on cheap racing kart stands and in no time the bushings are gone, they bend too easily, and can come apart.....
Those HF wheels are not designed to be put on a kart, they are for little wagons and such
How much is the safety of your children worth?
It has a max load limit of 300#, how much does the kart weigh with your kids in it? how many pounds of force will be applied while cornering?
Did you read the description or did you take the word of a non skilled phone person at HF that they would work?
"This pneumatic tire is the perfect replacement for wagons, hand trucks and yard trailers. "
And dont come at me with that engineer stuff, im a project manager for the 4th largest Commercial masonry company in the US, I deal with engineers on a daily basis, having that paper doesnt mean "smart".
