If they are, in fact, cheap HF wheels, it would be a shorter list to say what's good about them, which is nothing!
-The rims themselves are made of thin, soft steel
-The bearings will disintegrate in about 5 minutes at speeds above 10mph
-Ditto for the tyres
-The word precision doesn't exist anywhere in the production of those wheels
The $5 HF wheels are dolly wheels, not go kart wheels & are only meant to be used for light duty, low speed applications
I have a bunch of similar wheels, I use them on the front of my daughters go kart because it's only a low speed kart, & on my kart trolley but, even the pair on the front of my 5mph riding mower are starting to break after only about 5 hours work...
