I go through rear wheels pretty regular. They deform and get misshapen. I would go through a couple a month if I changed them when I should. This is what I think I need;
I need a rear wheel that is 150 on the hardness scale. I need it made out of some sort of strong plastic or even metal. I figure if I keep the 1st 3 wheels regular outside wheels I would not have to worry about grip.
Is there such a wheel?
