Is polyurethane tougher/better than rubber/plastic?
Polyurethane typically outperforms rubber in areas of abrasion and wear-resistance. Polyurethane is less susceptible to rotting and deterioration than rubber. However, in high-heat (200°F+) environments, rubber may be a preferred choice.
Can my existing cores be resurfaced/retreaded?
Yes. As long as the base core is undamaged, your wheel/roller cores can be recovered multiple times.
