Q: What does the lifetime warranty on the UP.FIT PD wheels cover?

It covers structural damage or defects for the original purchaser, non-transferable. If a PD wheel bends or cracks under normal use, Unplugged Performance replaces it. Because the forged monoblock is so hard to damage, that promise costs the company little and saves you the repeat expense of replacing cracked cast wheels. Normal wear and cosmetic curb scuffs are a different matter, but the core structure is backed for as long as you own them.
