It covers 100% of the cost of the new rim but does not cover shipping or labour charges. Our crash replacement  policy covers damage that is caused by casing jumps, hitting square edges at speed, backing over your wheel with your Tacoma, and of course a gnarly crash. The crash replacement cost is 50% of MSRP
