Michelin’s 80,000-Mile Defender Warranty Explained: What’s Covered (And What Isn’t)

Michelin offers an 80,000-mile treadwear warranty on two of its Defender tires, the Defender2 and the Defender T&H MTP. Only applies to replacement tires though, not the ones that came on the car from the factory.

Michelin calls it the Promise Plan. Three parts to it. First is a 60-day satisfaction guarantee where buyers can return their Michelins and swap them for a different new set priced the same or less. Second is roadside assistance for three years from purchase. Covers flat tire changes, tows up to 150 miles to the nearest Michelin dealer if there's no spare, battery jumps, lockout service, and delivery of fluids. Third is the manufacturer's warranty plus the 80,000-mile treadwear guarantee.

The warranty covers defects in materials and workmanship along with that 80,000-mile treadwear promise. Catch is Michelin also puts a six-year time limit on it from the date of purchase. So unless you drive at least 13,333 miles a year, you might not hit 80,000 miles before the warranty expires. Unless the tires wear out early.

What's Not Covered

Some big exclusions here. If the car needs different size tires front and rear, they can't be rotated. That cuts the warranty in half to 40,000 miles. Go with the run-flat version, called Zero Pressure or ZP, and it drops further to 30,000 miles.

Other stuff not covered: damage from racing, damage caused by mechanical problems with the car, road hazard damage, and damage to tires removed from the car they were originally mounted on. If you're not the original owner and bought the car used with these tires already on it, warranty doesn't apply.

More reasons for denied coverage: improper maintenance, underinflation, overinflation, bad wheel alignment, flat spotting from locking up the brakes or letting the car sit too long, and not rotating tires every 6,000 to 8,000 miles. Commercial use like ride-sharing isn't covered. Cosmetic cracking from weather or ozone exposure doesn't count. And using anything other than air, carbon dioxide, or nitrogen inside the tire voids it.

What Happens If They Wear Out Early

If the tires don't make it to 80,000 miles within six years, two scenarios can happen.

If the tires are less than a year old with less than 2/32" or 25% of tread depth worn away, Michelin replaces them free including mounting and balancing. Taxes and other fees are on you though.

Past that point or past one year from purchase, replacements happen on a pro rata basis. You pay a portion of the new tire cost based on the percentage of warranty miles you got and the current retail price. So if the tires wear down to the wear bars at 40,000 miles, you'd get a replacement for roughly half the current price. Mounting, balancing, and taxes still your problem.

Michelin ranks as the best major tire brand for customer satisfaction. Between the mileage warranty, 60-day return option, and roadside assistance, they're clearly trying to keep customers happy long-term.
