Tires installed by Lexus on Sept 27, 2022 are shredding and coming apart in chunks at 37,000 miles; tire is rated 60,000 miles. This is 56% of the projected life of the tire. Previous tires, same brand and size, only lasted 29,000 miles; 1/2 of the life of the tire. Current tires have good tread depth and life left if the chunks were not uniformly coming off of all tires. This condition leaves the tire vulnerable to road hazards and moderately sharp objects. Failure is clearly imminent. Dealer, upon inspection July 1, 2025, did suggest immediate replacement of the tires at normal retail prices. No warnings or alerts or other symptoms are present. There has been a slight loss of air pressure.

235/55R20 102V Michelin Premier LTX, premature wear, tires falling apart in layers & chunks, caused premature failure of front left strut on Lexus RX350. Started at 24,000 miles. Tires create an oscillation, causing you to think a tire balance issue, no alignment issue in the onset of problem. Tire tread not wearing but appears to be melting and becoming brittle. Road weight balanced and numbers varied per location of tire original tire driver front read 14-15 pushing to close to the 20 number and giving perspective of internal or manufacturer defects or construction issue. My vehicle has been back to the Lexus maintenance shop for tire balance check, test drives, discovered left front strut was failing & replaced, alignment checked, tires checked again, then again at the shop days apart due to oscillation feeling continuing, tires road force balanced, test drive & again taken back with information of GMC bulletin for tire premature wear with an NHTSA. I’ve tracked complaints of premature wear/material failure issues from videos/reports online as well. This is a 60,000 mile tire/warranty failing at 20-25,000 miles. The tire problems only lead me to believe this could be another Firestone situation if left unchecked. It’ll impact vehicle owners & dealerships: repair & research time, money, premature vehicle component wear & repairs for allowing defective products to be allowed on US roads. Definitely not needed at this time of inflation & limited supply of replacement parts & tire products. I did contact Michelin customer service to file complaint/claim (#02983306) and informed the representative that this had been an issue for the month of June & didn’t feel it safe to have these tires on the road and also don’t want any further premature wear/failure of components to my vehicle or endanger myself or loved ones.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Lexus Rx450h verdict →
