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.
Original equipment in Lexus Rx 350; michelin premier ltx 235/55/20 at less than 2 years and 14, 00 miles run advised by the manufacturer to replace for a new one because premature tire deterioration with risk of impending tire rupture. Advised that they have seen a situation is occurring in the same vehicle and these specific tires. Yet no recall and the replacement at the owner's expense. Same situation in the 4 tires. This is a safety issue that both te tire manufacturer and that car dealership are aware of.
