Those are identical to my 06' Lexus GX-470's, Michelin LTX M/S2 tires. Changed in 2013 with 40k miles and both tread and sidewall's are dry rotted. This is my first set of Michelin's that have done this. I'll be replacing them next month.
I actually have MXV4 on another car and now worried to see this happen to those too.
There was a recall on LTX M/S2, but only specific sizes.
Michelin is voluntarily recalling certain sizes of its MICHELIN® LTX® M/S 2, MICHELIN® X® Radial LT2 and MICHELIN® LatitudeTM Tour tires. These tires are typically found on light trucks and SUVs.
The tires were produced between September 2012 and early June 2013.
Sizes are as follows:
MICHELIN® LTXTM M/S 2: P275/55R20 111T RBL, P265/65R18 112T and P265/60R18 109T ORWL
MICHELIN® XTM Radial LT2: P265/65R18 112T and P275/55R20 111T
MICHELIN® LatitudeTM Tour: P255/60R19 108S and P255/70R18 112T
Michelin is recalling approximately 100,000 tires in order to retrieve an estimated 2,500 tires (about 2.5% of the recalled population).
Affected tires could have partial or full sidewall perforations that could cause them to experience loss of air pressure.
