215/65r-16 michelin defender sl; less 15k miles driven a cut through outer layers of sidewall and windings visible. Thought it was likely some unnoticed road hazard until happened to second tire: again, do not recall any incident likely to have cut the tire. In 40+ years of driving, only these two sidewall cuts, on same make of tire, make me wonder if the compound is inherently weak. Photo available of second cut.
2005 Toyota Sienna le ims rampvan I replaced all 4 tires w / pirelli 215 / 65r / 16 centurato p5s in may 2009 at approx 16500 miles, oem dunlops were unsafe according to a google search, I went to americas, they said the pirelli is the best, im a quadriplegic & I need a reliable vehicle we as we all do. . . . I had a flat tire, aaa changed it they said it had cracked sidewalls & cord was showing between the tire tread & the sidewall as if had been on a lathe, we took pics of the worst tire & we have 2 more of this brand on the front axle w / a similar wear patterns. . . Im a disabled certified mechanic & I have done 100s of alignments & I have never seen a wear pattern like this, we took it back to where we bought them to have it checked out, we did & they said the tire had an unusual wear on 1 side of the tread / sidewall & they needed to replace all 4 & the warranty did not cover it, so we had to buy 2 for the rear axle as that's all I can afford at this time. . . . . They told me it needed a 4 wheel alignment & all 4 shock absorbers replaced too. . . . My crookdar went off & I play dumb to see what they say & I start documenting everything. . . I have it checked out at the dealership. . . Took my Sienna into the Toyota dealership for its 40k service & told them what America tire told me, the dealer checked it out & said it didn't need an alignment & the shocks seem fine to them but might need replacing only because my vans 9 yrs old & that the 2 front tires are weather checked & are dangerous. . . . . . . So I google pirelli tire complaints & bam, theirs 1000s of people w / the same problems as myself. . . . . . So now I go to war w / americas tire & pirelli.
