Front tire replacement
My 2007 Meridian 36G came with the Michelin XRV 255/80 R22.5 tires. After 5 years and 42,000 miles I am replacing ONE tire (Right front). A few years ago this tire started exhibiting signs of what is called "Shoulder Step Chamfer Wear". (I posted on this board about this wear previously). But just recently, while checking my tires, not only have the flat spots of this wear gradually got wider and longer, but there were also two distinct indentations visible across the whole width of the tread. These indentations are about 2 1/2" wide, and run diagonally across the face of the tread. The strange thing is that, looking at the tread face on, one "groove" runs SW to NE, but the other runs NW to SE, if you get my meaning, almost forming a "V" shape, looking side on at the tread, but each leg separated by about 3" at the base of the "\ /". And there are only two of these grooves, in just the one section of the tread, covering about 18" of the total circumference.
I took it to a local wheel alignment and brake place. They work on trucks, RVs and other big vehicles all the time, and they seem to know their stuff. We took the tire off, and the guy there said that that tire was defective, and I agree with him. The tread depth is good all around the tire, at about 13/32", except for the flat stepped wear on the outer few inches of the tread. I have bought a new tire, and they are fitting it this afternoon. I had them check all the alignment parameters (Toe in, camber, castor, etc) and everything is in spec. Also checked the steering links, ball joints etc. and everything is fine.So, my questions are :
- Has anyone seen this type of (potential) failure of an XRV tire with this kind of mileage ?
- Is there any point in going to Michelin with a complaint, after 5 years of use, and 42,000 miles ?
Any knowledgeable comments welcome
