This is what I posted in Suspension forum, but looks like it's turning out to be a tire problem rather than alignment issue.

I visted Lexus dealer and their tech told me this is common issue with Michelin Pilot Sport A/S Plus tires.

They simply go bad after 4+ years. I've seen many old tires with dried/cracked rubber.. but nothing close to this.


My tire is cracking, dried and it is basically falling apart.. (quickly too)

Quick google turned up few other ppl with similar issue.

Anyone else experienced same issue?

I just wanted to confirm that I'm not having some weird suspension issue..

 

I has those tires on my G35. Loved them. Never had any issues but depending on your climate they might be dried out and just plain old.

 

I've heard horror stories about those tires, never seen it in person before though. That's definitely not an alignment/suspension issue, you can see that the untouched rubber in between the tread blocks on the shoulder have already started to crack. Get yourself some new tires, and soon, that looks like a blowout waiting to happen.

 

Thats normal wear from that tire..i used to sell michelin tires and that is normal wear for these tires..nothing wrong with the tire its just the way its wears that gets people scared..im not saying its a good tire but nothing wrong with it either

New tires are on the way already.

I justed wanted to make sure I'm not dealing with any other suspension issue before I ruin new set of tires.

Thanks for your reply!

 

I'm sorry, that's far far from 'normal' wear.

 

I believe Michelin uses abnormally large proportions of natural rubber in their compounds on some of their tires (pilot sport a/s included). The natural rubber dries out faster which leads to chunking and high degradation after only a few years. OP- you need to increase your tire pressures as well!

 

My buddy has these same tires on his M5 and they are suffering from the exact issue in this picture. I personally would get rid of them and not buy any more.

 

Thanks for the reply.

New tires are on the way. Staying away from Pilot Sports...

 

I meant thats how the a/s plus tires will wear out. Its mormal for those tires to wear like that.Im glad u got different tires im not trying to make u keep those..i was implying that these tires specifically will always have a wear pattern like the picture u posted doesnt matter on the car they are mounted on. Good luck
