Those front tyres look like they are scolloping by shadows that are cast on the tread edges, due to under inflation, also causing heat buildup.

Went to discount tire this morning, when tec took a look the tires, he called them as "tread chunking tires", since it all over the tire surface on both tires, it's definitely manufactory defect, this is quite common defect and could happen to all brand of tires.

He measured the tire tread at 5/32 and recorded some numbers from the tires and told me he was going to call Michelin to get those two tires replaced.

But after 3 minutes call from Michelin, I was offered to replace the full set of 4 tires by Michelin at 50% of cost. I took it immediately considering only 3/32 tread life left on those tires ;)

Here is the breakdown of cost, of course, I won't take the bite of $164 free replacement certificates. Tires will be ready in 3 business days, it's good timing to get new tires for winter.

Ha. So much for the scrubbing the tires by the wife theories:bustingup

I like the road hazard plans, especially if you'll get 40k out of the tires. BMW sells their plan for 1300-1800, here you are getting it for much less. All you need is ONE 'non-repairable' flat on any of the 4 tires over the next n years and you are ahead....

Really, I don't realize those tire plan could be that expensive, I bet BMW plan probably covers the rims too, otherwise it's really ripoff.

I just read the terms, the certificate covers original tread down to 3/32 or 3 yrs from the purchase. Based on our experience on those tires, the tires probably can last up to 30k or 1.5 yrs for us.

I didn't get a single flat in the past 10 yrs, that's why I thought to skip it in the first place. I may reconsider that since these tires are RFT and non-repairable.

RFT are not non-repairable. An individual puncture may be non-repairable, based on the location of the hole (how close it is to the sidewall) and how long it was driven on underinflated (due to heat damage).

I see, I will get more details about how warranty terms play on RFT.

Haha. Ok. I stand corrected. At least according to this tire guy. No way to be sure what started the chunking though :stickpoke

OP, Glad you got it sorted.

Damn good deal for 4 new skins, miamipanther...
Glad you got it covered.
GL, mD

It's the same as if you were to get two fronts free and buy your own rears. I would have told them to give me two fronts free because they're defective and perhaps give a discount on the two new rears, otherwise I'd be going elsewhere for my RFTs.

Then again, that's me.

That's how tire warranty works.

The tire manufacturer warranty prorates the cost of the new tire based on the percentage of remaining tread on the old tire and the price of the replacement tire.

So for 5/32 tread life of the tire(10/32 new, 2/32 bold), 50% of cost is quite decent for me, especially it not only applied to defected tires.

Here is the info regarding Michelin warranty:

Workmanship/Materials

If a tire is covered, and 2/32nds of an inch (1.6mm) or less of the original
tread is worn (or 25% or less, whichever is more beneficial to you), and it is
within 12 months of the date of purchase, we will, free of charge, replace
your tire with a comparable new MICHELIN

basis. This means that you will be responsible for paying a portion of the
cost. The Michelin tire retailer will determine the portion that you will be
responsible for by multiplying the percentage of the original usable tread
worn, by the current selling price at the adjustment location or the price
in the current Michelin Base Price List, whichever is lower. You also will be
responsible for paying in-full the cost of mounting and balancing the tire,
and the cost of any other service charges and applicable taxes, including

PAX Gel/Gel 3 packs.
