Screwed Again!

Well, actually it was a piece of metal that pierced my right rear tire.

Metal debris puncture

Walked into the garage this morning to see my three week old new Michelin tire flat as a pancake.  ARRGGGHHHH!  My initial thoughts were that the tire had been installed improperly by the dealer.  A quick peak around the tire and I spotted what looked like a nail stuck squarely into the tire in the center of the tread.  Crap.  If you follow this blog you may recall I got screwed in December 2016, almost exactly a year ago.

I followed my own blog posts for Single Point Jacking and Removing a Road Wheel and bummed a ride from my neighbor Rob with my flat down to my local Les Schwab Tire Center (thanks Rob!).  I dropped it off for a patch, and in two hours it was ready for pickup.  The fee – FREE.  I’ve mentioned this before, the guys at Les Schwab do a great job looking after their customers.  Thanks Chris and the boys!

I followed my own blog posts for Torqueing the Wheel Nuts (I can’t remember the two torque settings) and double checked the tire pressures on all four corners (36psi up front, 38psi in the back, cold).   Back on the road again!

There was a great comment left by John Armitage asking about if the puncture destroys the ‘Speed Rating’ of the tire (DB9 tires are ‘Y’ speed rated).   I wanted to find out so I started to Google it.   TireRack.com has this article specifically about it (click here to read it).

Patch/Plug repair in place

In it, they list that some manufacturers will maintain the Speed Rating as long as the tire is properly repaired using a combination plug/patch after being dismounted and inspected by a qualified technician.   My tires are Michelin’s, and are listed as ‘Maintained’ so the answer would be a ‘yes’ I guess.  I have reached out to Michelin directly for a reference (and will update the article when I learn more).  In the list you will see that many other manufacturers (including the OEM tires by Bridgestone) Void the speed rating as they have no control over the inspection or repair and opt to drop the rating.   What does this all mean?  If I was going to drive for hours at 185 mph I think I would just replace the tire.  Since I top out about 130 mph for a few seconds at a time once per year at an AMOC Track Day, I think I am just fine with it since Michelin is.

What a Patch/Plug looks like

Michelin has confirmed this, here is a the email thread:

Hello Steven,

Regarding your email stating:

————————————————————————–
I have new Y speed rated Michelin Pilot Sport tires. I got a
nail in the center of the tread. I have had it repaired with a patch/plug  at a Les Schwab tire center. My question is is the Y speed rating  maintained?

Please let me know, and if possible provide a link to this info
online (I searched your website and could not find an answer to this).
Thanks! Steve

The patch plug is the correct repair and yes it does maintain the Y speed rating.

  1. Steve My question is : if one has a puncture on the road does one use the AM inflating kit with the “goop” inside or not. If so can the “goop” be removed and the tire salvaged. I carry a portable air compressor in the vantage at all times so if the leak is slow enough i could perhaps get to a tire shop

    Ah the joys of motoring. I’ve had the same experience right after buying new tires. I know, sucks to treat your baby to a brand new set of tires only to get a puncture. I’ve had a tire shop tell me they wouldn’t fix a puncture if it is on the outer edges of the tread. Good at least yours was mid tire so you didn’t have to replace it. Removal, then patch and plug , remount and rebalance is the best way to go.
    Glad to hear you’re back on the road, nice response from Michelin. Good to hear they hold their speed rating when others don’t. Sounds like you made the right choice of tire. How do the Michelin’s feel compared to the Bridgestones.

    John has a good point. I wonder what your tire shops reaction would be to having a tire and wheel full of goop Steve. I would think the stuff would be cleanable but at what extra cost.?
