Nail in Tyre

SteveC · 04-19-2015, 03:55 AM

Set off early this morning and the tyre pressure warning went off after 100m. Back home the tyre in question was at 2.00 Bar, the other 3 at 2.41 where I'd set them a week before.

Rolled the car down the driveway and sure enough there was a large flat headed nail right in the very middle of the tread.

The tyres (non run-flat Michelin PSS) have done 3000 miles and have slightly over 6mm of tread depth remaining.

Given that the puncture is right in the centre of the tread and the tyre has not been run below 2 bar and then only for 200m, what would you do if it was your car.....
a. have the tyre repaired and forget about it?
b. replace the punctured tyre, leaving a new and used tyre on the same axle?
c. Replace both tyres, thereby ensuring no accelerated wear on the diff?

Personally id go with b.
Having a repaired tyre on such a high performance car always makes me worry about internal tyre damage.

If you do repair, make sure its the correct type of repair.

I've patched tires before and it's fine if you get it done properly (tire off rim, patched from inside and plugged).

Most recent was tires from my gtr at 5k miles. Put another 12k on them and a few track days and they were fine.

I had a slight "crack" on the front right tire and replaced both. Threw away the bad and the one used one in the garage. For $700 U.S., just the peace of mind.

Get the tire plugged with a gator, it should be 100%

Sorry that sucks, I know the feeling all too well.
I run Michelin PS2's and always get them repaired. I put my trust in advice from the chap who supplies/repairs my tyres - but thinking about it now, I should have come here for advice.
Thanks for that video E90fleet, I will pay more attention to the process if I get a repair done again. It's definitely made me think twice. In future I think I'd go for a repair if the tyre has 5mm+ and damage appears to be minimal.

Repair and move on.

M6-Coupe · 04-19-2015, 05:37 PM

Have them repaired. It's safe and reliable (as the video says) if a good shop gets it done...

Thanks for the feedback....most appreciated.

Well in the end the choice was made for me.

When we took off the wheel it looked like there were 2 injuries to the tyres....a screw and an odd shaped nail, so I decided to get 2 new tyres.

But when it came to ordering them, we found out that they are not in stock in the UK and that delivery is 2 weeks from Michelin

. My tyre (tire) shop offered to remove the tyre to take a closer look at the damage. What they found was that only one nail had penetrated the carcass at 90 degrees. The other was just a small stone embedded in the tread which had not penetrated the carcass and could be easily removed.

In the end they did the repair, following exactly the procedure on the video (they had a large wall poster showing how its done.) Having seen the materials, the preparation and the workmanship, I'm pretty confident that the repair will indeed last the lifetime of the tyre.

Ex_Stig · 04-21-2015, 10:42 AM

I wasn't as lucky. Just discovered this yesterday. Looks too close to the inner sidewall to repair.

SteveC · 04-21-2015, 11:59 AM

That's a bummer. Just looking at the photo is kinda depressing. Feel for you buddy.

Somehow its not the price of the tyre....its the hassle and more than that, the waste of tossing an otherwise perfectly good tyre

IshR · 04-21-2015, 12:21 PM

I've always wondered how and why ppl get so many punctures. Why are there so many nails/screws on the road and how do they go from lying horizontal on the road to puncturing vertically into a tyre?
Does speed play a factor in dictating when this is most likely to happen?

Whenever we have a house being constructed within like a 20 mile radius, I somehow manage to find a nail.

Has for how it 'stands up' - I would imagine that as the head is pushed down, the tip flips up a bit and the rubber catches it.
