Default Rears at 60%. Replace both?

So it seems I have a picked up a nail right smack dab in the middle of one of my rear tires. They are at 60%. Is one new, and one at 60% a problem? Would you pick up a second? The first will be covered by my tire and wheel insurance.



Nail in my rear P-Zero.

Was really hoping my next set would be Michelin PS4S’s, so I’m half tempted to try and track down a set of those

, but the cost of eating one tire, doesn’t sit well.

If you are not tracking your car, I'd plug the tire and call it a day. No problem.

If you are not tracking your car, why not repair it?? I had the same thing happen. Dismount the tire and inspect the puncture area for any unusual damage and then do an internal repair. Just don't use an external plug and hope for a permanent fix.

Is it even leaking air? May be superficial.

Right rear? It's always the right side.

When you say 60%, I’m assuming that is based on tread depth. How old are the tires? If 5 years or more, replace all of them. Otherwise, the damage appears to be in a fixable part if the tire, (barring track usage), and a plug repair should be fine.

Had almost the same happen to me on December. Big bolt on the right rear tire. I did repair the tire on the inside and no problem.

When I took the car to repair the tire, it was the day after a track day and tires were looking tired...... The guys told me that they could repair the tire but that in no way it was going to be able to be balanced because of the wear. I insisted on the repair and all four tires balanced perfectly. The guys were obviously trying to sell me a new set of tires.

Don't know if I would mixed a new with a used tire in the rear......

You can mix new and used tire if the old tires are 30% wear or less, I think.

I would put a string plug or have a tire shop put an inner plug on that and keep driving

He's got wheel and tire insurance. Doesn't make sense to plug. I'd spring for 1 new rear and get the shop to credit you what they can for a 60% remaining rear.

I'd get the tire patched professionally. Did that once already and has been fine. Maybe not if I tracked the car vigorously on a regular basis, though. But a lot cheaper than replacing.

You need to either replace both or just fix it. If you fix it, it would cost you 25-40. If you replace both, probly 350-400 for one side. If the fronts are worn, spring for a white set of 4s Michelin’s.

Would your insurance cover a new tire or do they prorate it? If they cover the whole tire, just get two new rears unless your fronts are worn too.

I have simple approach to this type of issues.
If fixable, fix it.
If not, replace both.

The steel belts may have protected the tire and just folded the pointed end of the nail over without puncturing the tire.
The rear tires usually wear out twice as fast as the front tires. If you replace both rear tires (one with insurance/one on your own), all four will probably wear out about the same time.
I replaced my worn out rear tires with Pirelli tires to match the 40% worn factory front tires. When all four wear out about the same time . . . I plant to get the smoother & quieter Michelins.

I repair most tires but in the 911 I typically just don't take the risk and replace it. I know, I know, it is probably going to be just fine, but with a $100K car on top of that plug, my risk aversion goes into hyper-mode.

Repair it and keep the good one as a spare for the next time you get a puncture, and hopefully it will be at the right wear level.
