Michelin PSII run flat tires plugged ?

[Peter M.]

Can the Michelin PSII run-flat tires that come on the 427's, Z06 and ZR1 Corvettes be patched or plugged? If so, can they be repaired more than once? Will such a repair void the manufacturer's warrantee on these performance tires?

Any insight here will be much appreciated.

Thanks,

P.

I got a nail near the center of my right rear Pilot Sport on my 2012 ZR1. The dealer refused to fix it, said a Z rated or better tire cannot be plugged or fixed. So I had to get a new set.

With a nail in the center of the tire and dealer refusal to do a inside patch, would a plug installed by owner keep air in a run flat?

Not a run-flat tire but just a Goodyear radial, the local Goodyear company owned store would not remove a screw near the edge of the tire and put a patch on the inside. Only choice was to replace. Drove down the street to another tire establishment and they removed the screw and put a patch installed on the inside. Thousands of miles on the repaired/patched tire now.

Because we are such a litigious society tire repair shops / manufacturers will NOT repair Z-rated tires.

I had a Goodyear GS-C run-flat patched hundreds of miles ago with no problems.

From the 2015 Corvette service manual. Did not see anything saying no repairs..

Run-Flat Tires
This vehicle, when new, had run-flat tires. There is no spare tire, no tire changing equipment, and no place to store a tire in the vehicle.
The vehicle also has a Tire Pressure Monitor System (TPMS) that indicates a loss of tire pressure in any of the tires.
Warning: If the low tire warning light displays on the instrument cluster, the handling capabilities will be reduced during severe maneuvers. Driving too fast could cause loss of control and you or others could be injured. Do not drive over 80 km/h (50 mph) when the low tire warning light is displayed. Drive cautiously and check the tire pressures as soon as possible.

Run-flat tires can be driven on with no air pressure. There is no need to stop on the side of the road to change the tire. Continue driving; however, do not drive too far or too fast. Driving on the tire may not be possible if there is permanent damage. To prevent permanent damage, the tire can be driven with no air pressure for up to 80 km (50 mi) at speeds slower than 80 km/h (50 mph). As soon as possible, contact the nearest authorized GM or run-flat servicing facility for inspection and repair or replacement.
When driving on a deflated run-flat tire, avoid potholes and other road hazards that could damage the tire and/or wheel beyond repair. When a tire has been damaged, or if driven any distance while deflated, check with an authorized run-flat tire service center to determine whether the tire can be repaired or should be replaced. To maintain the run-flat feature, all replacement tires must be run-flat tires.
To locate the nearest GM or run-flat servicing facility, call Customer Assistance.
The valve stems on run-flat tires have sensors that are part of the TPMS. See Tire Pressure Monitor System. These sensors contain batteries that are designed to last for 10 years under normal driving conditions. See your dealer for wheel or sensor replacement.
Caution: Using liquid sealants can damage the tire valves and tire pressure monitor sensors in the run-flat tires. This damage is not covered by the vehicle warranty. Do not use liquid sealants in run-flat tires.

Not all run-flat tires are high speed rated tires. Some run-flats are H speed rated or lower. Those have less chance of problems than a W, Y or Z rated tire if repaired.

Mucho information here:

Someplace I recall reading that if a run-flat speed rated tire is patched the speed rating no longer applies. I am unable to find that citation at the moment, however.

Re: Michelin PSII run flat tires plugged ?

The speed rating of the tire has to do with the carcass and belt construction. A plug in the center of the tread does not affect the carcass properties. The more important concern is whether the carcass was damaged by running under inflated after the pressure loss occured. Corporate a*s covering is the other consideration.

Re: Michelin PSII run flat tires plugged ?

I had a PS2 plugged on my 2002 Z06 to remove a large screw. This was 3 or 4 years ago. I don't drive the car hard, but I do put a lot of miles on the car. So far so good.

Re: Michelin PSII run flat tires plugged ?

2005 Corvette. Pawley's Island S.C. Driving down the night of vacation hit a 6 inch long 1/4" allen wrench with the right rear tire. Dead flat the next morning. Hit the station across the road, got air, headed straight down the road to Coastal Chevrolet to see if they could repair it. Thought it was one of those interchangeable screwdriver bit tips at first by the look of it. The took the tire off, patched it and I drove it till they had to be replaced. The long end of the wrench went into the tire first.
