Coming back from a camping trip, I got an alert from the TPMS saying that my right rear was at 26 PSI. Rutroh.
Turns out I got a piece of metal stuck in the RR. This morning, the tire was completely flat....well, as flat as the RFT Driveguards get. Drove over to the local Costco to get it checked out (hopefully the repair/replacement is covered under their road hazard warranty).
On the drive, I could barely tell the RR was even flat, aside from a slight flapping sound coming from it.

Verdict: razor blade in the RR (what the). Due to the way it was cut, Costco guys said it could not be patched and a new tire would have to be ordered. They measured that 25% of the tread was used, so I had to pay 25% ($45) of the cost of a new tire, which should come in either later today or tomorrow. So till perhaps tomorrow, I'm rolling around on a "flat" tire. The Costco guys did at least air it up, but it'll probably be flat again by the end of my work shift.

If I had the OEM Goodyears, I'd be SOL for sure.

The right rear of the gen 1 Volt seems to pick up the debris for me. But it never caused anything but a slow leak on the goodyear tires.

I thought Drive guard tires could not be repaired and put back into service anyway, once they have been driven on without pressure. The sidewalls get sacrificed when driven like that. Good thing you got the road hazard warranty. Also be careful about your total mileage while waiting for the replacement. I think they are limited to 50 miles when flat.

I had one of my Driveguards patched because I got a nail in one literally a month after I bought them. Now that I think about it, I think it was the RR too! And before I got the Driveguards, I had one of the OEM Goodyears patched as well (also RR!). Man, wtf is up with RR's and punctures.

...Man, wtf is up with RR's and punctures.

Maybe it is because the RR is the tire that gets closest to the edge of the road when turning. The rear tires track inside of the front tires when turning, and right turns (in most of the world) are normally done by the edge of the roadway (rightmost lane). Maybe the small debris that causes punctures tends to accumulate by the edge of the road.

I recently (about a month ago) had DriveGuard tires installed. I have noticed that the battery charge level has gone down about 3 or four miles. Anyone else with DriveGuards noticed this?? No big deal for me, just wondering.

Yeah, you're gonna take a range hit. The Driveguards are heavier (those tank sidewalls!) and have higher rolling resistance than the OEMs. But at least you'll never have to worry about being stranded on the side of the road with a blow out!

Yup -- I've had mine for almost a year. I *think* overinflating to 44 has helped a little bit, but overall it's been a 10% penalty that hasn't gotten better. I used to regularly get 48 EV miles in moderate temps, but have only seen that once. Oh well, still getting 100 mpg lifetime so I'm happy.

Other than the noted loss in efficiency, how are the driveguards for driving. I'm looking at road noise, handling (wet and dry), etc. I'm debating these vs. the Turanzas when my OEM Michelins wear out.
