I put on run-flat tires

They're working fine. They're a bit noisier and harsher riding, but we're willing to make that trade. The battery travel distance is so close to original that I haven't bother to make a close check. Yes, they can be repaired if they're in good condition after running without air. Bridgestone says that they're good for 50 miles at 50 mph, but then they're junk.

Because the tire won't flatten if it loses air, and I wouldn't know if it lost inflation, it needs the air pressure sensors. I have one (or more) bad sensors that I need to get fixed this week.

 

The car has been equally stable with both the original Toyo tires and these Bridgestone DriveGuards. Both felt fine. As noted in a different thread, check the inflation pressure. If that is what the placard on the driver's door jam calls for, then the problem might be intrinsic in the tire model which follows rain grooves in the pavement. Any chance you have the back end loaded heavy?

We aren't high mileage drivers, and we run snow tires in the winter. I haven't been tracking the tread wear, but it seems like the wear is very little.
