Yesterday, I was driving on I-80 in PA when I got a low tire pressure warning on left front tire, but fortunately I was able to slow down and get off I-80 at Rte. 115 Exit (Blakeslee) and into parking at a Sunoco station before the left front tire pressure got below 25 psi. Had hex head screw in tire tread. Tesla was good about staying in touch with me via text messages and could have sent a flatbed to take me wherever I wanted to go up to 50 miles, but fortunately I did not need them to do this. They said that because I was 80 miles from the Service Center, a loaner wheel would not be an option. The people at Sunoco said Jimmy's Auto Service was nearby, on the south side of the interchange and I used my 12-volt air compressor (have one in each car) to pump up the tire to about 32 psi to drive about 3/8 mile to Jimmy's where they plugged the tire for me for $10.00 and I was able to make it home to Cleveland, Ohio without further inconvenience. Jimmy's was very good to me and I left them a $10.00 tip for each employee on site. I dodged a bullet . . . could have been a mess if I'd had to have the car flat bedded . . . although Jimmy's does have a flat bed as well. Needless to say, in addition to the compressor I always carry, I will be going to auto parts store today to get three tire plug kits for the cars, just in case and also adding a couple more tools for screw/nail removal . . . hope I never need them.
