Still not sold on the run flats without a spare. On vacation from Edmonton made it to Banff, with plans to head on to Panorama the next day, and I got a flat tire indicator ( 7pm). I refilled the tire let it sit over night and the next morning it was down 5lbs. So back to Calgary I go, not in the best mood when I got there. Don did a great job of getting me back on the road quickly even though we had to wait on receiving a tire from a local shop. Thanks again, on to the rest of my vacation.
