I also have roadside assistance, which has an amazing towing range of 150 miles. But I simply refuse to be stranded by something as simple and common as a flat tire. I almost died once from a flat tire, and it was not because of a crash. My '76 CB750 had a flat on the rear tire about halfway between Yuma and Gila Bend on I-8. Though it had a centerstand, I did not have the tools to fix a flat. This was before the advent of cell phones, though there are still sections of that road where cell phones don't work. It was over a Fourth of July weekend, and about 120 degrees. Nobody stopped, including bikes. I was fading fast when a highway patrol cop stopped. He had water and A/C in the car. He called a tow truck out of Gila Bend, they hauled the bike back into Gila Bend, where I spent the night, and called relatives in Chandler to come and haul me and the bike back home.
I ride a dual sport bike all over the AZ desert, And have had to fix many flats out on the trail, where roadside assistance would be worthless. I have an aftermarket centerstand on the bike. And I am seriously considering getting one of those SPOT devices.
