In over 40 years RVing, I've had only ONE flat, last year. Coach Net sent a guy out with a new Goodyear, date code 8/2014, changed it on the side of the road and I was back in business. Extended warranty paid for the service call AND the tire. Didn't cost me anything but an hour wait. Allowed me time to wax one side of the coach....do the math..it makes little sense to carry a 200# spare that I'm not going to change anyway. That's 200# of extra food, beer whatever that I can carry.....Dennis
