Not true, get a spare tire, wheel optional, if you travel on weekends, holidays, nights etch, and you have a flat you will be really happy you had it. Having had 3 flats in my rving life I speak from some experience, had a flat on I 95 in Florida on mothers day, called road service, first question. Do you have a spare? When service guy showed up I asked him if I didn't have a spare what were my consequences. He said it has been a busy weekend and they were sold out of tires in my size. Should get some in by Tuesday or Wednesday. Then I questioned prices, 25% more than I paid for the spare I was carrying.
