What does having a spare tire mean?
Also, what does it mean to have a spare tire?
A spare tire (or stepney) is an additional tire (or tyre - see spelling differences) carried in a motor vehicle as a replacement for one that goes flat, has a blowout, or has another emergency.
One may also ask, what does a spare tire look like? Spare tires are full-size tires that are the same size as your existing tires. They are much smaller than your regular tires and are only meant for short distances until you can get a new full-sized tire. You should not drive at high speeds on the donut or drive on it for an extended period of time.
Moreover, do you have to replace a spare tire after using it?
Rather than going flat or blowing out (as traditional tires do), a run-flat tire can continue to drive after a puncture for about 50 miles before needing to be replaced.
What happens if you drive too fast on a spare tire?
It should say right on the side of the spare tire, or on the wheel itself on a large, prominent sticker. If that's missing or illegible, the rule of thumb is to not exceed 50 miles per hour. Going faster could cause tire failure, differential damage, or both.
