Most drivers never think about their spare tire until they need it — usually on the side of the road, in a hurry. Here’s what to know before that happens.
Full-Size vs. Compact (Donut) Spares
Many newer vehicles come with a compact spare, often called a donut. These are smaller and lighter, but only meant for temporary use — usually at reduced speed, for no more than about 100 km, just enough to get you to a shop.
Check It Before You Need It
Spare tires lose air pressure slowly over time, just like regular tires. It’s worth checking the pressure on your spare a couple of times a year, so it’s actually usable when you need it.
Spares Have an Expiry Date Too
Even if it’s never been used, rubber degrades over time. Check the manufacture date on the sidewall (a four-digit code, week and year). Most spares should be replaced after six to ten years, even with little to no use.
If You Don’t Have a Spare at All
Some newer vehicles skip the spare entirely and rely on run-flat tires or a tire inflator kit instead. If that’s your car, it’s worth knowing exactly what’s in your trunk before you’re stuck needing it.
