Do You Really Need a Spare Tyre?

Many of today’s cars and trucks now come from the factory equipped with inflator kits and tyres that promise to eliminate the need for a spare tyre. Most of us take our tyres for granted until there’s a problem, and it’s good to have a spare because you never know when an accident will happen. A spare tyre and wheel offer a seamless, direct replacement that puts you back on the road again. Check out Purnell Tyres and be prepared for your next adventure.

Small Spares: Useful in a Pinch

Of the modern vehicles that do come with spare tyres, most have small spares. These units are made smaller to increase fuel economy and cargo space while decreasing weight and expense, and it’s best not to drive on them for extended periods. Don’t wait until you’ve been left stranded to purchase a spare tyre. If your car or truck does not have a spare, consider making the investment.

Full-Size Spares

A full-size spare tyre is the same size as a vehicle’s other tyres. The biggest benefit of having a full-size spare to go along with your KMC wheels is that it provides a long-lasting fix. It’s important to have your tyres rotated regularly, including the spare, so they wear evenly. While a full-size spare wheel and tyre offer a direct replacement, they do take up more space inside your vehicle.

Temporary Full-Size Spares

A full-size temp spare is of the same dimensions as your vehicle’s other tyres, but it differs in terms of weight and tread depth. Temporary full-size spares are lighter, so they’re easier to install.

Compact Spare Tyres

Sometimes referred to as “donuts”, compact temporary spare car tyres are meant to provide a short-term fix until you can make it to a tyre repair shop. These tyres are narrow and small, so they take up less cargo area. However, their shallow tread depth makes them risky to use for long periods.

Folding Temporary Spares

These collapsible, foldable tyres require inflation beforehand. They’re meant to provide an emergency solution that will last long enough to get you to a tyre installer.


These days, many automakers are including run-flat tyres in place of spares. These tyres are designed to withstand road perils such as punctures and can be driven for about 65 kilometers before needing replacement.


Flat tyres are a random occurrence that can’t be controlled, so it’s best to be prepared by keeping a spare tyre in your vehicle. No matter which type of tyres your vehicle has, it’s important to keep your spare in good condition. Driving long distances on a spare, especially a donut, can cause damage to your vehicle and its components such as EGR flares. Inspect the spare when you’re checking your tyre pressure each month, and when the tyres are replaced.
