How to look after your motorhome’s spare wheel

When you’re preparing for your motorhome adventures, it’s easy to focus on the essentials - for example, checking the motorhome’s existing tyres, stocking up on supplies, and planning your route. However, one crucial element that’s often overlooked is also taking care of the spare wheel. Whether you’re heading off for a long journey or just a quick weekend away, ensuring that your spare wheel is in good condition can save you a lot of trouble on the road.

Here’s our comprehensive guide on how to care for your motorhome’s spare wheel, making sure it’s ready for action, if and when you need it.

Why having a spare wheel is important

A puncture or damaged tyre can happen at any time, and when you’re driving a large vehicle like a motorhome, it can be even more of a headache. Having a spare wheel available, and in a good condition, is essential for your peace of mind. You might think about just calling out your motorhome breakdown service, but if you’re in a remote area, you could end up waiting a long time for assistance - and there might be additional charges if you haven’t got a spare with you that can be used.

Your spare wheel is your lifeline in these situations, allowing you to get back on the road quickly. But like any other tyre on a vehicle, it needs proper care and attention to ensure it’s ready for the task.

How to look after your spare wheel

1. Check the tyre pressure regularly

Just like the existing tyres on your motorhome, the spare tyre’s pressure can decrease over time, especially if it’s left unattended for long periods. It’s essential to check the tyre pressure regularly, at least once every few months and always before setting off on a journey.

Use a reliable tyre pressure gauge and inflate the spare wheel to the recommended pressure, which can be found in the owner’s manual. Keeping the pressure correct will ensure that the spare is ready for use at any moment, and won’t fail you in an emergency.

2. Inspect it for damage

Even though your spare wheel is not in use, it can still be susceptible to damage, especially if it’s mounted on a wheel carrier, or exposed to the elements. Inspect the tyre for signs of cracking, cuts, bulging or any other damage. Exposure to UV rays, heat and cold can degrade the rubber over time, leading to issues when you eventually do need to use it.

Regardless of where your spare wheel is stored, consider investing in a tyre cover to protect it from sun exposure and weather conditions. This simple addition can greatly extend the life of the tyre.

3. Monitor the age of it

Tyres have a limited lifespan, even if they’ve never been used. Most tyre manufacturers recommend replacing tyres after 5-7 years, regardless of how much tread is left. To determine the age of your spare tyre, look for the four-digit code on the sidewall. This code indicates the week and year the tyre was manufactured (for example, 2117 means the tyre was made in the 21st week of 2017).

If your spare tyre is approaching the recommended age limit, it’s time to replace it. Even if it looks in perfect condition, older tyres can become brittle and prone to failure.

4. Ensure you store it properly

Whether your motorhome’s spare wheel is stored inside or outside the vehicle, make sure it’s secured properly. A loose or improperly mounted spare can move around while you’re driving, potentially causing damage to the tyre or your motorhome.

If you’re storing the spare tyre for long periods (such as over winter), ensure it’s in a cool, dry place, away from direct sunlight or harsh weather conditions. Storing it off the ground and on its side (rather than upright) can also help to reduce stress on the tyre.

It’s a good idea to keep it out of the way if possible - if it’s used as a dog bed in the motorhome, or the kids play with it, it could get damaged over time.

5. Rotate the spare

It’s a good idea to rotate your spare wheel with the tyres in use from time to time, especially if you don’t frequently need to replace your motorhome’s tyres. This helps ensure that the spare doesn’t wear unevenly or become neglected over long periods. Also, by including the spare in your tyre rotation routine, you also ensure that it gets some use and that it’s still in good working condition.

6. Check the tools you have

It’s not enough to simply have a good spare tyre – you probably also need to ensure that you have the correct tools to change it! Make sure your jack and wheel brace are the right size and in good working order. It’s easy to forget these tools until you’re in a situation where you need them, so checking them regularly (and putting them back where they live!) is a smart thing to do.

Consider carrying a set of gloves, a torch and any additional tools that might make changing the tyre easier, especially if you find yourself doing so in less-than-ideal conditions.

What to do if your spare wheel is damaged

If you discover that your spare is damaged or too old to be used, replace it as soon as possible. Try not to take the risk of travelling without a reliable spare, as breakdowns can happen when you least expect them.

When purchasing a replacement, ensure that it’s the correct size and load rating for your motorhome. It’s always best to consult your motorhome’s manual or speak to a tyre professional for advice on choosing the right spare.

Caring for the spare wheel on your motorhome may not be the most exciting part of motorhome maintenance, but it’s certainly one of the most important. A well-maintained spare wheel could be the difference between a minor inconvenience and a major headache on your next adventure.

So, before you set off on your next trip, take a few minutes to check that your spare wheel is in top condition – it could save you a lot of trouble down the road!
