Should you change caravan tyres at five years?

You know that moment when you’re hitching up, feeling oddly smug because you remembered the breakaway cable, and then your eye catches the tyres. The tread looks fine. The sidewall looks… mostly fine. But a little voice pipes up: “Aren’t caravan tyres meant to be binned at five years?”

That question gets repeated so often it starts to sound like a legal requirement, on a par with having a number plate and a jockey wheel. It isn’t. But it’s also not a myth you can ignore with a shrug. Caravan tyres live a different life to car tyres, and the calendar matters more than many people expect.

Should caravan tyres be changed at five years?

If you want the calm, non-dramatic answer: five years is a sensible checkpoint, not a universal deadline.

Some caravans will genuinely be on borrowed time at five years because their tyres spend long periods parked, loaded, and exposed to sun, damp, and temperature swings. Other caravans, stored well and used regularly, can be perfectly serviceable beyond five years - provided the tyres are the correct spec, in good condition, and inspected properly.

The problem is that many owners make the decision based on tread depth alone. Tread is only one part of the story. With caravans, the bigger risk is often age-related deterioration: internal weakening and sidewall cracking that can arrive with plenty of tread still showing.

So the real question isn’t “five years, yes or no?” It’s “what has happened to these tyres over their life, and what evidence do I have that they’re still healthy?”

Why caravan tyres age differently to car tyres

Car tyres typically wear out because they’re used. Caravan tyres often fail because they’re not.

A caravan can sit for weeks (or months) with a high static load pressing one section of tyre into the ground. Over time, that can encourage flat-spotting, stress the casing, and make any existing weaknesses more likely to become a problem. Add in UV exposure on a sunny pitch, winter storage on cold concrete, and the fact that many caravans travel fewer miles per year than the average school run car, and you’ve got tyres that can look “hardly used” right up to the point they aren’t.

There’s also a psychological trap: caravan tyres often come from the factory with lots of tread, and because the van doesn’t do huge mileage, they still look fresh years later. Unfortunately, rubber doesn’t care how proud you are of your tread depth.

What actually fails as tyres get older

Ageing tyres tend to show issues in the sidewall and the internal structure.

You might see small cracks in the sidewall - sometimes called weathering or crazing. Not every tiny mark is an instant death sentence, but cracking is your tyre politely telling you it’s been through a few seasons too many.

More concerning is what you can’t easily see: the bonding between layers, the condition of the cords, and internal fatigue. When that lets go at towing speeds, it can escalate quickly. A caravan tyre failure is rarely a gentle “pull over when convenient” affair - it can damage the wheel arch, floor, wiring, and even the bodywork, turning a simple tyre replacement into an expensive and trip-ending drama.

If that sounds a bit gloomy, good. Not because we’re doing scare tactics, but because understanding the consequence helps you make a grown-up decision rather than a superstition-driven one.

How to check the age of your caravan tyres (the date code)

You don’t have to guess. Tyres have a date code moulded into the sidewall as part of the DOT marking. The key bit is a four-digit number.

For example, 2321 means week 23 of 2021. That’s the tyre’s manufacture date, not the date it was fitted to your caravan. If you bought a new caravan that had sat in a compound for a while, your “new” tyres might already be a year old before you even tow it home.

If you’re doing the five-year conversation properly, you start here. Work out the tyre age, then move on to condition and suitability.

The five-year checkpoint: what to look for

At around five years old (or earlier if the caravan has been stored poorly), it’s worth doing more than a quick glance. Ideally, check the tyres when they’re clean and dry, and look at both the outside and the inside sidewalls - the inside is often where cracking hides.

You’re looking for a combination of evidence, not a single magic sign. Sidewall cracking, bulges, cuts, or repeated slow punctures should put replacement firmly on the table. Uneven wear can point to alignment or suspension issues, but it can also signal that the tyre has been run underinflated or overloaded - both of which shorten tyre life.

Also pay attention to how the tyre feels when you press the sidewall. You’re not trying to do a scientific test with your thumb, but if the rubber feels unusually hard and plasticky compared to a newer tyre, that ageing process is underway.

The part people miss: load rating and speed rating

A tyre can be young, pretty, and still wrong.

Caravan tyres must be suitable for the caravan’s maximum technically permissible laden mass (MTPLM) and axle limits. The load index on the tyre tells you the maximum load it can carry at the rated pressure. If the tyre is under-specced, you can have problems even if it’s brand new.

This is where owners accidentally talk themselves into the “five-year rule” being the main issue, when the real issue is that the tyre was marginal for the caravan in the first place.

Speed rating matters too, but for UK caravanning the bigger day-to-day risk is usually load and pressure rather than someone towing at race pace.

If you’re unsure what’s fitted and what you need, it’s worth checking the caravan plate for weights and comparing to the tyre markings, or speaking to a reputable tyre fitter who understands caravans (not just cars).

Storage and usage: the ‘it depends’ bit that actually matters

If your caravan lives on a sunny drive with the tyres exposed, gets moved twice a year, and sits fully laden with your kit inside, those tyres are having a harder life than the same model stored in a shaded compound and moved monthly.

Regular use is not a guarantee, but it helps. Tyres that roll and flex tend to stay healthier than tyres that spend long periods compressed in one position.

Tyre covers can reduce UV exposure. Keeping the caravan on a hardstanding rather than damp grass helps. So does maintaining the correct pressure even when the caravan is parked - underinflation during storage is a quiet tyre killer.

None of this is glamorous. But it’s the difference between “five years sounds scary” and “I know how mine have been treated, so I can judge them sensibly”.

When five years is a good time to replace

There are a few scenarios where replacing at five years is simply a tidy, low-drama decision.

If you do longer tours, tow at motorway speeds regularly, or head abroad where a tyre failure is a bigger logistical headache, changing at five years can be a form of insurance. Not because the tyre is automatically unsafe on its fifth birthday, but because you’re reducing the odds of a trip being derailed.

It also makes sense if you can’t verify how the caravan was stored before you owned it, or if the tyres are of unknown quality. And if you’ve spotted sidewall cracking, any bulging, or persistent pressure loss, you’re already beyond the “debate” stage.

When it may be reasonable to go beyond five years

If the tyres are the correct spec, have been stored well, kept at the right pressure, show no cracking or damage, and you do modest mileage, it may be reasonable to continue beyond five years with increased inspection frequency.

The key phrase is increased inspection frequency. Past five years, you’re choosing to rely more on condition monitoring. That’s fine if you’re genuinely doing it, not just telling yourself you’ll have a look “at some point”.

Many owners choose to replace by seven years as a practical upper limit, even if the tyres still look decent. Not because there’s a cliff edge at seven, but because time keeps moving and tyres keep ageing.

Don’t forget the spare tyre (and don’t trust it blindly)

The spare is often older than the main set, sometimes original to the caravan, and sometimes hidden where it never gets a proper inspection.

A spare that’s ten years old and cracked is not a get-out-of-jail-free card. It’s a heavy ornament.

If you replace your caravan tyres, think about the spare at the same time. You don’t necessarily have to replace it on the same day, but you do need a plan that doesn’t involve discovering its condition in a lay-by.

Choosing replacements without overthinking it

When you do replace, match the size and specification required, and don’t get seduced by bargain-basement options that look fine in a listing but have a vague load rating or a mystery brand name you’ve never heard of.

A decent tyre, correctly rated and properly inflated, is one of the least exciting upgrades you can buy - and one of the most confidence-building. If you want to feel calmer on the first tow of the season, tyres and tyre pressures beat most gadgets.

If you want a simple habit that pays off, check pressures before every trip when the tyres are cold, and don’t forget that caravan tyre pressures can be higher than your car’s. Your caravan handbook or plate information should guide you, and if you’re unsure, get advice that’s specific to your caravan and tyre rating rather than a generic number from someone’s memory.

A final thought

You don’t need to panic-replace tyres the moment they hit five years, and you definitely don’t need to ignore the calendar because the tread “looks alright”. Treat five years as the moment you stop guessing and start verifying - age code, condition, load rating, pressures, and how the caravan is stored. Confidence comes from evidence, not folklore, and your holidays are far more enjoyable when you’re not side-eyeing the tyres at every services stop.
