Caravan tyres often look fine — right up until they fail. Unlike car tyres, caravan tyres can age out long before they wear out, especially if the van spends long periods parked.
Knowing how to inspect your caravan tyres for wear, damage, and age is one of the most important safety checks you can do, and it only takes a few minutes.
This guide shows you exactly what to look for and when it’s time to replace tyres, even if they still have tread left.
What You’ll Learn
- How to check caravan tyres for visible wear and damage
- How to read tyre date codes to determine age
- Why tyre age matters more than tread depth on caravans
- When tyres should be replaced — regardless of appearance
This guide is suitable for all caravan owners, including first-time buyers.
Why Caravan Tyre Inspection Matters
Caravan tyres carry heavy loads and often sit stationary for long periods. This leads to:
- Rubber hardening and cracking
- Sidewall fatigue
- Increased risk of blowouts
- Poor grip and handling
Most caravan tyre failures are age-related, not mileage-related.
Step-by-Step: How to Inspect Caravan Tyres
1. Check Tread Depth and Wear Pattern
Look for:
- Uneven wear across the tread
- Flat spots from long storage
- Bald patches or exposed cords
Minimum legal tread depth is 1.5 mm, but caravans should ideally have more.
2. Inspect Sidewalls for Damage
Sidewalls are the most common failure point.
Look for:
- Cracks or crazing
- Bulges or bubbles
- Cuts or abrasion
- Discolouration or perishing
If you see any of these, the tyre should be replaced.
3. Check the Tyre Age (Date Code)
Tyre age is identified by the DOT code on the sidewall.
- The last four digits indicate week and year of manufacture
- Example: 3520 = Week 35, 2020
As a general rule:
- Replace caravan tyres at 5–7 years, regardless of tread
- Earlier if stored outdoors or heavily loaded
4. Don’t Forget the Spare Tyre
Spare tyres often get overlooked and are frequently the oldest tyre on the van.
Check:
- Tread
- Sidewalls
- Age
- Correct pressure
A spare tyre is only useful if it’s roadworthy.
Extra Checks for Tandem Axle Caravans
If you have a tandem axle:
- Compare wear across all tyres
- Look for scrubbing or feathering
- Check alignment if wear is uneven
Uneven wear often points to suspension or alignment issues.
When Should Caravan Tyres Be Replaced?
Replace tyres if:
- They’re over 5–7 years old
- Sidewall cracking is present
- Bulges or damage are visible
- Wear is uneven or excessive
Tyres are cheaper than repairs — and far cheaper than accidents.
Common Tyre Inspection Mistakes
- Relying on tread depth alone
- Ignoring tyre age
- Forgetting the spare
- Running incorrect tyre pressures
Tyres can look “fine” right up until they fail.
Key Takeaways
- Caravan tyres age faster than car tyres
- Sidewall condition matters more than tread
- DOT codes reveal true tyre age
- Regular inspections prevent blowouts
