Changing caravan tyres - before the tread is worn

Caravan tyres tend to degrade and become unusable due to age rather than wear so I recently changed all four of my tyres.
Also had minor issue with ALKO jack and some musings on how secure the security wheel nuts provided as standard with Bailey caravans actually are.

The safe period for changing tyres is 5 years because of the degradation due to principally UV light from the sun, I have seen tyres on a vehicle just 4 years old dry rotted because it spent a good deal of its life in the compound, on someones drive and then in the used car lot fully exposed to the sun. However, this limit can be drastically reduced if the tyre is left in a deflated state so that the sidewalls are over stressed. Conversely, if the tyres are stored in a cool, dry and dark environment (your domestic garage does a good job) then they can last for a lot longer. You don't change your spare tyre in the car every 5 years and they can be used after a lot longer than that. It makes sense for caravans especially, where the use is very intermittent and long layoffs are experienced to take off the road wheels and store them in that cool, dry dark space, leaving the 'van propped up. Taking the wheels off also serves as a significant deterrent against theft.

Thanks for the extra info.

Check new tyres are as close to the current date as possibility. If you have a year old tyre the life starts from the date on the tyre .

Always to do that but often just have to take what the tyre shop has in stock. I think my new tyres are about four months old which bearing in mind they came from India or China is about as good as I was likely to get.

Thanks for your video Dave, I will be checking my caravan tyres soon, I sir pose it would be less drastic having a blow out with twin axle caravan than a single axle caravan, 👍.
