Tyre savers or not

What is the life of a caravan tyre? After how long must/should they be replaced? What's recommended?

I have left all my caravan tyres completely untouched every winter on every caravan I have had since 1964. If any of them had flat spots I never noticed when we went out again in the spring. 

Likewise, In fact I don't think I would recognise a flat spot

Yes another vote for that. Just park it up until the Spring.

Five years recommended with seven as a maximum.

Axle stands for mine as the storage ground is small sharp stone, but resting on it's tyres this year as I will have new ones fitted before next years outings.

get a pair of winter wheels and tuck your tyres to bed in the garage for the winter - good security measure too!

Why not use the caravan all year round

But, check the insurance if using winter wheels as not all policies allow them.

I  too use winter wheels as they save the tyres and are a put off fort any would be thief, and  I can't understand why an insurance company would not cover you, especially if you are leaving it on your own driveway. The CC don't allow this I beleive.
