I have just had the same, the guy next door to me has a motor home with tyres still on from new 10 year, he does not have to have his tyres replaced, nothing wrong with them.
Our van tyres are 5 year old or will be in November,and according to service guy, I need to change them then. At the service the age of tyres was noted on the service sheet, and he said speak to your insurer, its a grey area, 5 or 7 years, our tyres are in better condition than the ones on the Motor home. Waiting for insurance to get back to us.
Theres no set life for a tyre. The vast majority of car/light van tyres will be doing enough mileage to be changed before they are 3yrs old so from that we can deduce that manufacturers won't really have much interest in designing tyres to last much longer than that, so the suggestion to change caravan tyres after 5-6yrs is sensible.
About the worst possible life a tyre can have is to be stood still for weeks/months with weight on one place, out in sun & then suddenly driven at motorway speeds for 100s of miles. Its nothing to do with insurance, provided tyres have legal depth tread & no sidewall damage then they are legal.
Its just common sense. Caravan tyres can & do fail at motorway speeds & one reason is that they degrade through age. A blowout is caused by failure of the carcass, the bit you can't see, not by the exterior rubber which may still look in good condition.

Your neighbour is a mug I've just replaced my 9 year old rear tyres which appeared perfect. Fortunately, I got a puncture and, when the tyre pressure dropped, the cracks in the sidewalls were very clear - both rear tyres changed and the dates of front tyres checked.
