Define 'over inflation'.

It simply cannot be ignored that over-inflated tyres will transmit more road vibrations through to the caravan, which will have an impact on all the components in the caravan and also on the caravan structure.

The difference in 'vibrations', both in terms of frequency and apmlitude is negligible compared to that from the road surface.

Have you considered what happens to an already over-inflated tyre on a very hot day which will cause the tyre pressure to become even higher?

The pressure rises but as long as the maximum static pressure is not exceeded the increase is taken care of by the manufactures tolerances.

The reason why over-inflating might give better handling is simply the very flimsy nature of some caravan tyres, with very thin sidewalls. Newer caravans do seem to be addressing this better and fitting more robust tyres.

Can't argue that manufactures use the cheapest (and lightest)! tyres they can get away with and they are often therefore minimally specified.

That's why Knaus fitted truck tyres inflated to 65 psi on the Starclass.

The garages just love people like you, it keeps them in Rolls Royces.

Oh dear, down to personal insults to try and prove your point, and a very inane one at that. Personally, that's why I have a Mitsubishi; I only visit the garage once a year, for the annual service.

Perhaps instead you might supply evidence that:

a) frequency and amplitude of vibrations due to over-inflated tyres are independent of road surface in the first instance
b) that such vibrations have a negligible effect on either the caravan body shell or any of the components in the caravan.

Got the will to live back.

Do YOU want to define over inflation?

Then we can continue the argument.

tyre safe are doing work on this now, i was involved in an event with them and took the tyre spec in and photo over the plate as the tyre had been replaced the new ones had a higher load index and the psi should be 5psi more once the calculation had been done
