I tow my caravan and its a fair old weight...about 1200kg loaded....the Deli also about 2.8 tonne loaded...thats 4 tonne !
I had a blowout last time driving to Ilfracombe...my tyres were at 40 psi...is this too much...should I let them down to about 28 - 30 psi and let them have some more 'give' in them. Having highly inflated tyres, can they be too inflated for towing such a weight and carrying such a load?

Always ran mine mid thirties towing no probs pulling a twin-axle 1500kg _________________ It doesn't matter where you put it, cos someone gonna come along and move it, and it's always been the same, it's just a complicated game..... |

Hi
If you've got the caravan manual it will give you the recommended tyre sizes and load rating with pressures for the caravan. Ours' run at 51 psi but ours is a heavy single axle caravan so the tyres on it are load rated at 98T, which is about 800 ish kgs each, with Tyron bands fitted.
I run the Deli at about 38 psi rears when towing but having said all that we also had a blow out on the right rear of the Deli whilst towing at 60mph in lane 2 on the M4 and the tyre was virtually unused! - you'd be amazed how tight your backside can grip the seat So these things can happen at any time. HTH
Cheers

Hi notty, to low a tyre pressure can cause the tyre's to get to hot and catch fire. I'd try and ask at a caravan centre, they should know. I drive an HGV and my truck's tyre's are about 110psi _________________ 2nd gear low and go go go!

Hi
I forgot to mention that we don't carry passengers and most of the luggage is in the caravan so we don't have to run at too high a pressure. It also depends on the size of your tyres ie ours are 235/75 x 15.
Cheers

45 psi Better check your manual. Deli tyres according to my manual should be around 32 psi. I know a lot of people run more but I've read somewhere that if tyres are way off manufacturers recommendations that it's a possible mot failure and/or illegal and insurance won't pay out. Worth checking IMHO _________________
