Hi All, This is our first caravan and haven't been away in it yet, although we are booked up for May day weekend and cannot wait. We went to the storage place yesterday to check it over and I made a point of checking the tyre pressures. According to the owners manual, for our model, the tyre pressures should be 3.75 bar / 54 psi on 175 R13 6 ply tyres. To me this sounds very excessive although it must be correct. Is this pressure pretty much the normal on caravan tyres? It's really just peace of mind.
First 54psi is also is the maximum pressure for this size and type of tyre which should have a load index number of 94 representing 1340kg per pair of tyres. For caravan use the tyre manufactures advise reducing this by 10% giving a new maximum weight of 1210kg at 48psi per pair.
Your van at 1182kg sits nicely under this at a pressure of 46/7psi
Hi Degsytroy , my caravan has a mptlm of 1160kg and i run my 6 ply 175 R13 tyres at 46 / 47 psi . 54 psi does seem a bit high to the weight of your caravan .
I know this is unorthodox , but i have towed many thousands of miles in europe over the past 12 years with two single axle caravan 1200kg m.a.w at high speeds up to 75 mph at only 36 p.s.i i have found less bouncing at these speeds. and have endured one blow out in that time.
hi Bicheno how to say without being rude.if your tyres should be 54psi you have been lucky.under inflation is the major cause of blowouts on caravans after age degradation .this is due to the heat build up in the tyre.if your tyres should be 36 psi,then you have been correct with your pressures.if the hand book says 54 psi that is what they should be. on our new van they are only 37psi.checked today and they are exactly 37 psi.
