Sticker on side of my new caravan with 184 -14 tyres 3.5bar
ill keep them between 2.8 and 3.5. Another question, what do I look for on the tyres to see if they are bad? Mine have good tread left, but is there something else I must look for?
Look for nails and the like that may have pierced the tyre, the tyre may not necessarily be going flat so you would not know it was there unless you checked. Look for fine cracking on the edges and sidewalls these often indicate an older tyre. Look for uneven tread wear which could indicate that the tyres are out of alignment, although I am not sure that this would happen on a caravan very often. Check for cuts from sharp stones mainly on the sidewalls especially if you have been travelling on unmade roads. Always carry an inflated spare for the van and also those cans you can use for inflating and sealing tyres. Use the 4x4 ones. Another inportant thing is to ensure the pressures (even if they are not 100% correct) are the same for both tyres, uneven pressure could lead to instability. Also never use a retread on a caravan. Many years ago my father was told that retreads must be used often and since a caravan stands a lot they must not be used.
Have a look at the caravan specs near the bottom of thios website page, tyre pressures are given for the various caravans and it is mostly 250kpa.
I did try and ook at the specs, but they are so indistinct, I cant read them, and even if I print them, you still cant make out whats written.
I suggest you also make sure what the maximum inflation pressure of your tires are. If it's not to be found on the sidewall, you can obtain it from your nearest tyre dealer. Do not exceed that spec.
My recommendation is that you remove the wheels from your caravan and then roll them slowly while looking into the tread grooves and look for cracks that might be there.If so discard immediately and fit new tyres , all the other rules apply ,ie cuts ,nails etc. When doing this ensure that the tyres are pumped to your max towing pressure so as to expand the rubber.
A good pressure for a caravan tyre is between 2.2 and 2.5 bar, very much a function of the type of tyre. The suggestion of 3.5 bar might be bad advice - most caravan and "bakkie" tyres such as the 6-plies on my caravan (Dunlops) have a MAXIMUM pressure of 3 bar according to Dunlop. The user manual says 2.5 bar.
Had a similar van and pumped the tyres to 2.8, spare to 3.2 and the towcar, a Ford 3.0 Saphire back tyres to 2.8 and front tyres to 2.5
All tyres were radial ply tyres, not the bakkie type
Thanks for all your help guys
I have not experienced any problems yet with any tyres on any of my vans. When i buy a van I normally take the tyres off and have them thoroughly inspected. The last van I bought, I found that cracks had developed between the grooves. So small that they could not be seen with the tyres on the van. They looked almost brand new. The van had been standing for a long time and was in immaculate condition and one would expect the tyres to be as such as well. when they were removed andclosely inspected it was only then that we saw the cracks.
A very important factor in connection with tyres, is the load rating. Make sure your tyres are commercial or bakkie tyres. Tyres made for cars do not last on caravans!
