tyre pressure question

[sallybw]

I wonder if you can help me. We have a 1995 Europa 500ek caravan and it we are trying to find out what pressure the tyres should be. We have looked in the handbook and it does not say. I think the tyres are 175 type(if that makes sense) and was wondering if anyone could assist us in either giving us the tyre pressure levels or pointing us in the right direction.

Thank you in advance

In the absence of information in the handbook, I think call or email to Bailey should prvide your answer.

hi sally
it is possible the tyres on your 1995 van are not the standard ones, as a van of 16years old will have had the tyres changed several times by now. note down all the writing on the tyres ie size speed and load ratings also the MTPLM of the van I am sure with the figures to hand the correct pressures can easily be arrived at.

thanks for the reply, I have noted all the writing on the tyres so here goes
Enduro Radial
Max load single 780kg at 450KPA
1608lbs at 65PSI
Max load dual 690kg at 450FPA
1521lbs at 65PSI
Load Range d
175R13 C
97/95N
8 Ply Rating

I have no idea how you can get the tyre pressure from that information but please let me know if you do as we are going away tomorrow in the caravan and would be nice to have it sorted

MTPLM is 1260

May I take it your van is a single axle. If so, your tyre pressure should be 52psi. If you want the mathematics, this is it. Take the weight of your van and multiply it by the max pressure marked on the tyre. Divide the answer by the maximum weight which is marked on both tyres.

 

[sallybw]

Wow, thank you so much John. Thats great. I shall also write it down somewhere so it will never be forgotten

hi sally
sorry I did not get get back to you been out all afternoon trying to sort the van brakes out cars still in bits I bought the wrong bits DOH??? had to use the bus double DOH???

anyway back to tyres you have allready been given the correct information thanks to john it is 52 psi. allthough I use a different formula the answer comes out the same ie
mtplm 1260kg minus noseweight 75 kg = 1185 axelweight 175R X 13C load index 97 @1185 kg = 52psi

ps if you get some of those very small stick on numbers sold in stationers you could put 52 on each wheel arch then you won't forget the pressures ever

Two questions if I may...
1. How do you work out the tyre pressures for a twin axle - half the answer?
2. How did you use the load index to get the tyre pressures - is there a table somewhere?

Thanks

The load index is the number that comes after the size details. In the above example 175R13 C 97/95N it is the 97 (for a single axle, 95 for a twin). If you Google 'tyre load index' you'll find lots of charts which give you the maximum load corresponding to each index number.
The tyre pressure for a twin axle is calculated the same way as for a single although, of course, you have to halve the total axle load, but the pressure won't be half because the tyres will probably be different.

In the case of a load index of 97/95, the 95 has nothing to do with 'twin axles', 'duel' means it's for use when two wheels are fitted to the same hub, ie, a single axle pickup truck with four back wheels.
The tyre pressure calc for T/A's with four tyres is, add all the tyres max loads together, ie x4 instead of x2, then divide a single tyre pressure by this total and then x van weight
