Wolverine

Hi All. Need to be sure of tyre pressures on my 110 CSW (almost always
carrying two adults, three kids and two dogs if it makes a difference).
Tyres are 235/85 R16 Mud Terrain. Also have a set of Bronco MT Remoulds
(same size) are they any different?
Need to know ASAP please.
Wolverine.

Mine are 40/42 psi (Goodyear Wranglers)

arrrgrh, not again.


I'd go for about 36 all round, but tyhe book will tell you 28 front 42 rear
or somesuch. 28 is too soft for good tyre wear although it probably makes
for a slightly smoother ride. 36 is fine in the back provided you're not
carrying heavy weight, in which case you need to up them to 40 maybe.

the 28 figure dates back to cross-ply tyres - radials, size-for-size, seem
to run better a bit harder.

BFG AT at 28 35 that lasted 50k is that good or bad ??

Isnt there a formula to calculate pressure; saw one years ago byt cant trace
it ??

Don't think there can be a general formula - all tyre pressures are a
compromise, comfort and ground pressure on the side of low pressure, tyre
life and handling on the side of high pressure, with added complications of
needing to increase rear pressure as load increases. Having the pressures
wrong between front and back can make a big difference to handling.

Placarded pressures on my 110 are 35/35 unloaded at speeds below 100kph up
to 65/60 fully loaded at sustained speeds above 120kph. And take off 15 for
soft ground. (all in psi) Note that these pressures are all higher than the
UK recommended pressures, probably because Australians drive long distances
at high speed in high temperatures on rough roads.

Fellow listers,

took me some time to unearth the formula but finally managed to find it.

QUOTE
1. Take the total weight of your truck, write it down and put an "A" next to
it.
2. Then multiply the maximum weight from the tyre sidewall by four {four
tyres under the truck}, write down the answer and but a "B" next to it.
3. Divide "A" into "B" and write the number down with a "C" next to it.
4. Next divide "C" into the maximum side wall pressure "D", and you have the
correct pressure for your tyres on your truck.

---------------------
The formula is shown again below to help.

Truck weight in lb's =A
Side wall max weight x 4 =B
B into A = C
Side wall max pressure =D
C into D = ideal psi.

With the correct inflation pressure and having been balanced right, your new
tyres will give years of faithful service.

UNQUOTE.

Unfortunately I have not noted from where I have copied it but whoever has
posted it first is to be thanked.
Works very nicely but will work even better if you do it on an per vehicle's
axle basis. So you calculate the front axle's weight as A and multiply by 2
(instead of 4) in order to calculate variant B.

You see our landies tend to be more nose heavy, especially if they are
fitted with winches, bullbars etc.

Take care and hope this helps.

Nice theory - and it doesn't work.

Sorry but that was all I had in relation to tyre pressure formulae.

Take care
