Can anyone advise me what tyre pressures I should have in the following tyres I have on my 280 GE:

Michelin 4x4 205/80R 16xPC Radial.

Wagon is generally unladen and used on the road, thanks in advance for your help!

Front: 32 psi
Rear: 32 psi unladen but if you plan to drive your mother-in-law in the back ans she's as fat as mine you'd better put 36 psi in the back.

8) :lol:

Cheers!

Jesus, do you happen to know what the tyre pressures should be for 460 LWB 300GD on BF Goodrich A/T 31X10.5 X 15 R ?

Thanks
Colin

No idea.

They are not listed in any manual -they were never a factory option-

31x10.5R15 is like a 265/75R15. I would use 32/32 psi and see how the truck feels.

Unless somebody else has a better idea?

Cheers

Thanks Jesus

I couldn't find anything either, I'll try that and see how I get on.

They seem peculiar sizes but I have seen them listed in tyre adverts.

I tried looking up the BFG website but nothing about tyre pressures that I could see, in fact i couldn't find any reference to these sizes either. Is this a continental way of sizing tyres?

Regards
Colin

31 x 10.5R 15 is the imperial/US way of referencing tires.It means 31" diameter, 10.5 " wide 15" rim. It seems to be common practice here as well in 4x4 circles. My G has 255/75-15 which is roughly the same size .The manual says 32 F and R. More in the rear if there is a load.

Thanks very much Roly, that explains a lot, the tyres were on the car when I bought it and I was beginning to wonder where the previous owner had aquired them.

Thanks again gentlemen
