245/75/16 tyres

Hi I'm now the proud owner of a 97 V8i Disco which is shod with 245/75/16 BFG Long Trail tyres. This seems to be the largest tyre that can be fitted without modification and it does seem rather close to the bodywork. This size is not listed in the handbook so I don't know what pressures I should use.

The BFG's are prefixed LT before the size 245/75/16 (whatever the LT means?) but the only reference to pressures on the sidewall is for the max load which is 1380 Kgs at 80 PSI cold!!

There is no way I'm pumping these up to 80PSI

but then I'm sure each wheel is not carrying 1380Kgs each

Without a weighbridge I can't tell what weight I have on the front or rear tyres and BFG wouldn't have known what load these tyres would carry on each vehicle model when they moulded the tyres. The correct pressure must surely be related to the weight they are carrying?

The handbook has significantly different pressures for the front and rear tyres in both the 205 and 235 sizes specified, so presumably this would also be true for using the 245 section.

Has any body actually got a recommended pressure for this size?

Does any body have a clue on this one? even helpful suggestions appreciated.

LT means "light truck". This tire has a heavier sidewall and higher load rating than a standard passeger car tire. They last a long time on a Rangie, but can be harsh on the road. Don't pump em up to much. 32 ish psi.

id put about 32ish in there aswell cause its good for on and off road but you can pump them up to about 50psi on the road and you'll have better fuel consumption aswell
