popotla Posted May 22, 2009 Share Posted May 22, 2009 On my Landrover Defender Td5 County Station Wagon 110 (year 2005) I have just fitted new Michelin LTX A/T '2' tyres (LT 235/85R16 120R). (The treads are different from the earlier LTX A/T.) What pressures (front and back) and FULLY LOADED and NOT LOADED should these be run at? The LR handbook says “rear @ 48 psi” but this seems wrong.

The handbook is right - although most people only use 48 fully loaded as farm as i can tell. I run my tyres at 38 on the back and whatever the hanbook says (28?) on the front. You'll have a barrage of opinions in tyre pressures now, it comes down to personal preference within reason. Rightly or wrongly i don't alter the fronts, just the rears depending on load.

headhunter Posted May 22, 2009 Share Posted May 22, 2009 48PSI in the rear is correct, 28 for the front, although I run my fronts at 33. If the ride is too stiff you can always reduce the rear pressure when unladen by a few PSI. John Quote Link to comment Share on other sites More sharing options...
BogMonster Posted May 22, 2009 Share Posted May 22, 2009 THe published pressures are correct for high speed laden use as otherwise the tyre gets far too hot. Personally I run mine at about 22/28 because of the low road speeds here and the fact that a few psi make a hell of a difference to ride, 20psi makes it feel like a different vehicle not to mention better flotation on soft ground. I definitely wouldn't recommend it at UK road speeds, but if you use 48psi on our roads here you might as well fit concrete wheels. Quote Link to comment Share on other sites More sharing options...
western Posted May 22, 2009 Share Posted May 22, 2009 I run my 110 with 28psi front & 40psi rear [has a lot of recovery kit onboard] try 35 in the rear for normal everyday unloaded use. Quote Link to comment Share on other sites More sharing options...
Phil Posted May 22, 2009 Share Posted May 22, 2009 My vehicle's generally unladen, I inflate the tyres to 28psi front and 35psi rear. Phil. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted May 22, 2009 Share Posted May 22, 2009 I run my tyre pressures 30/32 front and 34/36 rear laden and unladen. Laden could be as muct as 2,400kg in total weight. Ambiant tempuratures up to 40Deg C mike Quote Link to comment Share on other sites More sharing options...
popotla Posted May 25, 2009 Author Share Posted May 25, 2009 Thanks for replies. Reading what mmgemini posted, that seems to be lower pressures when laden (??). I often have the combined circumstances of heavily laden and moderate or fairly severe off-road. So how about maybe 38 psi rear under those circumstances?

western Posted May 25, 2009 Share Posted May 25, 2009 best way is to try it & keep a watch on the way the tyre tread wears, if to much wear on the shoulders then the pressure is to low 7 if wearing in the centre pressure is to high. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted May 25, 2009 Share Posted May 25, 2009 If you load upcorrectly, you shouldn't have a problem. Loading correctly means ALL the heavy stuff between the wheels or over the rear axle.... Somewhere on here is the "chalk" method of finding the correct tyre pressures....I'm sure somebody can find it. mike Quote Link to comment Share on other sites More sharing options...
