Jimbo-TD5 Posted September 26, 2009 Share Posted September 26, 2009 hi all, my discovery 2 has 245/75 16 colway MTs on it, and I dont know what pressure to put in them, they currently have 38ish all round, but for some reason the back tyres looks soft. Is there supposed to be more air in the back?? Quote Link to comment Share on other sites More sharing options...
thebiglad Posted September 28, 2009 Share Posted September 28, 2009 38psi on the front is high I would say, try more like 32psi Quote Link to comment Share on other sites More sharing options...
MartinK Posted September 29, 2009 Share Posted September 29, 2009 I run 30 psi in the front and 40 psi in the rear. But I do carry reasonably heavy loads (and tow a trailer) quite a lot. Works for me. Also have All Terrain's (BFG). Lower pressure worsens mpg... Quote Link to comment Share on other sites More sharing options...
andyjim Posted September 29, 2009 Share Posted September 29, 2009 hi, I have run discos for a few years and normally put 28psi in the front and 38psi in the rear. When towing, I increase the rear to 48psi. I know at normal pressure (28&38) the tyres do look a bit soft, but this is normal and the tyres seem to last pretty well. Hope this helps.

The first thing to do is to read the manufactures figures that are in your owners hand book for the disco. Using those figures as a guide, you can add or reduce the pressures to suit your driving and loads that you carry. For Gawds sake don't read the tire side and then add air till it reaches that figure! You have radial tires, there will always be a bulge in the tires it's normal. Finally, there is normally more pressure in the front tires than the rears because the vehicle is heavier at the front when unladden. BUT don't take that for gospel. Todd.

Hi Todd, Can't agree with your final statement at all. If you look in the book of almost any car you will see more pressure is required in the rear tyres, even though your logic relating to Disco's seems fine, the recommended pressures are (depending on tyre size and weight loaded) 26 in the front and 36 in the rear.

tuko Posted September 29, 2009 Share Posted September 29, 2009 Like I said, don't take that for gospel, but I have ran into this with other cars. Todd. Quote Link to comment Share on other sites More sharing options...
