tires 1990 classic

[MontrealRR90]

Land rover specefies 18 psi in the fron but 38 in the back. I now have BF mud 245/75/16
should i change the tire pressure because of the tires? what are you guys doing?

I would change the air pressure, run 30 plus in front and 35 plus in the rear based on the ride. More air will give you better tire wear and gas mileage.

18? I think it's 28 If I Recall Correctly....on my 245/75/16 MT/r's I run 32 up front and 38 out back.

Sorry I Mean 28 And 38 !

HOW ABOUT FULLY LOADED FOR AN EXPEDITION TOOLS AND ALL CAMPING ECT?

 

[Iron Boots]

easiest way is the chalk test


run a thick line of chalk across the tread area. Drive straight ahead for 20 feet or so on pavement....see where the chalk is worn off...just the middle, too much pressure, just the sides, too little pressure.

I'm running 40 psi front and rear with BFG MT 265/75/16 on my 92 RRC.

i think it's a matter of personal preference... i do 40 front/40 rear on my 215/85 michelin xps.
and how loaded your vehicle is. or if it comes down to comfort, might want deflate a bit. depending on each tire's rubber and tread design, there is a comfort zone or a psi range that is appropriate for that particular tire.

i'm sure there are spec sheets avail from the manufacturer giving you a range that is suitable.
