I just purchased a 2000 Diplomat with 1 year old LingLong steer tires 275/70R/22.5. Can anyone tell where to find a tire inflation/weight table for this brand? I have googled but could not find one? Can I use the inflation table from another manufacturer? I have a Firestone and Goodyear inflation table and for this size tire they show the same pressures for the same weight. I would like to get a couple of years out of these tires before I replace as I have a bunch of other things to address with a higher priority.

Hi tdb8254,
Go to Truck & bus radial tyre direct from China (Mainland)

This is the manufacturer's web site. I see no inflation table. However, scroll to the bottom of the page and try contacting the supplier/distributor. The size and load range of the tire are both important for determining PSI for a given weight being carried. If the tire is DOT certified for sale in the USA gut feel says inflation tables for the same size tire and load range should be the same PSI. However, I'd make the attempt to contact the distributor and manufacturer.

They have over 3K tires to sell in the truck tire category. There is no search feature. I went through about 10 pages and did not find your size.

My Michelin tires are the same size as yours and are a load range "J"

I think we both went down the same path with no luck. I will try to contract the mfg or distributor to see what I find. I have looked at the same size in Goodyear, Firestone and Yokohama and given my weight I would use 90 lbs. Since I had no other info I am running at the max on the tire sidewall which is 120lbs and the ride is awful. Will be dumping the original Monroe shocks and putting on 8 new Koni's next week. With the correct tire pressure and new shocks I hope to soften up the ride so my fillings don't fall out on every bump in the road.

My Michelin's are the same size as your tires and load range "J". My rear axle is at GAWR (20K) and I run 90-95 PSI in the rear tires. The front axle is at 11.5K and I run 100 to 105 PSI in the steer tires.
