You can calculate the actual PSI using the maximum load/maximum inflation information embossed on the side of the tyre and the axle weight on the main vin plate. It will probably be in the low 20s psi. My 97 load index all terrain work out at 21 which looks about right from experience unfortunately I have tpms and it gets very upset with me if I run that low even though it improves the ride quality.

Thank you, will give it a go but as you say tpms is a bit moody when you go that low. however very useful and noted.
Cheers Ken.

The goal here is presumably to get the pressure correct for best tire life, and if that is the case, it is not going to be determined purely by the tire's load rating & pressure, rim/tire width and vehicle loading are also factors to be considered.

Start with the recommended pressures and adjust using the chalk method.

Find a quiet stretch of straight road, and using the chalk, mark a wide band across the full width of the tread on each tire, drive the vehicle in a straight line for a short distance and then take a look at the chalk marks to see where the chalk has rubbed away....

If it's the middle of the tread, the tire is "crowning", either because the pressure is too high or the tire too wide for the rim, if it's both inner & outer edges of the tread, either the pressure is too low or the rim too wide, if it's one edge, either inner or outer, you have some sort of alignment or suspension issue.

Adjust the pressure up or down to get even "wear" or displacement of the chalk.

I suspect you'll find the pressure using the "chalk method" very close to Suzuki's recommended pressures.

I've been running that size BFGs for 9 years, now on my 3rd set. I run then at 21psi most of the time (mixed road and off-road) but put them up to 24 for longer road trips. Wear is always even and tyre life is exceptional. I tend to sell them after around 30,000 miles with 6mm of tread left.
