Stop using "one-size-fits-all" tire pressures - a science based guide to the right tire pressure

done. metric units are in.
i'll probably do a section tire size, width and contact patch shape as well. maybe tomorrow.

not the most common size to find, especially if you're up in load index 108 for that kind of load. I don't think you can even buy that tire in the US.

Very common size in the UK, most of the big trailer manufacturers use it, ( Ifor Williams et al). The tyres though are all common trailer brands but usually south Asian manufacturers.

yeah i saw them in europe. i just did a cursory look but i could not find that size tire in that load factor in the us. I didn't look super hard though...

That Clark Kent guy wastes far too much time on here. He must be retired.

Am I reading this chart correctly? With a Grenadier at the 3400kg to 3500kg weight range with the OEM spec BFG 265/70 r17 tyres That I would be overweight for the ideal tyre pressure at highway speeds.
You can’t set an “ideal PSI” on a tyre that’s at max weight is my take ?

edit. To add to my confusion. These tyres have a maximum weight bearing capacity of 1450kg each so well within the max vehicle weight of 3500kg for a Grenadier.
