3/4 Ton AT Truck Tire?

Thanks for posting this, and the chalk test is still relevant, to your point when done correctly, to confirm equal application of pressure to the tire and to identify potential suspension issues on a specific vehicle.

The entire industry has settled on the methodology in that document for correct pressure and not a single manufacturer mentions a chalk test anywhere. I have used that document for every set of tires I've bought that wasn't stock size for the past 15 years and all have worn perfectly if rotated correctly and driven on good shocks.

For my HD trucks, I do make a little chart in my phone of the pressures for every 500# above my empty pressure so I can adjust when I carry a load. That comes in handy for sure. Daily I run the pressure for my empty weights plus a little so the truck rides good and wear is good also.

That document is also crucial when choosing a new tire size if ride quality is important to you. You can often choose a slightly different size with a higher max load index at the same or even less max pressure allowing you to drop your tire pressure from stock significantly increasing ride quality. This is the case for most 37x12.50s as well as ~35" diameter LT-metric tires in 285 and 295 widths on 18 and 20" wheels compared to stock sizes. You can often drop 10-20psi and get the same load capacity as stock tires and pressures.

Cooper Stronghold AT 10 ply tire is a really good tire. My son has these on his 2019 Dodge Ram 1500 and they have worked very well for him. I have the Cooper S/T Maxx tire on my Ford F150 and have been very pleased with them but on my next set of tires I'm thinking that I will go with the Cooper Stronghold as I think it might just be a tad bit better. Cooper Tires have performed very well and I like the USA Made fact as well.

Re: the chalk test, what I'm saying is that after you figure out your proper inflation using the tool you provided, especially in an older truck that hasn't had recent maintenance on shocks, tie rods, etc..., it doesn't hurt to run a chalk test to see if there is uneven wear. Tires are expensive, and its better to figure out wear issues early vs. later.

Look up the "chalk test" on Google. I watched a couple YT videos the other night, and doing this test will help you get your tires dialed in at the right pressure and may help you identify and diagnose any suspension wear issues that could be causing premature tire damage.

This is the right way to figure out the correct pressure when you don't run stock sizes or your weight varies a lot. The old school chalk test might work but it could just as easily be incorrect.

Just do the math. If your size isn't on there, email BFG and get the chart for your tire. But this chart is consistent across brands for same size and load index tires.

I will do some research! Thank you, gentlemen.
