Correct Tire Pressure?

[Rampat]

I just leveled my 2021 Rebel and put a set of Toyo Open Country R/T Trail’s in LT295/70R18. 10 ply tire and load rating E. What tire pressure should I be running? The stock Duratrack’s were 55psi front and 45psi rear.

Your new tires are 1 inch taller than stock but both stock and your new tires are 10 ply. I'd probably stick with the recommended tire pressures of 55 front/45 rear.

There are calculators online that will tell you what pressure to run with non-stock tires, baed on the stock tire numbers.

Thank you! Just did the calculator and it came back with 47psi front and 39psi rear.

Tire pressure will vary based on the tires you are using. There is no one size fits all pressure, or any online calculator that can accurately tell you the correct pressure for your truck. Too many variable from tire construction, vehicle weight, driving style...... The best way is to do the chalk test to find what gives you an even contact patch

For max tire life get a depth guage to monitor tire wear across the tread
