If you go to Tire Rack and enter your size, you'll get a list of tires. You can then select the tires you like, and click on specs, and see all the sizes and specs.
There are 14 tires listed, open up specs, like for example ... General Grabber AT2, available in
255/70-17, 640 AB UTOG rating, load rated 112S at
2469 lbs. at 44psi, 6.5-8.5 rim width, 10.2 section on a 7.5 rim, 31.1" diameter.
Down below in the chart is the same tire, size
265/70-17, 640 AB UTOG rating, load rated 115S,
2679 lbs. at 44 psi, rim 7-8", section 10.7 on a 8" wheel, just 31.7" diameter.
In 17" tires, about as high as it gets until you go for the heavy duty tires that need like 80 psi and will be hard as rocks on a F150.
I haven't seen many tires with LT designation in last few years. Now they are either Passenger .... or light truck / SUV tires, which get broken down into ... on road summer ... on road winter ... off road / all terrain ... and off road ... it seems.
Not recommending the Generals, just used for example. I have no experience with them.
