Cooper Discoverer AT3
After the BL goes on, I want to put on some 285/75/16's on the Ranger. These Cooper's have caught my eye pretty well. But in that size they are only offered in a load rating E. I emailed the tech guys at Cooper and asked them if that load rating of tire would make the Ranger ride like crap. Here is his response....
The LT285/75R16 Discoverer A/T3 tires is 10 ply rated or a load range E tire. Radial tires do not have the number plies like a bias ply tire does. They are rated 6, 8, or 10 ply. You just need to reduce your inflation pressure for your lighter weight Ranger. I would probably start the tires at 35psi. The tire has a maximum pressure of 80psi, but you can run the appropriate pressure to match your vehicle. The lower pressure should make the ride what you want. Too much inflation stiffens the sidewall and creates a bad ride......
With that being said, what is the dang difference between an E load rating and C load rating? Sorry I don't know anything about tires. I have heard that load range C is the best for Ranger however.
