Round ones!
Anything but michiblows! I like Cooper and Toyo personally......some like michiblows.......I'll put the XDE M+S on the rear of my dumptruck.....those have be ok, not sure what the new version is.... that is another day and worry!
I'm running a Discount tire right now on my C2500. 60K warranty, $125 plus balance etc for a 245-75-16. An SUV mild AT tire. Dry and rain wetted roads are fine. Not great in snow ice etc. Do the job! Carry loads well too. Should have not issues getting 60K out of them.
Also get ones that have proper traction for YOUR usage, not mine!
