Mostly asphalt 2 lanes. But, I need to go on gravel, dirt, sand and sticky mud in spring, summer, fall. Probably more off road than many, but still 90% or more it's on pavement. Pull a bumper trailer with 10 to 12k about 2500 to 5000 miles a year too.
Here's the Toyo propaganda;
M-55
The M-55 is an all-position traction radial designed to deliver versatility and exceptional mileage with dependable traction on- or off-road. Easily handles rough terrain, mud and snow. Built to handle the most demanding commercial applications
It's not a mudder and not even as agressive as many T/A tires, but it has good reports on the dodge and Ford diesel forums. Some are claiming 70,000 miles a few are claiming more. Looks like most are in the 50-60,000 mile range. The tires are about 50% more than normal tires, but I am getting an odd ball size. LT255/85R16. It's 33" tall and only 10" wide.
Used treadepot.com and ordered Monday afternoon. Last day for the FREE shipping. That saved some where between 48 and 162 bucks (the range on shipping for online bought tires). The UPS tracker says they will be here Friday. Pretty good. No one in town had anything in the 255 size, nor could they get them.
Will post back with info when they show up and after they are on.
Still would be good to hear from a current user...
