Tires shipped 2 you had all 4 Carlisle farm specialist in stock, for $450 shipped. They’ll be here Sunday or Monday.Don't know your location, buy miller tire had very good prices when I got tires for my B. The only downside is I got Carlisle for the rear and had to get galaxy for the front due to not being able to get the right size in Carlisle brand. More or less same tread pattern so it didn't really matter. Cheers on yoir new tires can go wrong with a std r1 pattern, you know exactly what to expect with them.
On pavement taking dirt to my neighbors place, I keep it in 2. Actually keep it in 2 anytime I’m not digging.Hey, R1s are the standard for a reason. Yeah they won't be ideal on pavement but it's also unlikely you're going to be pushing on anything hard enough on pavement to spin 4 tires. Usually all the stuff you need maximum traction for is dirt related. I think having 2 sets of tires is a good option. Now being on pavement means a lot less margin for error in the size relationship between front and rear tires for the 4wd system. I would totally avoid using 4wd on pavement unless you start spinning, then put it in 4wd, get that little bit of travel done, and shift it back out of 4wd before continuing. We can only get away with the imperfect relationship between front and rear tire sizes because dirt allows enough slip to make it ok. Pavement will put serious stresses into the system if the front/rear ratio isn't spot on.
as far as scooping gravel when I need to do that, 4wd won’t hurt for a few feet of driving at the pile in a straight line.
