Front Tire cupping

[Billrog]

My backhoe has always wore the right tire more that the other from running on the hwy in 2wd my tractor that seldom ever sees hard surface wears evenly.

Drive slip ratio may be off. Fronts are skidding because of rolling radius mis-match. Easy to check.

I can take a little bit of extra wear, but this is a lot to me. I have a CAT 416 4x4 backhoe and the tires are 60 percent worn, but show nothing like this. I'm really starting to think that the tire came off another tractor.

Tried measuring the toe in and think its close to what it should be. To get a better reading I plan to hang a 2x4 across the middle of the wheels, and then measure from them. Currently doing some other repairs/checks

You've had 2 members and your dealer tell you it's from running on the road and normal from their own experience. Seems like that's the answer.

Even the dealer said it would do it to both tires (just more on the right), so I'm not convenience yet. If this was the case then to me a real bad design. The tire is about worn out when it gets to about 50 % on one side. So at 50% wear you have to buy 2 tires because one is worn out and the other has half its life left.

Left one might have been replaced due to damage so it is newer and in better shape. More severe road wear is usually from a 'loose' front end. That wobble really gets going at road speed. If its bothering you, why not swap sides of the 2 front tires?

It's also quite possible that the previous owner ran it for a extended period of time with it improperly inflated.

I'll do more research and may swap tires. Also going to mark the tires (front and rear) then drive it in a straight line to see if there is a rotation issue as zz mentioned. Have a bunch of other things to do getting the tractor ready for working. I don't really see how a tire only wears the complete tread off one side and doesn't even get much if any of the other side. The treads over lap in the middle, yet the inside tread looks fine

The tractor has been turning to the left a lot more then to the right on a hard surface with a load in the bucket and/or at high speed.

Definitely an odd tread wear pattern. And could be something very different causing such wear than what has been suggested thus far.
