Front Tire cupping

[AllDodge]

Have a new to me tractor, its a Kubota M9540HDC24.
Been going thru what it needs and have not used it much. Has electric PTO and 4x4 engagement. When the break pedal is depressed (stopped and in neutral) the 4X4 symbol on the dash lights up, don't know if that means anything

The right front tire has some bad wear on the outside tread. Used a level against both front tires and both seem to have about the same pitch. It could be this tire was taken off another trackor before I bought it, but guess it could be something else.

I've looked several times - back/forth. To me it appears both front tires have just about the same amount of wear. So do the rear tires. Check your owners manual regarding that 4X4 symbol or call the local Kubota dealer.

I do understand that its hard to see 3D with a 2D pic. As the tread wears away it gets wider. Note that the tread on the outside is wider then the inside, and its only the right front tire. In the other pics, my finger is not quite the tread that remains on the outside, yet the inside is much higher

Took your advice and called the dealer, its not in the manual that I downloaded. Says the electronic 4x4 does do that when applying the break to make sure all 4 wheels are breaking.
Also the tire wear is part of it if its run on the road, but could also be that the toe in may be a bit to much

Yes, from the wear you are showing on that front tire tread, something is definitely out of spec. on that side. If it were only from running on hard pavement, both front tires would have the same wear pattern.

Recon I'll break out the measuring tape

How about air pressure in both tires and could there be an issue with the right front tire not turning freely?

It may have come off another tractor before you got it, I think I may swap the tires from left to right and see if you notice wear happening on the right again. I don't know if it is possible that the right wheel is locked in 4x4 and the left not. ..

Road use, even in 2wd will cause the right front to wear more than the left.

Will check pressure but every time pressure is low on other equipment I see wear on outside edges

Swapping would be worth a shot

Even a 2wd, ?
Have looked at several 9540's over the last month and some had tires worn out on the front and they were pretty even wear. All of these where not electric 4wd
