Front Tyres Wearing On The Edges?

mikefoxo

My fathers 4wd has tyres that are wearing on the edges rather than over the whole tyre. It's on the outside edge of each tyre. Dad seems to think that by adjusting the tracking it will cure the problem. I however think it's "road camber" https://en.wikipedia.org/wiki/Camber_angle Anyone know what the real story is and if there's a solution?

Check the tracking and if it's OK then another solution is to swap the tyres to the opposite sides so that they will wear on the other edges then.

Is the correct air pressure in the tyres?

orm0nd

out side wear could indicate that she's toed in

Bring her in and get her tracked. They'll be able to sort tracking and camber as necessary. It's money well spent. We're only guessing here as to what the problem is. Wear in any of the suspension will throw tracking out

And of the course the thing that's free, lads never bother with -putting a breeze in them!! Correct tyre pressures usually on a plate under locking latch on b pillar on drivers side.

What tractor in it?

I'm guessing either a Zetor or a Valmet.

It's a MF 4225

It's been like that since we got it 6 years ago. It worked in a council cutting parks so I'm guessing it would have done a fair bit of road work? We've pumped the tyres since we got it but I'll admit I don't know what the correct pressure should be.

Would it really be the tracking that's the problem? I guess the problem is that the top of the wheel is "leaning out"? Would altering the track rod correct this?

Carry it to the tyre centre get it tracked.
Lads are always saying oh the road wears them that way that's pure ****e.

Sure the wheel in twards the ditch would wear on the inside if that was the case and so would the back ones

Try to figure out if it was built in France or banner lane. As if it's France then the front axle would be set up for the wrong side of the road as in the chamber angle.

A tape measure will quickly tell you if its tracking that is the problem, one can also track it with a tape measure. It will be good enough, lets not get carried away as its not a formula 1 car.

some new yokes are out there with the tracking out by a couple of mm which is enough to make the tyre wear uneven

Its possibly the brakes. With the 42 series massey 4wd, when you hit the brakes, the 4 wd dif automatically engages, so you have 4 wheel braking. Problem with this is if you try to turn as you have your foot on the brakes, as the dif is engaged it causes tyre wear. Even if you take your foot off the brakes the dif stays engaged as it has locked up due to the tractor turning and will not release till you are driving in a straight line again.

The solution is to take the tractor to a garage an have a switch installed which will disable the 4wd dif locking when you touch the brakes - but this means that you only have 2 wheel braking. Just rem to switch on the 4 wheel braking when towing a heavy load.

We had this problem with our Mf 4255 , and the dealer put in this switch which solved the issue.
