Tractor tire wear

Whiskey Bent · Jul 23, 2017

Why do tractor tires wear on the back side of the lug? See it on tractors that are on the highway alot.

hd6gtom · Jul 23, 2017

Don't know why. A lot of time the left tire runs on the paving and wears more than the right tire running on the
shoulder. The long bar - short bar tires of the 80's wore very bad on the highway, short bar wore off quickly
leaving a long space. That caused the long bar to wear as you describe.

The wear on the back side of the lug is caused by the lug flexing on the solid pavement. Think about it. With a lug straight down and the wheel torque pushing the tractor forward. This makes the lug fold opposite the direction of travel. So the trailing edge is what wears. Heavier loads and lower tire pressures make the lug flex be more.

Flex from torque, taller tread makes it
happen even more noticeable. If you look
at things like state mowing tractors
that run on the road a lot but just
drive not tow stuff you will notice they
wear much flatter, also they usually run
more air pressure since they don't need
the tillage traction.

Your car and truck tire wear the same way,you just cant rotate a tractor tire to run backwards.

I've seen only one brand of rear tractor tire that didn't exhibit much wear from highway travel and it's a Continental 18.4x38 radial. Those tires have been on my tractor for yrs during my custom baling/farming operation. Downside is they lack good traction when plowing but I baled a lot more acres than I plowed.

That's nothing, mfwd tires wear like the dickens on the
highway unless you put Michelin radial tires on.

We're on chipseal and my tractor that travels the road all the
time doesn't get 400 hours out of a set of front tires.

Driving in 2wd or 4wd ?

I watched a slow motion video of a tire lug scrubbing as it left the ground on a hard surface. It didn't seem to have much to do with torque but more in the way the lug flexed forward as it hit the ground on the way down and flexed back as it left the ground on the way back up. I'm sure torque from pulling a load would exaggerate it.

Is that for me? 2wd on road, 4wd braking disabled
