Combine drive tires

mudcreek183 · Jan 9, 2012

I have the chance to buy two almost new drive tires for my combine 95% tread left on them only problem they have a vulcanized boots it the side any thoughts on them?

Since they are operated at low speed and pressure, and if the boot was properly installed, they may very well outlast the combinel.

I'd be very leery of them. What size tires and how much weight will they carry? Is it a top-heavy combine that might tip if a tire blows? An 8 or 12 row cornhead and 300 bushel grain tank on a 25000 pound combine will put a lot of weight on the drives. A 2 row head and 70 bushel tank on a 3500 pound machine is a different story. Look at the weight rating of the tire and the weight of your combine with head and full tank. I'd guess a booted tire can only safely carry 1/2 of what it's rated for. If it blows out when it's on the downhill side on a steep hill you could end up in big trouble.

I have seen several drive tires blow on combines, once while traveling down the road, and there was no damage with any of them but when they blew the rim hit the ground in about a half a second. The one that was going down the road almost hit the ditch but he got it stopped in time. It made the tire changing job a little tough though. Jim

Because of the weight they carry it is usually considered to not be a good idea to run boots in the sidewalls of combine tires. Tractor tires yes but combine tires no.

Thanks for input I didn't think they would any good.

Sorry for my ignorance, what are boots, why would one use them (or not)what do they look like? Never heard of them before... Thanks for explaining it! Ralph.

Ralph, boots are a "vulcanized patch" used to fix larger rips, cuts etc. where regular repair will not suffice...they are often used on the sidewalls without which the tire would be useless...I have seen them hold forever or for very short durations where weight and/or speed were involved...common sense usually will dictate whether they should be relied on or buy another tire...Jim

When I was a little boy, our old MF 300 damaged a front tire. It was going to be a while before the new tire came, so they put a "shoe" in it to get by. The patch was actually bolted into the sidewall. It held a few days, until one day while unloading the shoe blew out. I happened to be in the cab with my dad at the time...as a little boy it scared the !@#@#$ out of me!!!

He was able to get a "loaner" tire and wheel off another combine at the MF dealer while he waited for the new tire to come. A few days later, the old 300 burned up in the field.

Long story short, I would be leary of a booted tire....
