M Tire Help

Postby JBall8019 » Tue Nov 01, 2005 9:14 am

Hi Guys,
I will be fixing a flat tire on the M this weekend. I think a nail is the culprit for the failure. Can tractor tires be fixed much like automotive tires with a patch and plug? or would i be better off in the long run taking the tire to a Ag service shop?
Thanks,
John

Most likely, the tire has a tube in it. The tube can be patched and if necessary, the tire can be booted to prevent further damage.

If you can't fix it with a hammer, you've got an electrical problem.

BD,
I dont think there is a tube in it. What is booting a tire?

It would be very unusual, if not impossible for a 38" tire to not have a tube in it. My M has fluid in the tires and they are very heavy... heavy enough that I don't care to try to load them to take them to a tire place. Even though I'm nearly 71 and disabled, If I needed tire work, I would do it myself. The only question is how long it would take. (I rest a lot)

You may be surprised to learn that aside for their weight and the fact that the beads can be rusted in place, those big tires are actually easier to work on than smaller tires are.

A boot is a large reinforced patch for the inside of the casing.

John, are you working with a front or rear tire?

BD, its the rear left tire, and the rear tires are fairly new. my friend that brought the M over told me that he thought that the tire didnt have a tube when he got them replaced. I have never replaced a tube in a tractor tire before so i hope this will be easy :). I hope there is a tube in there because i can patch it myself. hey George, i am glad that you are still able to do the work yourself. I am 32 but i like to take alot of beer and smoke breaks in the barn!

John, the nice thing about working rear tires is that you don't have to remove them from the tractor. They are easier to do while still attached. Just make sure your tractor is well supported. Once you get the bead broken the rest, as George said, is easy.

I just removed a rear tire on the Cub last week and replaced the tube. I find it easier to do the job while leaving the tire mounted on the tractor. I picked up a nice 36" tire iron for 5-Bucks so that made the job much easier. I also did a 15" front tire repair 2-weeks ago and as George said, The bigger tires are much easier to dismount and replace than the smaller tires.

You can tell if a tire has a tube by the way the valve stem comes through the rim.

On tires with tubes, the tube has a "cone" that screws on from the outside, which holds the valve stem in place. Usually a plastic or rubber "nut" that is somewhat cone-shaped. I don't think that M's were designed to be tubeless, but on the bright side, big tubes patch easier....
I bought a bead breaker and 2 spoon irons from Gemplers....work like a charm....I also bought some "goop" which turned out to be nothing more than condensed murphy's oil soap. So, I would save the money on the goop, and just buy a bottle of murphy's. It does lubricate the bead some, and make getting the front bead loose much easier, IMO.

I forgot to mention I had to take the tire & rim off first to break the bead. My bead breaker is a 5-foot long 1X6 flat length of steel that I place one end on the tire close to the rim and then drive My truck up the steel on to the tire and the weight of the truck breaks the bead loose. If that dont work I use the outrigger on My Backhoe to break the bead. I use soapy water on the beads for ease of remounting tire on rim.

Hey Guys,
thanks for the tips! i was wondering how i was going to break the bead, i hope harbor freight has something useful. I was going to use an old brass hammer and some wood.

If you have a large C-clamp it makes a wonderful bead breaker.
