I need to put some tires on a MF 12, the old ones don't hold air. Original tires were 23x8.50-12, what sort of replacement tires are people installing? I think IamSherwood put some 26x12-12 lug tires on, are they tight against the fenders, or are they a good fit? And I've noticed that current tires aren't exactly truthfully sized, they seem to "shrink in the wash" if you know what I mean.

Thanks
Howard

Howard, depending on what attachments you have and what you plan to use the tractor for will help in getting a tire size. Have you thought of tubing them? Much cheaper. I have mostly 23X10.50's on my GT's. The GTV/16 has 26X12's but I don't have a mower for it so don't' have to worry about issues of the deck hitting the tires.

Deerstone 23x10.50x12 AGs are a good fit. Seem to be the same height as the 8.50 turfs.
Yes Tire sizes are different today. Carlisle seems to be the only Mfg. that maintains the correct dimensions.

Thanks for the suggestions guys. After thinking it over, I'm going to "invest" in $20 tubes and save the $100 per tire for engine repairs if needed. It's just hard to move the tractor around without good tires. Hopefully the tires aren't dry rotted to the point I can't tube them.

Finally put some "New To Me" tires on my 12 G. I was minding my own business a few weeks ago and a yard sale jumped into my path, and there were some used ATV tires just the size I needed. They are 25x10x12. I've wanted to try a tire this size, but wasn't willing to pay a lot for something that might not fit, but these tires I only paid $15 for the pair. So I mounted them.

As you can see, these tires are quite a tight fit, requiring the removal of the guards above the step. I think if I decide to keep these tires, I'll probably fabricate something to go there. Otherwise, not too wide, not too tall, and they look good. Today, I chose not to go to a plow day, and a neighbor asked me to plow THEIR garden! I said "YES" because I wanted to see how well these tires performed. The baseline tire I am comparing these with is a standard turf tire, loaded with 50 lbs water per side, with chains. Those tires work well. Regular turf tires loaded do not do well. The ATV tires had NO additional weight and were simply inflated to the recommended 5 lb pressure. I was pleased to note that although there was SOME spinning, I could mostly stop it by shifting my weight to the spinning (Uphill) side. I bet they will be absolutly great once I add some water ballast. Wheel Tire Vehicle Automotive tire Plant

Is it easy to add the water to the stock MF tires? I've read about it but never had tried it.

Good score on the tires, even if they are worn. Most ATV guys change their tires when they get down to half tread, which usually starts out at around 1" tall. On our GTs the ag tires start at 1/2" tall tread. Used ATV tires are a way better investment than new ags for sure. Of course new ATV tires are even better, but expensive sometimes..

I use a cheap pump sprayer like you use for spraying pesticide. Once you pull the spray wand off the hose, the hose is the right size to just slip over the valve stem. Remove the valve core, slide the hose over the valve tube, fill your sprayer with the mix of your choice, put the pump lid on and pressurize. Refill the sprayer as many times as needed to fill your tire. The good part is that when you release the pressure on the sprayer, the tire will burp air into the sprayer, then it's ready for more fill. I usually fill till it won't burp any more, then add one more gallon. That maximizes the amount of water in your tire.

I had been looking at ATV tires, but most of the used ones were just outrageously priced, completely worn out, or Both! This set had a good combination of wear and price so I felt I could afford to take a shot at using them.

I decided to do some work to the 12G today. During the short time I've had it, the wobble from the rear hubs has gotten worse, to the point I could easily rock the tractor too and fro on it's wheels. I decided to repair it by drilling a hole in the center and tapping it, in the hope that putting pressure on one side would hold the other side of the hub tightly to the shaft. It may be that two screws, one near each end of the hub, will work better, but for now I needed to know how difficult it might be to drill and tap the holes. Here is one side completed, and I'm happy with it so far. Perhaps after I've driven it for 30 minutes I'll be less happy.

I've forgotten exactly, but it was in the middle of September and it was around Charlotte somewhere- east, perhaps a little north. I truly wanted to go, but didn't think I should spend the money and the time to get there.

Ok, thats the one I was thinking about. The club im in, and my avatar, put that show and plow day on. It was a pretty good success considering it was the first time for that event. I think 15 guys showed up to plow, and the dirt was somewhat near a river so it wasnt too hard to handle with the clay. Maybe next year you can make it down. Shows are wrapping up around here. Just Denver and Arden left. You going to either of those?

Well, the show in Denver was this weekend, and the one in Arden is this coming weekend. Its my second favorite show of the year, after the big one in Denton. The Arden show has something for everyone and plenty to see and do. TONS of vendors selling parts, junk, and flea market stuff. Im going up and will probably stay for two days. Here is their website: http://www.applecountry.org/
