Remove no-flat tires from wheels

Jerrycpp · Dec 1, 2021

I have two worn out 23x8.50x12 no-flat turf tires on my PM-400 Gravely, and want to replace them with pneumatic tires. What is the easiest way to get those tires off the wheels? (Gravely wants over $200 each for the wheels, and they are different than all others I've found.)

not for sure but if there foam filled i would suspect maybe you might have to use a saw and cut them off.

They went on the rims so they should come off with regular tire spoons. If not, use a sawsall like pinball said.

I do not know where you are but I am certain I would have like new used here in Tennessee $45.00 each .

pay now or later, the time has come, now you know the rest of the story about putting garbage in tires.

What is the model number on your PM400?

Mine has original rims and tires and they are regular tires.
The rim does have an extra ridge between where the bead sets and the ridge is just inside the tire bead.

Does yours have air inside or foam? Or some internal rubber or plastic donut?

Partstree shows the rim with 23x10.5x12 tire and valve stem for $232.

P.S.
Just went out to check mine, it has 23x10.5x12 tires. Maybe yours has tires and rims from another machine. Or your tires were mounted on the original rims.
The picture of your tires does look like a narrower 8.5 on a rim built for 10.5 tires.

You can mount up rims and tires from a JD or even a Cub Cadet or most any five lug garden tractor. Just check the offset and center hole size.

I am not familiar with the term no flat. I had the front tires on my loader tractor filled with foam ( too many flat tires). It was made clear that when the tire did wear out - I would need new tires and wheels. If they are foam filIed , I am not sure you can ever get that foam off there . Even if you hack the tire off.

I agree with you on that.

I have foam filled fronts on my JD 850. About 10 years after the foam was installed, both tires started de-laminating within a few months of each other. I don't know if the foam contributed to that or not, as the tires were about 25 years old and pretty worn and weather checked before I had the foam installed, so it was about time for replacements anyway. I took them back to the place that had installed the foam, and had new front tires installed and foamed again. They didn't mention having any problems removing the old tires or the foam, and installing the new tires on the same rims. That's been about five years ago and no problems so far.

Another vote for fire here. I think I would try my luck at burning them off. Plan on re-painting them after. You'll be taking a chance on warping the rim from the heat. But that's a chance you'll have to take if you choose to burn.

I cut one tire off one time with a sawsall.

Cut a pie wedge out of one to see what you have. Regular tire dismount might work IF they are not foamed to the wheel.

It would surprise you how easy a nylon cord tire cuts with a razor blade. A roofers razor blade is even better. I cut them up all the time for different projects nuttin to it.

Google it on youtube. A sawsall will fight you BTDT...

Sawzall.BTW almost any five bolt mower rim will fit,you just need an offset that clears everything.

Jerrycpp · Dec 1, 2021

Thank you for the reply. I'm sure it had regular pneumatic tires when it was new, but someone put foam in these. They are extremely heavy, and nearly bald. It's a PM-400 Model 98014, Serial 637858, Yanmar 3TNA72E-NC 22 HP. The parts list for this machine shows 23x8.50x12 for the 22 HP, and 23x10.5x12 for the 30 HP. It also shows both using the same wheel. I just got this machine, so plead Not Guilty on putting foam in the tires. The wheel's center hole is 3 1/8, the offset is 3, and it has 5 - 7/16 bolts on 4 1/4 center - everything I've found is different in one or more of these measurements. I've cut foam tires off smaller wheels in the past, and it's not fun, so I was hoping someone had a better solution.

Jerrycpp · Dec 1, 2021

Thank you for the reply, but I'm in the middle of Washington State - too darned for away to check them out.

I've not taken any off before.I was at a tire shop one time when they were in the process of changing some and it was a mess pieces all over the floor and were cutting them off. They were going to put new tires back on the old wheels/rims. I think they were for a trash truck or land fill company.

GCR commercial tire always has a bunch of old worn out foam filled half tires sitting by the back door. They just cut on the opposite sides and they drop off. Don't even think of burning unless you are out of sight of anyone seeing the smoke. The Fire Dept. gets big $$$ for putting it out for you!!.

Check wheel bolt circle again.
Mine is 5 on 4.5 inch bolt circle.
Same as Cub Cadet, JD, almost all five bolt garden/lawn tractors and various mowers today.
As well as trailer rims, many cars, jeeps, ford rangers, etc.

I am currently running a CC rim on one side of my PM400.
Which puts the valve stem to the outside instead of on the pain to reach hub side.

I had a C Farmall that went thru a fire and the rims were REAL soft and bent REAL easy. I'd vote for the sawz-all. gm

That doesn't appear to be FWD so size isn't critical. Any wheel with the same bolt pattern should work.

cut grooves in the tires for traction semi trailler tires are often regroved to meet state inspection

(quoted from post at 16:50:22 12/02/21) cut grooves in the tires for traction semi trailler tires are often regroved to meet state inspection

Truck tires that are regroovable are manufactured with extra thickness of the tread layer and are lettered on the sidewall as "regroovable".
