JD 272 mower tire mounting

[Gerben]

Hi everyone
I got an older john deere 272 mower
The guide wheels/tires are worn tk the point that the one tire split and fell off
Can only get new tires through John Deere dealer complete with wheel for about $1000 each
So i found 4x12 smooth solid tires online that are meant for mowers etc. (Same size as what's on there now)

Here's the issue though
the inner dia. of the tires is 8-1/8"
The rim inner dia. is 8-5/8

how in the world do i get these tires on there?

Have you tried. Clean and smooth the tire surfaces of the rim sections. Real tire rubber lube on the inner diameter of the tire and on the rim where the tire rides. Get some longer bolts (or all thread rod) and use the bolts to pull the two pieces of the rim together, stretching the tire as the rim pulls in. If you use bolts you may need to swap to shorter ones before the rim sections come together. Warm tires will stretch easier.

No i haven't tried that yet, but 1/2" difference seems a bit much to stretch, or is that normal for split rims to be that tight? Seeing the old tires can be taken off without any effort, i realize they're old and dried, but would've assumed that they were tight on the rims

Who quoted that price?? JD Parts online shows tire # M83578 for $68.38.
It also shows a tire and wheel assembly #LVA 15397 for $ 221.68

How much did you pay for an incorrect tire that doesn't fit?

 

[Jim.ME]

They are likely assembled setting in a jig to align the bolt hole with a press pushing the rim halves together.

Another option is you can return them and try to find some with a larger center.

I am seeing the same pricing as Scott 730. It does appear the original bare tire is not available/back ordered, and they are subbing the new complete tire and rim.

The original tire is not available
I searched the internet hi and low to even find the ones i got(that sadly don't fit)
I'm just past the 30 day mark to return them
Paid $80 CAD total incl shipping

I was wrong on the $1000, i just double checked the quote i got last year from local john deere dealer, it's $759 cad for 2 of the wheel/tire assemblies
Kinda crazy though, considering i bought the mower for only $40 at an auction.

I put tires like that together for my cultivator. They are supposed to be a stretch fit. I cleaned the rims well and used soap for lubrication, but I think tire grease would be better. My shop press pushed them right together.

If you are past the point of returning them it does not seem you have anything to lose by cleaning the rims, lubing the tire and rim, and try pressing or pulling the rims into the tire.

You now posting that you are in Canada helps explain the range of prices you quoted and why we are seeing lower prices. Adding your province in Canada to your profile so it shows in your avatar when you post, would give us a clue that you are looking at a different monetary system than most here.

Throw the tire into a pot of boiling water. 50/50 chance that will allow it to stretch enough to mount on your rims.

Before I got too aggressive pulling that rim together I'd probably call whoever sold the solid tires and ask what bead or rim diameter they're actually designed for. Half an inch on diameter doesn't sound huge until you think about how much rubber has to stretch all the way around the circumference. If they confirm that's the intended fit then the warm tire, proper tire lube and long threaded rods make sense. I'd just want to know for sure I'm stretching the right tire before finding out the hard way that the nominal 4x12 size isn't quite the same standard as the Deere wheel.

They look like jd planter tires and rims, but I’m guessing bigger.

Sounds like you own them, so might as well try. They do normally press together very hard, not sure what the normal difference should be.

Boil the rubber, and have a good shop press or 3 long enough threaded rods ready to clamp it together.
