John Deere 650 tire replacement thoughts

[BCinMI650]

Hello All! my little MFWD JD650 is getting meaner and meaner as I continue to rehab it (with quite a bit of help from ya'll). It has recently been relegated to hard labor in the more untamed/swampy parts of my property as a 60" Woods Mow n Machine fell into my lap and has taken over mowing duty. Due to this, I wanted to upgrade from the turfs that are currently on it (Front Lawn/turf: 23/8.5-12 and Rear Lawn/turf : 31/15.5-15) to Ags or Industrials utilizing the same rims.

Now for the questions... if I swap to a like-sized tire (Galaxy Super Trencher on rears and Carlisles or Deestones on the front for example), do I risk damaging the MFWD system? Do you see any issues with this setup? preferences of the Ag vs the industrial?

I like the wider stance that these rims provide given I do have some hills and also do some loader work so I'd like to keep them (in lieu of buying a set of the OEM rims that came with Ags). I plow with it during the winter and have been using a box blade to level out some parts of my property. I eventually plan to add a small disk harrow to my inventory for food plots as well. Given all of this, what are everyone's thoughts?

Thanks for the insights,

BC

You ask some tough questions... I've understood that you will need to replace the rims going from turfs to either Ag or R-4's..
For matching the MFWD, would need to know the ratio of front to rear circumference and use that as a guide for new tires.. might be a tough nut to crack..
:mur:

Might be best option to move forward with your turfs.

It looks like the Galaxy Super Trenchers are the same diameter as what you currently have and would be a cool upgrade.

The Carlisles also look to be the same diameter as your current front tires.

I agree! But when you dig into the details it appears there is a small difference between what each manufacturer considers 31 and 23 so you wind up with a small variation from the OEM tire. I was kinda hoping if I went with the Carlisles for both front and year, the discrepancy would both go in the same direction and I壇 wind up with the same ratio front to back as the OE. They would be a bit more expensive then the Trenchers though (and never really on sale) so I wanted to explore all options.

They should be close enough in dirt. No different from new rears and worn fronts.

Good point

Are going to order the tires online, or from a tire shop? If from a tire shop, tell the about your need to get pretty close to the mounted diameters of your current tires. I did that when I had to buy new fronts for a little Shibaura.

I was going to order online to save some money, but that savings go out the window if I break something as a result of an uninformed decision.

Like what?

If changing the ratio between front and rear by a couple percent really does throw something off and I screw up the MFWD system. I've read a couple pieces where they say 2-3% is acceptable, anything more will cause problems, but they were also in reference to MUCH larger and powerful tractors.
