JD 650 Flat Front Tire - Lug Nut Removal?

Edensgardener · Feb 15, 2015

OK, I was out planting onions yesterday when I heard a terrible sound - thankfully, it wasn't a hose as I feared. It was a tire! How odd I thought as it was just sitting on the pasture, flat land. Anyway, I am trying to change the tire as it's a pretty wide gash it looks like, and green ooze is coming out (so doubtful adding more and air will do any good.)
.
My Ford F150's lug wrench won't fit the lug nuts. Is the #7 that is on the nuts the size of the wrench I need to have?

I'm hopeful it's a tube in there that a big ol thorn just punched through, and I can run up to TSC to replace, but the green slime is coming through a slit in the outer tire.

7 is an indication of the hardness of the bolt, not the wrench size. It will be metric, but I'm not familiar with a 650 enough to tell you the size, maybe an owner will chime in...
As for the slime, you are about to get an education on the joys of using the stuff. Personally, I hate it.

The 7 is probably the metric hardness grade of the lug nut / bolt. The green slime is also probably just that. Green slime additive that was put in the tire to seal a previous leak. Very messy stuff when changing a tire or tube.
The lug nuts are probably metric (F150 lug wrench is probably in SAE standard sizes) so you'll need metric sockets. It could be 15,16,17,18,19,20,or 21. You probably have tubeless tires. It should say so on the sidewall.

Thanks, guys. You know, I don't recall ever putting the stuff in there - it may have been previous owner. But at any rate, I HAVE used it before in wagon tires, so who knows. I did remember that I had my late father's old 4 way lug wrench and I was able to remove tire - now to find out if it's got a tube inside, (hopefully), then, if it is, to track one down. I'll have to take it to a tire shop to do the fixing. I don't have the tool to get the rim off the tire.

The front lug bolt on my Yanmar built 4100 is 22mm...so yours might be the same. Seems most lug sets supply 21

Looks like this is not going to be an easy find. Why does TSC not just drop the T from their name? I don't ever seem to actually find TRACTOR supplies there...... sigh. It is a tube. 5.00x12 tire size, (firestone on there), Was hoping to get it out of the field before the rain and cold front comes later on - but that's not looking hopeful now.

Thanks again guys!

Last tire I took in to get a tube only cost 23.00. Was pleased asked the man if there was a thorn or nail in the tire. No he had checked. Put the tire back on the tractor and the tire was flat before getting back to the barn.
Wish you better luck. Might want to run your own hand in the old tire. Some places will not let you in the shop of course. with the slime and cracks in the tire you might spend your money on a new tire and forget the tube . I wish I had done that.

Well, I got a tire shop to take the tire off of the rim for me - I patched the tube - seems to be holding air just fine - but now "they boss" won't let him re-install it. WTH? So I googled and found this Changing a Tractor Tire - Mounting | GEMPLER'S
But I'm not sure what it's talking about with "beads"? It's not a rear tire - thankfully, THAT would have been HEAVY!! lol

But can someone please explain what this instructional is talking about regarding "inside bead" versus "outside bead" and/or any tips on how to get this all back together. Rain and cold and such is supposed to be heading out way and I really hate to leave my tractor out in the field.

Don't know the reason why the tire shop won't put it back together. It's pretty simple to do and it's not a split rim. Not much different than changing a car or pickup tire. For tubed tires you have to put one bead over the rim then insert the tube. Install the valve stem in the stem hole on the rim. At this point I usually put a little air in the tube to straighten out the wrinkles. While keeping the valve stem centered in the rim put the second bead on. I apply tire lube to both tire beads to help them slip onto the rim easier when inflating. Don't exceed 35 PSI when inflating to seat the beads and stand behind the tire when inflating. Once beads are seated lower PSI to factory specs.
If you have to install the tire back on I suggest either laying the rim on the floor or mount the rim back on the front hub and proceeding as above. You will need a couple tire irons to manually work the bead over the rim and be careful not to put the irons in too far as you could pinch the tube and damage it.

The inside bead is the one towards the tractor. If you check the rotation of the tire (Tread is going the correct way) and the tire is completely off of the rim, the inside bead is the one that goes on the rim first. Then the tube is inserted and a small amount of air is put in to round it up slightly. The stem of the tube is secured through the rim, so you don't have to go fishing for it later. The outside bead is put on the rim being careful not to pinch the tube. Air it up to seat the bead and re-deflate the tube. This lets the tube get any wrinkles out. Inflate to the proper pressure. Until you have done a few, it will be strenuous job. Most tire shops don't know how to do tube type tires. If they pinch the tube they have to repair or replace it, so cost vs profit they don't want to do it. From what I've seen you probably wouldn't want them to do it anyway.
