I trusted the manual and bought the wrong tires.

The circumference is +.02 with the new AG tires. Over time the wear will bring it down, but the rear tires will also be wearing, just at a slower rate. I am fine with the rolling circumference using the new 8-16 tires, my initial worry was that the 10-16.5(F) 17.5L-24(R) setup was not from the factory. I know now the setup is original and the rolling circumference of the new front (8-16) AG tire will work, but I don't know if a 8-16 R1 AG tire will replace a 10-16.5 R4 Industrial tire. I just don't want to try to stretch the 8x16 over a wheel that should be 16.5 according to the tire. I would think the sizes would be the same between patterns, but if they are not, I could use this tire. I guess I'll have to do some more research and find out if the different factory tire sizes all had the same size wheels. Thanks, Henry

Ok, that makes sense. The Manual calls for 8-16 front and 13.6-26 rear. I currently have 10-16.5 front and 17.5l-24 rear. You could be right about both being changed because I can't find any other examples of these sizes on a l3650. The big question is, do I have a proper front to back ratio. I have never felt any binding or trouble out of the current setup. I will more than likely buy the 10-16.5 tires for the front. If someone has a formula for calculating this ratio, please let me know. I just want to get it right. I also may have some 8-16 tires for sale soon. I can't send them back to the auction. No big deal Thanks, Henry

Regard rolling circumference. IT"S NOT A BIG DEAL. Many tractors have what's called "Front wheel assist" and the fronts run Faster than a perfect match

Tractors Usually run on soft ground, they turn right and left One wheel goes farther than the other. NO BIG DEAL.

It's OK if they tear up the ground a little.

But get tires you like the looks of, because they last a long time....

16 & 16.5 ARE NOT THE SAME. One is normally a tube type and the other tubeless. Do not try to mount the wrong bead pattern.

That's exactly what I thought and why I already listed the tires in the private party ads. Kubota's part diagram doesn't show any difference in the wheels, but the tires should dictate the rims actual size. Well, I guess I am going to buy a new set of 10-16.5 tires tonight. If anyone is interested, the 8-16 R1 AG tires are listed in the private party ad forum. From now on, I will check the tractor when ordering parts and not just the manual. Lesson learned. Thanks for all your help, Henry.

The new (8-16) tires are the AG R1 Lug pattern. The old ones are 10-16.5 R4 industrial. I think I understand. The rim is the same, but the tires are sized differently between styles.

The rims are most definitely not the same. The R-4 rims are wider and larger in diameter.

This doesnt look good. ... :confused3:

Don't feel too badly. I did the same thing last year. In my haste to buy tires for my Massey, I ordered what was listed in the specifications when my tractor was being restored. Got my beautiful tractor back from the painter only to discover I had the wrong size,and they were rears, so $500 each. I discovered that many tractor models can be equipped with various tire configurations. Luckily, I sold my new tires and did not get burned. Hope you can also!

I think it's bomb waiting to blow up in your face. Sell fast and by a real GREEN tractor!

Just kidding.

I've got a green tractor, I just can't keep it running. Not kidding!:laughing:

How much did you pay for the 10 x 16.5 R4's? I paid $165 each for 10 ply.
