I need to source some 8"x20" rims for the front of a 1985 L4150DT. The ones current installed are 8x15 and have a ribbed tire on them.

I've contacted Wold in Iowa. They have a mass produced 8x20 that has 5 3/4" backspacing for $112/ea....but I'm not sure if that is the correct backspacing for the tractor. They can build a custom wheel for $285 each to my specs....but I don't know what the spec are....but once I get the front axle back together, I'm sure I could figure it out. But...that might be some time.

Thanks!

In case anybody finds this in the search. I received this info from Kubota.

<<The front/rear gear ratio for the L4150DT is 1.497 for the standard drive train. If the drive train has the optional 17 tooth gear, the front/rear gear ratio is 1.585. He will want to select a tire size that will provide a 1% to 5% positive slippage, See attached work sheet to calculate a 1% to 5% positive slippage

The previous owner installed them. When I picked it up to work on, I was :eek: The rears were 21.5L x 16.1 Firestone turfs.

It was a bad combo....I'll get it straightened out. I scored a used pair 13.6x28 R1's mounted, with the centers from Tucker Tire. Now on the prowl for a suitable front....and I need to buy some rims. :mad:

I do believe that is the front drive gear, I also think it was just an odd way of saying if it has 4wd it has a 17 tooth gear, as there is no other options for gearing.

Now considering that you have the 13.6-28 rears you need 8.3-20 for the front.

8.3-20...yep. But first I want to measure the RC of the 13.6-28. But yes, I need something about 105 RC for the front.

Thanks!

Great info. Thx. My current set on the L4150DT is goodyear industrial sure grip 16.8-28 rear and 10.5-20 front. They appear to be the original tires. According the the calculations the slippage is greater than 5% with no drive issues that i am aware of. I cant seem to find a new tire set to get below 5%. The closest i can get is frontRC 113" and rear 156". Will this set up cause any issues?
