Switching L39 TLB turf tires to R4 or possibly AG tires

[ashwood486]

Hello all, I recently purchased a L39 TLB with good turf tires on it. I am not happy with them around my barn in the mud and manure so, I want to replace them with the standard or a more aggressive mud type R4 or AG tire.
All my research seems tells me that a complete rim change out on the rear is the only thing possible but, the front rims stay the same and just a tire change is needed. If I am wrong or there is a better way to go , please help me with any advice from someone more knowledgeable than me.
I have been searching for some type of rim cross reference on Kubota tractors but, to my knowledge nothing exists. Is there other tractors that will interchange with the L39 bolt pattern.
Thanks

Yes turf tires on the rear will have a different rim...
lots of rim/tire combinations ... all you have to do is Keep the front:rear ratio the same.

Is there a list of rims that fit an L39, I found some rims and tires on eBay that seem to be a great deal but, just not the same size.

I really felt the need to change my tires to industrials, I'd upsize slightly like Kubota should have in the first place
43 x 16 x 20 rear vs 40 x 15 x 19

29 x 10 x 16.5 front vs 27 x 10.5 x 15

Ratio stays the same

Thank you, that's a great idea, I have been worried about the ratio,
I will definitely start searching.

Ashwood486,

Here's a link to the Wholegoods Price List. On page 5-12 there is tire info for the L39. Hopefully you'll find some value in this info.

Below is a snapshot of the tire detail in the event the link doesn't work.

To get them from the dealer if you multiply two times the 231. you have the price of new rims with industrial tires less freight.

Thank you, , I'm still trying to figure out the bolt pattern on the L39, because when I see the larger tires, it's mostly with a John Deere,
