to those looking for 20.5x8-10 tires

[nostep]

I know this thread is old, but ...

Bikerdib, Did you take them off because you are nervous, or because they didn't work?

Didn't anyone think to make the back tires a touch smaller if you have to. If you you go down to a 20" tire (from a 20.5" lets say), then you can simply go down to a 28" tire instead of a 29".

I'm running out of tread (and rubber) on my AGs for my B6100. I really want to try Turfs. Manual says 20.5x8-10 on front and 27x8.5-15 on rear. I need rubber and rims. I guess I'll keep digging for a solution.

Well guys, nearly a year ago the front tire choices in this thread had been narrowed down to either a Carlisle All Trail 22x9.50-10 or a Carlisle AT Chevron 21x11-10.

Where you able to get either mounted on 6" rims and were there any clearance issues when installed?

Has anyone measured the RC of each and which one was best suited for use on a 4WD?

Thanks

I took them off because they still didn't give me the traction I wanted/needed. My dealer had a set of R1s and rims in old inventory and we found some R1s with the rims through Kubota wholesale for the rear. The dealer gave me a great package price since he had the fronts in inventory and wanted to get rid of them. I was much happier with the R1s.

I no longer own the tractor though, sold it and got a B3300SU with FEL.

I just mounted a pair of the Carlisle All Trail II in 22x9.5-10 on my Kubota B1750 4x4 to replace the Bridgestone 20.5x8.0-10 turf style tires which had little tread left and were getting side wall cracks. The B7100 and others also use the 20x5x8-10s. I spent a lot of time looking and following the various threads here before deciding. I felt that the All Trail 20x10.0-10s would be too small, since other posts have pointed out that it is better to run a 4x4 in a lead condition (front tires slightly larger than stock) rather than a lag condition (front tires slightly smaller than stock).

I'm very happy with the results. There are no issues with sidewall clearance on my B1750 (although there may be on other tractors -- you just need to do a visual). The 22x9.5-10s are slightly taller (0.5-1"), but no wider than the 20.5x8-10s they replaced when inflated to their maximum 14 psi recommended pressure. They have a rounded shoulder profile rather than the square profile of the Bridgestones, and of course a much more aggressive tread, which is what I wanted for the 4x4. My rear tires are 31x15.5-15 z-bar style (not turf, not ag, not R4s, don't know what else to call them) with a tread pattern similar to the All Trail II's.

Note that the 22x9.50-10s have a maximum load of 585 lbs each, so you probably should NOT use these with a front end loader. My B1750 is fitted with a front hydraulic plow blade, so this load range will work just fine. I think you could put a snowblower or broom on the front too, just not an FEL.

I want to point out that the rolling circumference, NOT the loaded diameter, is the most important factor when trying to match the front/rear tires on a 4x4. Over- or under-inflating to change the apparent diameter does not make a difference. Think about the limiting case of a bulldozer tread: every inch of it has to contact the ground to complete one rotation, and it does not matter whether that bulldozer tread is elliptical as it normally is, or round like a tire. You can reduce the tire pressure until it looks flat, but every inch of it still has to contact the ground to complete a rotation, right? All you do with the inflation pressure is change the size of the footprint.

My 2 cents and a little more!

I love the looks of this tire and want an aggressive tread like this. Like you, I have been looking and your post is the way I was leaning. My Firestone's 21x8.00-10's are just about shot. Out of curiosity have you checked the RC of these tires? Would make the decision easier before pulling the trigger.
Thanks for any input you can give me!
