New7040 tire option

[94BULLITT]

I seen where I forgot to get the measurements for yall,will work on it today and get the side by side photos....

I found the specs

Goods specs, if I counted correctly that's 2.2" taller, I'm not sure if it would make a ratio difference but that's not a huge difference in sizes

The circumference is not much different. I found a place before that had the revolutions per mile but I can't. It was not much different either.

2.2" taller is quite a lot of inches in circumference. 8" to be exact. Static radius is what is important for gearing calculation though. The radius as measured from the center of the axle to the ground, specifically, due to squat. I'm wondering if you couldn't lower the air pressure to get the same radius measurement where it counts. Those tires show a static radius difference of 0.9". That much will definitely put the driveline in a bind unless the air pressure is adjusted down significantly or a half inch or so is ground from the bar height.

The front axle is already geared to pull more than the rear when in FWD, adding circumference will only ask the front axle to pull even more while engaged.

I would just like to have a wider front tire for better loader working ability and that way it shouldn't change the gear ratio

I'm with you on that one. The problem is that any of the wider tires that we've found are also taller. Tall enough to cause backlash and strain in the driveline. Thus the conundrum.

I dunno I ran mine 8hrs pulling 15ft batwing and several hours doing loader work,I just haven't seen/felt/heard anything. I don't run very much 15lbs front,10lbs back...

I wish I had a number to call Kubota directly and ask someone on their end and see what ranges of ratios are safe

 

[PoorPlowboy]

Was the front axle engaged doing those tasks?

Nauxier, my local dealer didn't want to sell me the wheels and tires because he said Kubota's position on it was "not recommended due to driveline stress." I want to hear it direct from Kubota though.
