Tire size question

[danerr]

Hi, I am new here and I hope you don't mind me asking your opinion, first I have a b7100 I have had many years, I just bought a new b2320 with mowing deck and loader, so my question is I ordered it with industrial tires, which I did receive only the fronts are 23x8.50-14 nhs and on the back they are 12.4x16 these are very large tires on the back, I stopped today at the Kubota dealer, they were closed and looking around this set of tires would be from a b26 loader backhoe, do you see any problems running these large tires, or should I have them put on the stock 6-12 front 9.5-16 rear I would like to know what you all think, could there any problems running these ? also they do look cool.
Thanks Alot danerr

Even though that's not a stock size tire set-up it's probably in the right ratio, so there won't be a problem with the 4wd.
Stock factor call out for tires is:
Front 23x8.50-12, Rear 12-16.5
Both your fronts and rears are taller by a little bit.
So no you won't do any damage to the tractor running that size.

A quick check on tire size ratio:
Put the tractor on firm ground, 2WD. Mark the rear tires where they touch the ground. Move ahead one rotation of the rear tires, and mark the front tires where they touch the ground. Back up to the starting point. Put it in 4WD. Move ahead again one revolution of the rear tires. This time the front tires should have turned more, by 10 - 30 deg. Normally the front tires are "pulling" the rear tires by 2-5%.
It is easier to do if you have two people - you want the rear tire rotation to be precise, and it is better to have someone off to the side telling you when you're there...

Haven't done the reseach but I'm fairly certain they're correct, and if not that's how it came from the factory so it's Kubota's problem if it ends up being wrong and you bind up and break something.

I've got those sizes on my B3030 and they work great and have no issues tearing up the yard while mowing either.
