Tractor Sizing B7510 Turf Tire Size

[WayneW]

Hello. I have been reading on this site for a while now. Been looking at many tractors trying to properly "size" my new toy for my needs. The local dealer had many BXs in stock but no B series at the moment. Anyway. I was wondering if anyone knew the tire size for turfs on this tractor. All the Kubota web site specifies is the Ag tires. I know that the BXs (18/22)are 26 X12 rears and 18 X 8.50 fronts. Thanks to all for much help. This group has been invaluable.

The B7510HSD turf tires are:
front 23 X 8.5 - 12
rear 31 X 12.50 - 15
Hope this helps. Lewis

Went to the dealer this weekend. Apparently, the Turfs on the B7510 & B7610 are the same size. 33" in the rear and 23" inch in the front. The Bar Turfs are also the same for both of them at 31" for the rear and 21" front. The R1's however are different sizes for the B7510 & B7610. (Larger on the B7610) Is this why (in Kubota's specs) the B7610 has a slightly higher top speed than the B7510? (with R1's on I guess)

I think I may go with the Bar Turfs. I've heard good things about them here. Besides, with the same gear ratio, I'd imagine the slightly smaller tire diameter (31" opposed to 33") would equate into more HP & torque transfered to the ground, Yes? Or no?

I know you didn't ask about the R-4 tires but mine are:
Front 23x*.50
Rear 12-16.5
It seems to me they are the same Dia. as Turf tires although different rims.

Sorry. You're right. I didn't mention the R1 or R4's. I'm not certain of the diameter measurements of those tires. Not sure how to convert a 9.5 - 16 to a size in actual inches.

I am sorta interested in how the tire diameter will effect the actualy HP (usable) of the tractor. That's pretty much the reason for the whole "how tall is that tire" thing.
