B7200 Replacement Tires

[Tadams72]

Just picked up a B7200HST-D from my Dad. In typical Kubota fashion, they are nearly indestructible. This one is in bad need of tires however. It has the turf wheels (20.5x8-10 fronts and 275/65R15 car tires in the rear). I am trying to keep replacement costs down so I am considering the following tires. Carlisle Trac Chief 20x8-10 fronts and 27x12.50-15 rears. Doing the math I “THINK” these will work without binding assuming the ratio is 1.464 on the transmission they should be near perfect.

Tractor will be used for blade work, box scraper, occasional snow removal, field mowing and occasional yard mowing.

Looking for an expert to weigh in here before I purchase. Price is about $400 total. Thanks.

You got the fronts right, but way too small on the rears.
You want 31x13.5-15.

Yeah the manual shows 31’s or 29’s with the 20.5 front. Doing the math and assuming the 1.464 ratio (which is what my research shows as the B7200HSTD ratio) these should be almost perfect.

Carlisle shows the following rolling circumference:

20x8-10 = 57.1”
27x12.50-15 = 83.1”

57.1” x 1.464 (ratio) = 83.59”
83.59”/83.1” = 1.005 or 1/2% of perfect

The only thing that bothers me is if I got the ratio wrong some how.

Am I missing something? Damned if I know but seems like I got it right. [emoji2373]

Yep deeper look they did offer both sizes.

So you should be fine running them.
