Early to mid 80s B8200 gear 99% of work done is scraping 1/4 mile driveway of sugar sand.

Got some Carlisle Turf Pro R-3 Lawn & Garden Tire - 13.6-16 LRB/4ply and wanting to get some new fronts of the correct size for the 4wd ratio, which I believe is 1.691.
The rolling circumference is 112.8.
The fronts i was thinking about is the Carlisle Multi Trac C/S Lawn Tire 25x9.00-12, 4 Ply which has a mounted diameter of 24.9.
24.9 x 3.14 = 78.186
78.186÷112.8 = 0.6931382979

This should be good to go if my research is correct, but want to have someone else verify it.

112.8/ 78.186= 1.44271, That will be OK

So I did my math backwards....I can get it closer now that I can get the math right. Thanks
I've got an '87 B8200 and the operators manual calls for 24x8.50-12 for 4wd. 23x8.50-12 for 2wd
