tire size

[mm-r47]

What is the most common tire size in div 3 3250b class? Will a mm-r compete well.

see alot of 14.9's and 15.5's...if you have a strong motor and can get enough weight to balance it right i would say yes

15.5x38 But Genes Farmall 230 runs a 16.9x38

How strong of motor does one need? How many horsepower?

 

[DiamondPuller]

3250-3750? I would say 70hp or more to run 3.5

Not....there is a 3250 C out there, past points champ that is about 50- maybe 55 hp. Now there are some 70 + hp tractors out there running 3250, but I dont think all tha power is needed.

for 3250 3.5mph, a good running 3.75 bore 206 with a berry cam should cut it ok...I think an R would be good, but the trick is lightening it up enough to hold the nose down..

I run 13.9 36 rears that are wore down pretty good and they work well. I had 14.9 38 but they were to fast for the slow classes on my R
