tire width 13.6 or 15.5 ???

jandmoutdoors · May 24, 2015

Okay it's time to re tread the Farmall M. Currently has 15.5 - 38's on 14" rim. Personally for what I use it for I find them too wide. Can I use the 14" rim for a set of 13.6 and will it look wrong as far as ballooning etc. With my disk set and two bottom trailer plow I can not get my equipment set far enough to cover my tire width. I should rephrase that I can if I flip the rims but I dislike the look of them flipped. They are slid all the way in and are dished out now currently. Thanks for the help !!

Buy wider equipment , is my opinion , I run 14.9 x38 rears on one of mine and 13.6 on the others but they are on 12" wheels . I pull a 12' #37 international disc.

I hear what your saying, I have a M with some wide rims also, with 14.9 X 38 tires, Every time my tire dealers see that tractor, he cant believe the tire doesn't spin on the wheel, I agree there too wide, but a old blacksmith here, widened them out, and i got a hold of them. But idealy you should have some 11 in rims for the 13.6 x 38.

You wont gain more than an inch or so with the narrower tires.If you need less width,reverse the wheels.My SM wheels are set at 60" C to C. to follow a 30" cornrow. wheels reversed

Is that 14 inches inside from tire bead contacts? Lots of the 14 inch wide rims sold to fit a M type wheel had a offset center so they could be mounted more in or out by turning them around and moving to the other side to keep tread rotation correct.

D Slater To be honest I am not sure I have not taken the tire of the rim yet. It blew on sat and I haven't gotten around to taking the wheel off. I am doing it by myself so I need to muster the energy to get them off. So from what I'm gathering is the 13.6 might be to small for the 14" rim.

13.6 would go on a 14 wide, some pullers use them like that on some tracks. But for a working tractor the rim edges will hang out from the sidewall some and you won't gain hardly any on getting narrower. Unless someone bought replacement rims you probably don't have over 12 inch wide rims. Measure the rim outside to outside from where the tire beads are on the inside of the rim wall, then subtract about a 1/4 inch to get close to the rim width.

I think 13.6 is to small for an M, put some 14.9's on it, they are taller and between the other two on width.

Ive got 14.9's on mine, looks perfect in my eyes! Had I read this earlier I could have taken a few pics for proof.
