My BX 23s tires seem fine for what i do. Was thinking about smaller tires for the B2601. Would keep the tractor from caking up mud in the fender wells, I would hope (see my gripe post), and lower the center of gravity.

Has anyone ordered them with smaller tires? is that an option? I know, I could call the dealer, but thought I would hop on here since I have not been on here for a while.

You would have to get new tires that have the same relative diameter front to back as the old tires. That is so the front and rear tires will cover the same distance as you travel in 4wd. If you don't do that it will put extra wear on the drivetrain.

Sorry if I'm not explaining this very well but matching the tires is important.

Grandad4 nailed it !

There is a built in ratio between the rears and the fronts ....... the fronts spin faster than the rears, but at what ratio?

You could place a string around the centerline of the rear ......... measure that string, then do the same with the fronts........... divide one into the other, that will give you the ratio of the 4wd drive line.

ANYTHING you place on that tractor will need that ratio - or YOU will ruin the internal driveline, no doubt about this, other than you stay in something very very soft.

Add ballast and weights to lower the COG ..........

I understand that. I was looking into putting the BX23 tire size on. Actually, something 2" taller than BX23's would be perrrrrrrrrfect, but, eyeing the BX23 size real hard since it is a standard size and i have them on my tractor now and work just fine.

I don't know about bx sized tires, but different models of the B use smaller tires, the smallest is the b2401 and it uses 5-12s in the front and 8-16s in the rear, and it's the same chassis, so you could try something like that.

If you've got those gear ratios and tire diameters all figured out, I hope you'll post a picture of what you ended up with. A low-rider B2601 should be pretty cool!

Have to say though putting on smaller tires for the mud is just backwards of what those mud-bog 4x4 racers do. They aim for the absolute tallest, most flotation tires they can find. When they get stuck, it's usually from getting high-centered in a mudhole. Yhen they clean it off and try again. Probably a lesson in there somewhere.

A list I got from somewhere ( I don't remember where) shows the gear ratio on the B2601 as being 1.47. Front tire turns faster than the rear tire.

Unfortunately I don't have anything on the BX series...perhaps someone else may?

This is a start anyway...

You could probably get a close approximation by measuring the BX front and rear tire diameters, and dividing the rear diameter by the front diameter. My guess is you could get pretty accurate diameters, if parked on a flat concrete surface, using a level set on the tires, and measuring down to the concrete from the bottom of the level, assuming the level is set parallel to the concrete surface.

The string method mentioned above works equally well. Best to have the tire sitting on the ground on top of the string when you do it, because the effective tire diameter will change with air pressure and load felt by the tire.

Choosing smaller tires will definitely hurt your effort to optimize performance in mud.

It will also reduce ground clearance and make for a rougher ride.
