I have 5.50X16's on my M now - both flat so I'm getting new rubber on this week. Are there any pro's or con's for each of the three sizes I can put back on it? That would be 5.50, 6.00 or 6.50 sizes in a 6ply tri-rib. Is one size easier to steer without power steering or is it just a matter of personal preference? I'm leaning toward the 6.00X16's but I don't know how the size affects the diameter. I want to get a pair of 14.9 or 15.5's for the rear this spring if I can find some good mounted ones at an auction so I want the tractor to sit right. Thanks for any insights you might have! ...Randy

I either have 6.00x16 or 6.50x16 on my 504 and it has a little negative rake with 14.6x38 rears (i think). I always thought it was the funky front end I have causing the negative rake. Wider is better for floatation, and NEVER use worn out truck tires. They do not steer well, they just slide. Stay with tri-ribs.

You didn't say whether you have wide or narrow front end.
I don't think a 6.50 will fit under the bolster of a M. I have several SMTAs. One has 6.00s and the clearance of the three rib is less than an inch. You could, of course, add a spacer to the top of the lower bolster. I don't really like the look. Maybe the front tires come with low profile variants. I dunno.
BTW, I think you will find that the 15.5 x 38 have nearly the same diameter as the stock tire. I believe the 14.9 is larger than either of the other two. Goto the Firestone Ag site to get the diameter data.

Randy: I don't think you'll see a huge diameter difference between 6:00 and 6:50. I always ran 6:50 on my 300 with 13.6x38 rears, tractor looked alright. I've had them on with narrow front so they will fit.
On my 560 and 656, nothing less than 7:50.

Hi. I have a narrow front.
I never gave the clearance any thought because the parts book indicates both 6.00 and 6.50 will fit. I wanted a smaller tire for ease of steering but I might reconsider the 6.50 size after all for the flotation.
I'm going to use this tractor for plow day events and hay plus other odd jobs around the place that the bigger tractor isn't needed.
You said you don't like the look? Of the spacer or the bigger tires?
Thanks for the reply! ...Randy

Hi Charles . I'm by far NOT an expert on front ends so I might be totally wrong here but if you have negative rake I believe you might have a problem. The spindles vertical axis should point in front of the wheels true vertical axis at the contact patch by a small amount to get the self centering action out of a turn. To much and it's hard to turn , to little and it's hard to keep straight.
That looks like a brand new loader. NICE!

The "look" is a totally subjective thing. You may prefer it. I don't care for the big front tire look on a two wheel drive NF tractor.
I have always found that flotation is always adequate when the trike front tires are set close together. They act like one big wide tire. They penetrate less than the rear tires in muddy situations.

Randy: I always set my 300 narrow front wheels, dish in with lugs on outside of cast. 6:50 tires will still be 2" apart at bottom. They steer well that way.
