I was at a dealer the other day and saw a M series tractor that had wide ag tires on it. Has anyone tried to find rims and these wider tires to put on the front of their grand L?

it's tempting to upsize the ft tires on a rig to increase traction for FEL work, ect., and I've been there myself but it's all about the ft/rear tire size ratio in 4wd. anything out of the factory spects (I'm told) can change the ratio and put a bind on the power train. But you might do your math and figure these ratios and do something yourself (probably at great expense)....but the warranty would be void. why do it in the 1st place? bb

Well i spend 90% of my time in the woods and a large amount of that i am moving heavy stuff. I must have ag's but am looking for a little bigger foot print. As far as the ratios this must be my hang up since i can not get it though my head how two inches or 4 inches wider would affect it if the height or rolling diameter of the tire is the same. I think finding a rim with the correct offset and paying attetion to your clearances would be the biggest part.

it may well be that simply wider would not affect the 4wd train, but my advice is to really check it out at a more expertise level than this forum (or at least from me) I assume you're wanting more traction on both sets of wheels (?)...if that's the case, wouldn't it increase the load throughout the drive train? my feeling is that they set each model up with the particular specs for a reason. again, is it more traction you want or weight load capacity? bb

If he wants the best traction he's better off with the tires he has.
*There is no good reason.

Traction or lack there of also plays a part.

Usually wider will translate to a larger rolling circumference and will cause your fronts to try to pull the backs. A little of this is good - - great steering!, but too much [above 5%] could end up breaking your front drive when the tractor if heavily laden on both front and back. Somethings gotta slip to allow the mismatch.

precisely why on the higher end M series (7040 on up) the front end has the limited slip feature. why pretend to make a large draft animal out of a smaller (yet efficient) work horse? bb

Whoa! Limited slip it how the front diff controls slip between the front tires - - not between front and rear.

wincher,
If you can find wider tires that are the same circumfrence, you would be able to make this work. The problem is that as tires get wider the aspect ratio tends to increase, along with the circumfrence. Take a tape measure and stretch it around your front tire. Then measure the circumfrence of the tire you hope to use. If the two measurements are within an inch or two, you should be OK.
