rear tire set narrow or wide?

henryrit · Dec 17, 2013

my question is do you guys prefer to run your rear tire set in or out? Everyone where I pull has there rear tires set out wide except for one guy has his dished in and narrowed up and he is the tractor to beat. These are all farmall m's

If you pull with the wheels set out, it puts more strain on the axels and gearing.

I set mine in, I'm not the guy to beat but top 3 usually

I would be curious how it would affect either the axle or gearing. They will have the same load either way. It is remotely possible that one could twist off an axle but it is highly unlikely.

Wide set if one wheel slips a little tractor tends to turn a little. hard to turn back without loss. RENE'

Well it depends on what everyone else has. A little known secret to most pullers is finding the grooves left behind everyone elses pulls. That means if your in those grooves more tire is biting for you and less of the skid is contacting the track fo the sled. If most of your club is in go in to match the width of the groove. The power theories and axle snapping woes are minimal and unlikely at best. True the kinetic energy stored in your axle with the wheels our wide can cause fractures (if you have 300-400hp and standard instead of shaved tires), and it does take more torque to spin 38in rubber down a 8 ft long shaft as compared to 2ft. However, you talking a matter of 6inches.

The wider the tires are set apart the more leverage one tire has over the other, so the closer they are the straighter the tractor should pull.

My 16.9X38 tires are set as narrow as I can get them and usually beat most 18.4X38 in 4&5mph classes. The tractor rarely spins one wheel and if it starts to, it adjusts quickly. Narrow is also more effective when shifting your body weight around to compensate for an inconsistent track. When most tractors are veering off in one direction, mine usually does much less, if at all. I would theorize that tires moved farther out, should one grab more, would have more leverage to swing the nose over. This has been my experience, but doesn't necessarily match what others are saying here.

the closer the better in my opinion

The only advantage the wide setting would give you is if you are wider than the pan on the sled. Then the pan don't drag the dirt the tires dig up. Thats how I run mine and about 10 inches of each of my tires are on the outside of the pan.
