ATs out back, MT's in front?

I was runnin the bais ply's
I would run 30psi in the front and 65psi in the back. it could just be are wonderfull Michigan tracks also.they tend to have little clay in them and are a touch soft.

a touch soft? I have heard of guys from michigan being upset saying their truck was stuck in the sandpile, I was like why are you upset. I didn't realize they meant the sandpile was the track!

Way too much in the rear, from my experience. I had 'em like that once, and that was the last time, spun out like mad.

45 in the rear is a good starting spot.
 
On the BFG's 38 rear and 16 front seem to work great. But like I said that is BFG in a load range D tire. I would think that the load range of the tire would make a difference.

Rod was running STS bias ply's. We found that the STS bias ply did not work as well as the Radial STS's. That might of been the problem. Also Ingram was running STS's in the front and ATS in the rear at the last pull.

I agree with bubba the AT's on the back so they don't dig down as much and they don't throw a big pile of dirt in front of the sled. Also the back you have a lot more pressure pulling down on it from the sled so the more contact surface you can get with the ground the better.

Isn't that why the tractor cut the tire?

to get the most contact to the ground and to maximize the footprint of the tire the idea is to lower the lug and contour it to the circumference of the tire but keep just enough lug so the weight that is applyed to the tire through the footprint will pack the ground as well as hold on to keep forward motion of the tractor and not dig to much dirt to be drug by the sled
it would be a great advantage to be allowed to cut tires for truck pulling you could have a set of used tires cut for pulling and not have to spend a lot of money for new ones but what is a street class without street tires:rules::bang

they do its called featherd , easy to do and works
 
Great info on tire setups here! I to am looking into the STS's only for me it will be in the front. I need more tire up front...currently running 255/85r16's BFG MT's on the 6.5" dually rim. I am planning on going to a 10" or 12" wide single wheel up front, lose the dually spacer and run either the 33x12.5R16 Radials or the 33x13.5R16 Bias Ply's....can't make up my mind. Any imput on the Radials or Bias ply's?

As for the rears, I will be running the 255 BFG Mt's and in the past on the really hard tracks (unfortuantly our tracks suck and I only pulled on two good clay tracks this year) and there I air'd them up to almost 80psi...worked great and gave a good tread patern. Also I found I was able to keep the wheel speed up higher. On our loose tracks I would drop down to 55-60psi and still blow out the tires (this year I will try dropping down to 50psi) but I think the reason for the major blow out was due to the fronts not getting enough traction...hence wanting to go to a wider tire up front.
