new tires versus worn out

Pulling farmstock 9500 and 12500 ,10mph with 18.4 x 38 . Currently have radial with 90 percent tread . Why are some telling me to go buy worn out 30 percent tires . Whats the advantage of this versus my newer ones . Will I actually gain a lot or will it not be worth it ? Pros and Cons ?
 
New tires with tall bars will dig down and pile dirt in front of the sled. Less bar and your not digging so deep. Once you dig down you also loose hitch height.
 
OK that makes sense but wont I be sacrificing traction grip ? Seems like a trade off ? lots of tread lots of traction but more dirt pileup versus no tread no traction no dirt pileup ?
 
Lots of tread doesn't mean lots of traction. Go to a pull and see what everyone is running for bar height. We generally prefer around 1/2 to 5/8's of bar. Of course each track is a little
different also so what works good on one might not work on another. I have 3 different sets for my puller.

I pull a 10500 Hot Stock with uncut 20.8 Power Saver radials in a 12.5 MPH class...They are about 35% tread and hook up great to most tracks..No one runs new
tires..You want old tires that are hard and have short tread so that the bars wont roll over on a hard track.

I pull against a guy with uncut 18.4 x 38 Power Saver radials that are only 15-20%...He's tough to beat on certain tracks..

You dig down, now you got a hill to climb out of also.
 
Depends on the track. Probably not
very many tracks are going to be
beneficial to have 90 percent tread.
If they dig, it's a disadvantage.
A balder tire is not going to dig so
bad if they do slip. And in my
opinion, puts more surface area of
tire to the ground if you have just
the right amount of tire bar for the
track. Bars are your non slip
traction. So you need them. But to
much bar takes weight off of the rest
of tire that's hitting the ground. Way
to much bar, only surface area of the
bar itself is on the ground.
Think of it terms of a racing slick.
And add just enough bar to it that
tire won't slip. Then find a happy
medium for the various (not all the
same) tracks you pull on.
