Pulling tires for F806

I have a pretty good running but bone stock 806D that I pull. My dad has a set of 20.8x38" Firestone SAT that he took off of his 5288 and I was wondering if I have enough power to use them for pulling or if I should go with 18.4x38" I currently have new 18.4x34" and the bars are bending towards the end of my pulls
 
I would think that would be something u should tell us.
We are not watching u pull and what the tires are doing.
Going wider is not necessarily the right thing unless u
weight it up more to compensate for the less psi to the
ground. And thats the thing with new tires. They are soft
and roll the lug. Gotta know your weight and class. Then
go from there.

I should also add the question. If I don't I have enough power for that size of tire at stock hp would I if I turned it up to about 110 hp?
 
Power means nothing unless unless u get it to the
ground. Are u spinning out now ?most times I have to
throttle back so I dont spin out with the 660. All stock. At
12,000 lbs

Yes I'm spinning out. I think the bars are flexing 50+ feet from the end of the pull which is stealing power also. I've run more pressure which seams to help but not good enough to compete every pull. One of the pulls was on a new track that wasn't as hard as the others and I did well there. Beat a 4320 and 856 but most tracks are rock hard by the time the heavier classes pull. They are deep tread Michelin Agribibs
 
Most want taller tires, which is what you
will get. But I'm not convinced that's
right. When I pulled my 930 which ran a
string 150 hp as I had it, I had 18.4/38s
on it. But that limited me to 1st or 2nd
gear. I always thought a set of 18.4/34s
would have allowed 3rd or 4th gear and a
bit more ground speed. Most important at
your hp is to keep the front on the
ground. I see so many try to weight like
the big hp pros do, but 100 hp does not
take the same weight and balance as 1000hp
does. If your feont I up you are losing
lift on the skid and weight on the drive
tires. 100lbs at the front of the tractor
to keep the front down will add up to
1000lbs or more on the drives. And you
will lose those 1000s if the front is up.
The consistent winners in the low hp
classes will have the front on the ground.

Yes gearing would be a concern. I run 3L and pull TA now and with 20.8 38s I think I'd have to go down to second. Going up to 38s would help with draw bar height. I don't have an issue with the front end coming up. I put 1000 pounds on the back axles at 10500 and another 1000 in the middle at 11500
 
Old tired 806D and in the field I can spin 38's when pulling heavy tillage or in softer ground in 4th low so if that helps I can't say. So much is different than on a pulling course.
 

The track surface makes a difference too. A hard sticky track will hold the extra width of those lugs on the 20.8s. On a soft track the lower PSI onto the track surface due to the larger tire contact area will allow the lugs to slip more readily.

I just got back from the local tire shop. He has a set of used 18.4x34 Firestone SAT2s and a set of used Galaxy radials same size. The SAT2s have about 3/4" of tread and the Galaxy's have 1" of tread. Which of them would be better for pulling?

Again it depends on the track. For a hard sticky track you would want the 3/4 tread but for a soft track you would want all of the one inch. Most guys seem to do OK with those Galaxies but I had a set once that split in front of the lugs. If I were pulling that 806 I would be turning it up to the max, then get her down to under 7000 and pull in 6H. Have some FUN!! but that's me.
