IMO BFG's are not a great tire, but a good tire on all tracks, but STS's are only great on a great hp track, otherwise, they suck. STS's are only good on an ideal track.
Absolutely not true. I had a massive hook with STSes on a horse track this year, and had several other great hooks on varying tracks. However you must know the right pressures for the surface and the gear combo you want to run. STSes at high pressures will spin out....been there, done it.
The STS is the best pulling tire all-around. The only thing they suck on is greasy/muddy tracks.
Go to any of the midwest pulls and they're about all you see on dedicated trucks. The guy from Ohio that won our unlimited-single class ran 6 of 'em on his dually CTD. Pops gave me a really hard time once when I said "winners run STSes" and then it wasn't too long after that, guess who had a set
The BFG is OK but they tend to need to be spun hard once they lose their edges. Tomac and Burkhart ran them for a long time. Burkhart was sporting STSes the last time JB saw him.
I have never seen the Pro-comps work at all.
And the thing is, if you truly have 700 rwhp, you're going to need 33" or 35" STS (3rd or 4th low range depending on pressure) or the 35" BFG and go 4th gear and spin the tar out of 'em.
If you want to be near the front, don't street drive your pulling tires....because most of the competition is running sharp tires!
One last thing, just from experience. At 500rwhp, many sharp tires will work fine; it's more of an idiot-proof situation. It's at 600 and above where things get decidedly more tricky and you've got to have a really biting tire that's properly inflated for the surface and the gearing you're trying to run.
