Got this from M/T website, this is the same procedure I used
http://www.mickeythompsontires.com/tech.php?bulletin=s4
ET DRAG® AND ET STREET™ TIRE SCREW MOUNTING PROCEDURE ON NEW RIMS
MOUNTING PROCEDURES FOR TUBE TYPE TIRES
1. Begin by Drilling 12 equally spaced holes on both the inner and outer flange of the rim. Drill the holes so that one hole goes straight into the rim and the next hole goes into the rim flange at a 45 degree angle (see diagram #1).
Note: (Mickey Thompson strongly suggests that you use Drag slick mounting screws only, and that you follow the rim screw manufacturers suggested drill bit size.)
2. Trial run the screws through all 24 holes. Running screws in the hole and back out again.
3. Check for any sharp edges that the screw may have pushed out or caused during the trial run through. If any sharp edges are found debur and make sure rim is smooth and clean.
4. Mount tire and tube. Have professional install the tire and tube on proper equipment or see Mickey Thompson tech bulletin #2 for help.
5. Inflate the wheel and tire assembly to 20 psi.
6. Install screws into wheel and tire assembly. Deflate assembly to operating pressure. Inspect rim flange and bead area for proper bead seating. If bead is not fully seated, reinflate and reinstall screws.
7. Static balance or "Bubble Balance" the assembly once screws are installed.
8. Periodically you should check the wheel for loose screws and inspect the rim bead area to be sure that there is no bead area separation.
Note: It would be good practice to inspect after each pass when you are checking your air pressure.

My slicks need a few passes to rotate a little but then don't seem to move again. I'm in the same boat of not wanting to drill holes.

Kind of my concern... I just put a radial on (goodyear ss) and woudl rather not bother with the screws.. the hoosiers I was running last year moved like a SOB and definately needed screws, these I'm hopign won't, but if they do then so be it.. I'm probably gonna put 8 per side and call it a day, there's plenty of people running less then that going way faster then I ever will so it's probably enough/overkill as it is.

If you have the proper screws in the proper location they will not leak...But yes, the added benfit of the silicone is that it could help guard against leaks.

Along the lines of the post above. I always throw away dull screws. Buy an extra pack & a sharp screw will not push bead away. It cuts in and bites like they are supposed to.

I wish somebody made some nice looking polished stainless rim screws, maybe button head ones. I've only seen silver mr gasket or gold looking moroso ones. I asked ARP at a PRI show why they didn't make any, they said no demand, I think they would sell.

Hey guys, I just finally got around to pick up a set.. lol. Holy crap these screws are huge. Can anyone confirm that I bought the right size. I checked on summit and they are selling the same size but Jesus Christ I'm not driving a Top Fuel car.
My screws are 1/4" in diameter by 3/4" long. I drilled the holes with a 13/64" drill bit. I haven't put them in yet but just want to be sure they are the right size. I think they are but just want some re-assurance. Thanks. -Mark
