We screw our slicks to the rim. We found out with the AA/SA car that the slicks moved on the rim if we didn't.

I've run a best of 1.17 60 foot on 32 x 13.5 Hoosier Radial slicks with my current 3130 lb. ride and a best of 1.28 60 foot on 30 x 10.5 Hooiser Radial slicks with my former 3880 lb. ride and the tires have never been screwed to the rim and I make north of 200 passes a season.

I also haven't swapped my tires side to side in over 10 years and my 60 foots are deadly consistent varying thousanths on any given day from pass to pass.

That said, walk the stock/super stock pits at any divisional and national event and you'll see the vast majority of those going rounds, winning races and championships do not have their tires screwed to the rim including the the winningest car in NHRA history.

Have your slicks mounted dry, meaning no soap/mounting lubricant. Yes they will move on the rim for a few passes which doesn't effect consistency nor is it anything to be oncerned about.

Ed, if these were new wheels, I'd take your advice and try to run them screwless. These are old Center Lines that have holes already drilled in them, so I'll screw them.

"sand" blast the bead areas with 80 grit aluminum oxide such as Harbor Freight sells cheaply. If you have trouble with the wheels squirming on the brake drums or hubs, blast those areas too.

When I was going to try the TOYO tires the rep I talked to recommended no bigger than a 9" rim. He said the sidewall was made to work on a narrower rim. When I raced my car I never had rim screws and it was a stick shift 3205lbs 7000rpm launch 3.19 first gear 5.57 rear. It would move the tire an inch or so every 6 passes then I would swap sides.

I wish I knew that before I bought these 10 inch rims. These weren't easy to find.

I talked to a Toyo distributor when they had the 2 for 1 sale and he cautioned me that a lot of the tires were 2-4 years old.

[Ron Gusack]

These are 07's, if you go by the last 2 digits. They didn't hook worth a damn tonight. Some of the problem is the track, but it's mostly me.

Ron, you could also try a compound called bead sealer that tire shops use. It is a tar like compound that is sticky and works well to keep tires from moving at all. it is messy to put on but easy clean-up once it dries. you just have to resist the urge to wipe it up while it is still wet. comes as brush-in-can like anti-seize compound.

Hoosier also says no wider that 10" wheels for my 10.5" radials, but 11.5" wheels made it a new car. I have mentioned that to two different Hoosier reps, both seemed very surprised. Absoluty no more "radial wobble". It's quicker, faster and likes more air in the tires.
