Rim Screw Question
 

Hello

Would like to get some advice on if wheel screws are needed in my application. I?m finishing up a nostalgia drag car and purchased a pair of Bogart Steelie Dan aluminum wheels for the back. I?d prefer not to install screws but want to make sure the car is safe with a stick shift launch.

Race weight is 3,000#
G101a 3.08 1st gear
4.88 rear
Anticipate 1.25 60ft
M/T 29.5x 9 (3056ST) tire

Wondering if sandblasting the bead (they need to be powder coated) , and/or high tack is enough, or if I need to suck it up and drill the wheels.

Re: Rim Screw Question
 

I have been OK with sandblasting the bead area of steel wheels, and no lube on the tire beads when installing them. I run 4.57 rear, 3.08 Jerico, 1.5 60' for comparison. Car is a few hundred pounds heavier than yours.

We glue ours to vintage NOS Cragar SS with Permatex Hi-Tack. Messy job but the results are worth it. 1969 W-31, 3700 pounds, 3.08 Jerico, 4.88s. Been plenty of 1.53-.1.55 60’. Same tire 3056ST.

Glued ours on for demo derby car. Steel and aluminum rims.

Will you be running tubeless, or using tubes in the slicks? How high will you be launching, RPMwise? On my bracket car, I am running slick screws, best of 1.29 60 foot, with 2 step low side at 62-6600 RPM. Have ran both Jerico DR4s (3.19 low), and currently a G101A (also 3.19 low), now running a RAM Billet 10"/Black Magic Defiant clutch, but also used McLeod Soft Loks for many years. I am currently using tubes, but mostly ran without tubes until last season. With tubes, I would absolutely run the screws, if the tire moves on the rim enough, it can rip the valve stem off the tube, which is NOT a good thing. On my old 85 Mustang, I ran the 9x29 1/2 3056ST M/T slicks, and did not use tubes, or screws, but that car only went a best of 1.36 60 foots, and mid to low 10s in the 1/4 mile. If you are expecting 1.25 60 foots, that should be well into the mid 9s, I would imagine, if it was me, I would be screwing the tires to the wheels. Huge difference in a mid 1.2 60 foot compared to mid 1.5s.

I bought a set of Weld wheels, and Hoosier recommended that I have the beads knurled to eliminate the use of wheel screws.. works just fine on my SG car.. check into it before drilling..
