Rim screws

drace69 · 08-26-2011, 02:43 PM

I know this has been debated before but I am wondering again.

Getting new set of rims for the car and I was wondering if I really need to have screws in the beads. (not going to drill the new rims if I don't need to).

What is everyone's experience with when you need these?

My application is a '69 Mustang set-up like a stocker - calc-tracs & mono-leaf.

Run a 10" rim with a 28 X11.5 tire - tubeless - usually around 12 - 13 PSI.

Car has been a best of 1.33 60' - but normally high 1.30's to low 1.40's for 60'

ET is low 10's

Any insight is greatly appreciated.

I went through a similar issue but i only ran 9 lbs of air and the tire was slipping on the rim..i would mark the tire at the valve stem and see if it moves any after 10 runs or so..any movement will cause inconsistencys

Sandblast the bead areas of the wheels with 80 grit aluminum oxide media, such as Harbor Freight carries. I did the same to the mating areas of wheels, brake drums, axle flanges after bending all ten 1/2" grade 8 bolts ("studs"), but still went to 5/8".
