Tyre slip on the Rim

(1/3) > >>

Rat:
We are about to fit new tyres on the Halibrands 8) we have, obviously we don't want to use bead screws, any suggestions to help limit tyre slip on the rim. Thanks

THE FRENCHTOWN FLYER:
Clean the tire beads and rims with solvent before pressurizing the slick.
At the suggestion of another altered driver I stopped using bead screws years ago. We don't use tubes. Neither of us have ever had problems.Tire pressures in the 5 - 6 psi range.
It might be interesting to mark the tire and rim to give you confidence.

Rat:
Thanks Flyer, I was planning on marking the tyre position. Any particular reason for not using tubes.

wideopen231:
a ton of weight added with tubes.

Yes
Rotational weight has a much greater effect on performance than static weight in the car. A pound of weight on the tire circumference has about the same effect on performance as ten pounds in the chassis (fun fact: on a bicycle with most of the weight at the outer periphery the ratio is about 16:1.)
