Here is my friends car. He has a big tire on the car but is still peels back from the bead at high speed. Bead locks are required for cars 200 mph or faster.
Screws will hold just fine.

there are plenty of damaged, wrecked small tire cars and current information that would prove that 15-yr old 200-mph theory dead wrong. the OP is dead accurate with what he posted.

Its not a myth, is an NHRA rule. So what did all the fast cars do before beadlocks? We raced Comp Eliminator in the 80s and there were no bead locks. We all ran rim screws.

the wheel is to wide for the tire...

the tread should be equal or a bit wider that the rim width...tires grow with speed and having tall series sidewalls...there's a reason for bead locks

Yep!!

I know some TAFC's that run Hoosiers, have no bead
locks. Not sure what they use to keep the
tire on the rim.

they use inner liners, here is some reading material on wheels http://www.dragzine.com/tech-stories/wheels-tires/the-411-on-drag-racing-wheel-technology/

20lbs heavier, but look cool as [Edited by Moparts - Family Friendly Site - Keep it clean] and easier to change tires.

Bob, ur exactly right, they do look cool. And Charlie has beadlocks, and said the same thing, they are SLOW!

Pretty common practice with the true 10.5 and 8.5 stuff to run a wheel widerthan the tire tread width. I have NEVER seen it as an issue. Our tires are always installed BY the manufacter at the track. In fact M/T suggests a larger size wheel to increase the footprint. Some folks just dont get it.
Al, most of our slicks probably do the same thing on a wheel the size of the tread or bigger, we just never saw it,lol. Hense the 20 rim screws per side on his wheels!

Great article. Thanks. Only thing it doesn't really address is tire to rim width. Does a great job explaining the different styles/ methods of tire to rim attachments, proper usage and limitations.

X2....

and your definition of larger size is....... and is it outside the tire manufacturers suggested ( ???? ) minimum / maximum rim width for that tire??? Ya, I don't get it, but I'm open for a valid explaination on just how a wider rim increases a tire foot print. Guess I'm just missing - something .

Perhaps some of you replying here to the post should actually get out got the track and ask the manufacturers what they suggest for these tires in these types of applications. I do and have I also race one of these cars. The same class as the video is from. We all run 12" wheels as suggested we do from the manufacturer of the tire M/T for a 29.5x10.5 tire. On the outlaw 8.5 tire we use a 10"'wide rim as suggested by the tire techs from M/T.

The reasoning behind why we do has been pointed out here already. We get a bigger footprint and can run more air in the tires. But you can just read them catalogs and use those conservative recommendations. For those of us trying to truly maximize our programs we will continue to work with all the manufacturers to get the most we can from our cars.

Ok, just looks unsafe to me. If you gotta run glue and a zillion rim screws ( 16 per side is the max they suggest ), I think bead locks would be in order. I would sacrifice a tenth or two and go with bead locks. I'm not that brave. I admire anyone who "pushes the envelope" - safely. JMO.
