Tuesday Tech Question (10/22)

The Tuesday Tech Question is a fun section where prospective technical inspectors or anyone who wants to get a better idea of how to work the NHRA Rulebook can test their knowledge and search abilities. If you have an NHRA Rulebook, try and find the answer to the question in the book before looking down at the answer. If you don’t have a Rulebook but are an NHRA Member, you can download a pdf at nhra.com under ‘Member Benefits’.

I am just finishing up my ’41 Willys Top Sportsman car.  I noticed that some cars in the class have beadlock wheels and others do not.  What kind of wheels do I need to purchase?

Beadlock Bill


Beadlock Bill,

If you plan to run 6.50 or quicker or 210 mph or faster you will need to have SFI Spec 15.1 wheels.  These wheels must either be beadlocks or have liners.  For more information, please see General Regulations Section 5 in your 2013 NHRA Rulebook.
