The K/GL lakester is in tech at WOS, it would have to be pre 2008, cause I didn't have that embrella that year, it got run over I think in 2007. The tent was handed down to MC tech in 2008, and the lakester would not be in MC tech. In 2007 the record for that class was 149 and change. Can you tell the tires are actually MC tires from the picture? Do you know what year the MC tire rule came about, I believe it was after a car incident years after that picture was taken. Why stir the pot when the facts aren't really known?
The proper procedure was followed, and the proper answer has been given. Lets dig up a picture from the early 50s' and question why we have to run with roll cages, these guys didn't.
There is language in the rule book concerning tires. ( Have you read the rule book Steve? ) Anyway. . . that language (section 2.F Tires:) does not say anything that would imply that motorcycle tires may not be used on cars. It does say that if you want to run non-rated tires, or aircraft tires, or a reproduction of vintage automobile or motorcycle tire . . . . . that you need to get approval from the contest board 45 days prior to an event. The way that that one sentence is worded about reproduction tires makes it somewhat confusing about the MC tire . . .is it refering to all motorcycle tires or just reproductions of vintage motorcycle tires? . . . In any case there is nothing that specifically says 'no motorcycle tires on cars.'
The photos were from a few years back but they weren't from "the early 50s' " And yes, I can tell that the tires are motorcycle tires from looking at the photos. I have other photos of that car because I felt it was unique and had many interesting features so I copied several photos to my conputer for later reference. Would you like me to post another picture showing a closer view of one of the tires? In another post you said I posted old pictures to " . . insinuate the officials are selective on who the rules apply to." Where did I say that Steve?
In any case my intent was not to 'stir the pot.' or to 'insinuate the officials are selective on who the rules apply to.' My intent in posting the photos was to show that at least one car in recent history has run with bike tires. I had hoped that would generate some discussion on the pros and cons of using bike tires on cars. There are issues that can cause problems. Generally speaking, motorcycle tires have a different bead contour than car tires. So mounting bike tires on wheels designed for car tires is both difficult and dangerous. This can be overcome (I am told) by having wheels built that are designed to hold bike tire beads. Maybe someone with actual experience doing this can chime in here.
The hoped for advantages in running motorcycle tires is reduced rolling resistance and a narrower profile than car tires. Assuming adaquate speed rating and load ratings, motorcycle tires can offer a price advantage over some car racing tires.

Soooo. . . .
You asked " Do you know what year the MC tire rule came about?" My answer is "No." More specifically . ."what MC tire rule?"
You said, " . . . I believe it was after a car incident years after that picture was taken." To which I ask, "what car incident?" More specifically, . . what car incident involving a car running MC tires that had an incident caused by using MC tires on a car?
You asked "Why stir the pot when the facts aren't really known?" My answer is "If we don't know the facts how else do we find the answers?"
Don't get me wrong, I think the SCTA is a excellant organization, manned with first rate men and women that work hard to sustain and advance the sport of land speed racing. But there could be improvements in communicating with the general LSR public. The SCTA rule book is pretty darn good. But the vast variety of classes, car and motorcycle models, technical advancements, and evolving safety requiremnts make it impossible to publish a rule book that can cover everything.
And I know that this forum is not the official way of getting SCTA technical, class and safety rule clarifications. If you have an SCTA rules question go to section 16 in the SCTA rule book and contact the appropriate representative to get your answer. I've done this a few times over the years. Each time I've done this has always resulted in getting a prompt and complete response. No problem.
But there is a problem . . . when one person asks one question and gets one answer . . . only that one person knows that answer. It would help the whole LSR community if those questions and answers could be put out to the public. This might sound like more work for the SCTA. But it might prove to be less work in the long run because it saves re-answering the same question over and over.
