Competition Dinky rims/ tires

[Rhondasway]

So, what's the lowdown on running under-sized meat on the track? Is there a down side (other than all the laughter? )

Is this considered "cheating", as it's not what the truck runs on the street? Any DHRA -specific rules?

Thanks guys!Oo.

Eric McBride aka Stack'd-N-Jack'd & Diesel Sport Promotions runs itty bitty tires and wheels at the track. Check his column in issue 38 there is a picture of him spooling up waiting to race.

Nothing in the rules about sticking out wa-a-a-a-y past the fenderwells, like a ghetto rollerskate?

So I can run 38's with 16. 5" rims on the street, and then run low profile 17's perofrmance tires at the track ???



Just wantin' to know.



1/16" tread depth on the street tires?? Oops,, better replace mine,, Too many burnouts

 

[DHRA]

Absolutely Merrick. The 38's wouldn't be very desireable on the track anyway.
