And some of us continue to beat a dead horse:(

Thanks Mr. Norm.:( there are one or two guys here who thrive on the conflirt.

Don't thank me Gar-I was talking about you:D:D:D:D:o:o

I am on vacation and do not choose to play mental ping pong.... Thanks to all of the positive responses, and I am sorry for those that continue to be unproductive...

I know you were norm, I was just trying to deflect it towards those who keep picking at it!B).

Oh what does great leader know from productive, he's holding the hand of the biggest peck, uh picker!:D

With regards to "tire wear"....a minimum diameter IS a useful rule. Foam tire wear with regularity and I also race in other hardbody series with similar rules. Mid-America rules allow just under one inch fronts (0.950") ,closer to 25mm. Rear foam tires can wear significantly even with the lower power motors the club uses. Normal wear and tear should allow at least a 26mm rear tire prior to replacement.

Just got a set of NEW H&R silicone wheels: 26mm(x 12mm) fronts and 27mm rears is what they measure.
