On a somewhat more serious note, and for those who may not be aware...but Paul Gage has developed a few new moulds made specifically to fit over the NSR air ride wheels.
He’s got 2 new sizes, 20105LMDF and a 21105LMDF. The latter size being one of the two spec , hand out tires sizes for the Tourist Trophy.
Both of these two new tires have 2 channels within that the raised portion of the NSR air ride wheel will slip into. The tire then essentially fills the gap between these two raised flanges on the air ride wheel.

This is the best solution I’ve seen outside of trying to put foam or o-rings within the “gap” to help get the tire to seat evenly. Now no need for the fuss, just slip the tire on, glue and true as you normally would :-)
I had the privilege of doing some early testing with these new DF’s and have to say they work a treat! Well done to Paul :text-bravo:
