I think it's affecting all the paddles not just ultralights. I've tried to get any type of skat trak and have been unable too!

 

I spoke with somebody at Skat-Trak about a week ago and that was what he told me. I am not 100% sure he knew exactly what he was talking about.

As far as finding tires, try contacting Jim's Sand Toys at (580) 824-2021.

 

I can make a call tommrow but my impression is that the difference between regular and superlites/tripple buffs is only the amount of buffing, if they can't buy the tire size anymore......
