but if we had a bigger tire we could easily get more out of them. I had more issues spinning on the top end of the track this year than on the launch. Maybe Pat should make us run 8" tires instead of 9" in lieu of pully adjustments all the time LOL

Maybe not exactly what you are looking for but we run 29.5x10.5 stiff sidewall M/T's on the NA heads up car. I also run them on my 64 which is 3644 with me in it. The heads up car is 2740 and we have been 1.06 60' with it and it repeats like a bracket car with that tire. My 64 has been 1.20 but usually its 1.3x becuase its tripping it with something other than the front tire.

I have no doubt you could get more out of them with bigger tires. I was just pointing out that you dont need big tires to make a fast car work

How about a low horsepower stocker and I'll use U/SA as an example. Will a car like this benefit by using a tire smaller than a 9x30?

The Gremlin uses a 26 X 9 bias plias in T/SA.....9 x 30 would allow for a lower rear gear, not sure I would pick up much there even with the radial, I have run a 26X9 radial MT in the car, seemed exactly the same.....now the new 26 X 8ish bracket radial from hoosier might just be the ticket for best et.

I wanted to try. Only found 9x28
Someone had 8x26 but afraid a gear change is needed.
