Small Tire vs Big Tire?

Even though they are bias ply, they only weigh 16lbs a tire, versus about 25lbs for the radials I had, so they were a bit faster. Oddly enough, when the track prep was iffy(test and tune nights mostly), the car would go faster, especially when it would turn the tire about a quarter to half turn off the line. I was also crazy enough to run at most 30psi in the 26x8 bias plys if I really was "going for it."

You forgot to tell him you ran a27inch front tire!
