One of my main questions is tire growth/roll out. With my 10.5 x 29.5's running quarter mile i hit my 7500 high side chip roughly 8.5 seconds into the run. These tires are 95" RO (me measuring them). The 10.0 PBR are 94.5 on the MT web site.

Racers say the PBR's dont't grow at all. So am i looking at riding the chip for 3 seconds

Running on the chip is illegal. This is essentially what they referred to as a 'stutter box' decades ago.

Look out for the high side chip Nazi Micheal. I had posted I hit the limiter during a time run & above is his reply.

The M/T 29.5 x 10.5 PBR is my primary radial, I also use the Hoosier 9 X 30 radials. Radials have come a long way & I have no reason(s) to go back to bias ply slicks. I've been on radials for 10+ years.

My PBRs are a true 30" diameter/94" RO. The tread measures 10"s wide. They're very heavy coming in at 34 lbs. each. When I switch back & forth to my lightweight Hoosiers there's little to no difference in performance. The Hoosiers are 8 lbs. lighter than the M/Ts PBRs.

As for the growth they don't grow much & you will be on the chip longer. IMO, I would not like to be on the chip that long.

I had to get spacers to put behind the beadlock rings for the radials.
