Tubeless tire pressure

Myron Piatek · 06-06-2015, 11:39 PM

I've heard pressures from 14 to 25+ lbs from 9" tire racers. Lot's of variables, but most seem to be in the high teen to low 20 range. I have Hoosier 9"X 30" Lightweight Radial Slicks at 21 lbs on a 10" rim, car weighing 3,540 and footbraking. Wider rims allow more pressure and radials seem to like a little more than bias ply. I fine-tuned it by watching if contact is being made all the way across the tread (may need less if not) or if rubber is being laid over the side (may need more).
