In case you ever try to dismount one, you'll need in the least an impact gun powered bead breaker. Most tire trucks use a hydraulic powered one and some way to muscle the tire around (very heavy). Just wait until you have to buy new ones. I just paid just under 5 for 4 bias R1's. Radials are more and I don't mean 5 bucks either, I mean $5,000.00 not including mounting or tubes. All in I was just north of 5.
