During NASCAR Cup Series practice at Las Vegas Motor Speedway, tire issues were appearing as teams once again pushed the envelope on air pressures. It doesn't help that Vegas also features a nasty bump in Turns 1 and 2 where cars often bottom out.
Two cars ultimately crashed in Turns 1 and 2, and they were both Fords -- the No. 4 Front Row Motorsports Ford of Noah Gragson, and the No. 21 Wood Brothers Racing Ford of Josh Berry, who suffered a really big shunt.
