Fast Facts for September 16-17, 2022
Tire: Goodyear Eagle 18-inch Speedway Radials

Set limits: Cup: 1 set for practice, 1 set for qualifying and 10 sets for the race (9 race sets plus 1 set transferred from qualifying)

Tire Codes: Left-side — D-5170; Right-side — D-5172

Storyline – Several factors impact tires at Bristol: The NASCAR Cup Series wraps up the first round of its playoffs this weekend at Bristol Motor Speedway, and both teams and tires will endure a tough challenge. The concrete surface at Bristol is hard on tires and will change continually as the race goes on over 500 laps. Because of the speeds and loads, Goodyear designs the construction of its tires for Bristol to align with other speedways, not the short tracks that the half-mile length would suggest. From a tread compound standpoint, the key for Goodyear is to lay rubber on the concrete surface. That, combined with the fact that the PJ1 grip compound will be applied to the bottom several feet of the racing surface in both corners, will allow drivers to move up the track to find alternate grooves as they search for grip.

“Bristol is undoubtedly a challenge across the board,” said Greg Stucker, Goodyear’s director of racing. “We have done a good job with bringing a set-up that rubbers-in the track and allows for multiple racing grooves. Bristol has had a recent history of using PJ1 in the corners, so that ‘preferred’ groove takes rubber fairly quickly. The progressive banking and the search for fresh concrete will have teams moving up the track, which potentially leads to more passing and better racing.”

Notes – Cup teams on Pocono left-side and unique right-side at Bristol: Having moved to an 18-inch bead diameter tire for 2022, NASCAR Cup teams will run a different tire set-up than those in the Xfinity and Truck Series at Bristol this week . . . this is the same left-side tire Cup teams ran at Pocono in July . . . this is the first time these teams have run this right-side tire code . . . in addition to the obvious construction changes to what Cup teams ran at last year’s race on the Bristol concrete, these two tire codes feature compound changes, which will give the cars more grip . . . with this 18-inch tire, and its lower profile sidewall, NASCAR Cup cars will not run inner liners in any of their tires in 2022.

I bet there's some folks at that campground still talking about the kiddie pool.

I hope they can get the top worked in and it not be a bottom only groove all weekend. It never came in for the truck race and still not there for Xfinity practice.

Maybe tonight's race will help the top come in. *fingers crossed*

This race might be a snoozer based on the lack of lap time falloff

Chase slow as s%#& again. The second we get to the playoffs we are just terrible. Getting out qualified by Almirola and AJ at Bristol. Just unbelievable

Car definitely isn't where he wants it yet but drawing group A was definitely working against him. Car got faster and faster for everyone after him. The entire group B was stupid fast.

I'm sure he will wreck out being mired in the back and that'll end the playoff run. Just abysmal work by the entire team this entire first round. Not deserving of another championship IMO

It's odd. They're off by a mile.

Chase didn't have top 10 pace at Kansas. Strategizy and a good lane draw paid off for stage points, but when the field stretched out and stage 3 happened, he just barely made it to the top 10.

There's a bit of concern.

Bowman looks real fast too, again.

We've never had a regular season champ elimated round 1

It’s like the order of speed flipped instantly at Hendrick when the playoffs started
