Went to this track in the fall and fell in love. Great event! Already have hotel booked for this fall's race!

Possible snow flurries Wednesday evening at the track... want snow? Just send NASCAR.

I was impressed with the view of this track when I went too, and plan on going back.

This date is a tad early for mild sunny Vegas, another couple weeks and it'd be perfect. Should start to clear up weather wise toward Saturday though, good horsepower weather.
 
Should be a good tripleheader weekend I like the 1 hour of practice (they need 15 more minutes), qualifying, race setup they have going.

Maybe more of those hauler parades the 1st day to keep graphic designers busy.
 
In a bizarre turn of events I get to come to this race now! Whoo whoo! Unfortunately I can't do my regular job of ski instructing as I have a foot infection. Walking isn't pleasant but it's tolerable. We're bringing crutches just in case!
 
Goodyear Fast Facts – Las Vegas

Tire Codes: Left-side — D-5186; Right-side — D-5190

Storyline – Vegas is a temperature sensitive race track: Las Vegas Motor Speedway has traditionally not produced much tire wear, but that has slowly started to change over the past few years. However, there is another factor that has played into that upon a deeper look. Over the last several races at the 1.5-mile speedway, the warmer the ambient temperature – and, by extension, the warmer the track temperature – the more tire wear teams will see. With warmer temps, grip goes down a bit, leading to more lateral slip with the heavy Cup cars and more tire wear. When the temperature is cooler, the cars are more “in the track” and, therefore, wear tires less. The difference in temperature could lead to a one second variance in lap time fall-off – approximately one second per lap over the course of a fuel run on a cool day vs. two seconds on a warm day.

“After many years being considered a low tire wear track, wear has actually started to increase at Las Vegas recently,” said Greg Stucker. “The package that Cup teams run on these mile-and-a-half tracks with the Next Gen car can generate a good deal of lateral slip, especially if the track temperatures are elevated on a hot or sunny day. Those conditions will lead to more tire wear.”

Notes – Cup cars on Fontana tire set-up at Vegas: Being on the 18-inch bead diameter tire, NASCAR Cup teams will run a different tire set-up than those in the Xfinity and Craftsman Truck Series at Las Vegas this week . . . this is the same combination of left- and right-side tires that Cup teams ran at Las Vegas last September . . . they also ran this same tire set-up at Fontana last weekend . . . last season, in addition to Las Vegas-2, Cup teams ran this set-up at the fall Kansas and Texas races . . . with this 18-inch tire, and its lower profile sidewall, NASCAR Cup cars will not run inner liners in any of their tires in 2023.
 
hey @SlicedBread22 what do you think of the 22 for the vegas race?

I love it. As others have said reminds me of the old steve park car.
Now we need a valvoline 6 a Havoline 28 and a quakerstate 26
 
Truck race will be interesting.... temperatures in the low 50s, pretty much perfect for maximum grip.

Also of note is high winds for Saturday and Sunday during race time, a little stronger on Saturday. 25mph sustained with 35mph gusts o_O
 
^Monster Energy man Kirk Bush should be on the mic for this one!

Truck teams need to get to get Vegas first , a lot of them are stuck on I-40 because its closed due to the winter storm, they were supposed to park today at 3p local but that didnt happen.
