3.5/22.0-15 (Skinnies) D.O.T. Certified
? Spare is a 15x4 wheel, aren't most frontrunners set up for 15x4s?

Just make sure that your skinny spare setups don't weigh more than a 185/60/14 or what not on a factory wheel.
Reduced rolling resistance is great and all but not at the expense of more weight.
Learned this decades ago when I would spent Wednesday night's at Sears Point.

Who can can weigh a 15 spare and report back?

That's interesting. My comments were based on my perception that NB1 compact spares were 15's, same as Andrew.
However, I just looked at mine and the indication is that it is 14 x 4.
this NB2 is 15x4

Front Skinnies: If I end up ponying up the $$ for biased ply skinnies:
How much would it matter between the M&H 3.6/24-15 vs 3.5/22-15?
Pros and cons, assuming no special suspension tuning.

Im thinking these 24.5" tall on a 15x8 6ul for my rears.
I think it will be a close fit. Don't wrinkle walls "grow" by the end of the quarter mile? It says tire diameter range: 24-24.99 inches

Mickey Thompsons dont grow much. Some tires are built to grow as you get down the track. These days, most drag racers try to keep tire growth to a minimum.

You say you are expecting 325/325tq on a boosted v6. You might pull off the larger tire with the right diff ratio, depending upon launch technique and torque at launch versus when the boost comes on. Sounds like unchartered territory and trial runs to figure it out.

Im thinking 5 speed + 4.3 with at 24.5" tire puts me at 122mph on the limiter in 4th which should be good for an 11 sec pass.
Compared to a 23" tire 4th gear is only good for 115mph and I'd have to shift to 5th
Edit: assuming the drivetrain stays together after launch*

So, I may have jumped ahead of myself. Orders some wheels and tires. Racing slicks. Now I look at Atlanta Dragway (nearest to me) and I'm not sure there is a class that I can race in. They have also reduced their Test and Tune days.
The best class would have been TrueStreet, but for that, must be DOT tires. I haven't found any cheater slicks small enough.
Need a track that is friendly to "imports", I guess.

Most tracks do test and tune one or two days a week.
If you are just starting to try drag racing, you will be better off with biased ply slicks. DOT tires are a bit less forgiving and require more time to get the setup all working properly. I really think you will be happy with the tires you originally picked out. Dont over think it.

Would allow me to test and tune, and also run TrueStreet in same set-up.
