No question that 26 by 8.5 is too big for 90 percent of the SRT-4 apps. I would go with the 24.5 by 8.2. If your spinning the slick you need to work on your burnout or your track is not prepped correctly. When I was running mustangs in the late 80s the 26 x 8.5 netted me 1.5 shorts at 11 flat so that size is very capable at about 11 psi. Its just too tall for the SRT. You will lose 3-5 mph if you arent running in the 400 whp range or higher.
Now a taller tire is almost equivalent to a taller gear. Forced induction cars love tall gears, as it gives them more work to do, thus increasing the MPH at the trap. I've seen this myself. Are you suggesting that the "sweet spot" for the srt happens better with the 24.5? I could almost go for that, but I think with a properly tuned S3 car, the 26 would add MPH, but possibly slow down the short time.

currently running 26/8.5/15 m&h slicks on k1's....stock turbo no n2o 296whp 364wtq....pulled my best 60's 330's 1/8th's 1000ft's and 1/4's....car is way more consistant now. MPH is off only from 1/8 -1/4 about 1mph but the consistancy is un matchable so far. 1.672 60is best and 11.87 best 1/4 115.37 being best mph to date.

I remember reading a post from Dr. Who about using different size slicks on the lightweight stage 3 car. Raced the Stage 3 PVO car tonight There is the post. On 22" slicks they were able to trap 121 a couple times. On the 24.5 the trap speed didn't slow down that much (less than 1mph), but lower the ETs. Not sure if they ever ran a 26" slick, but it would be interesting to see the results.
Also with the 24.5" slicks you would not need to shift into 5th gear unless you are trapping 130ish
yeah i have the 26 8.5 x 15 ..i think the tire is to wide mine rub on my shock i have to run a spacer so it wont rub ... my next set is gonna be 24.5 x 8 15 .. the 8.5 is to wide...
i also have a prob spinnin with the 26 x8.5 x15 in 1st gear ...i launch the car at 3000 rpm i run 14lbs in the tires .... im ruffly at 26lbs of boost
my whp is at about 340 on (pump gas) 390 on (race fuel)...

Just for reference, what wheel are you running? Stock strut or coilovers?
