"cheater slicks"

Me too.

I run the Nitto 555 275/60-15 on 15x7 Centerline AutoDrags on my Duster. This will be the 3rd summer and they are holding up nicely. Excellent street traction. I run 30psi street, 25 strip.
I have experience with the Nitto and the M/T drag radials. Based on a bunch of time slips, (but no actual same day comparisons) my impression is the Nittos are slightly softer, and maybe hook out of the hole a little better, but the M/T's work better on a decently prepped track. I can't get much more than 5000 miles out of either one, but I'm not really trying to either, if you get my drift... :)
I don't think a half inch narrower wheel will make any difference at all.
Thank you men! It's looking like I might just go ahead and save the $120 and get the nitto's... they won't ship out till Monday anyway so I've got the rest of the day to hear a better argument LOL. Somehow I do prefer Summit over Jegs. Not that one has given me trouble over the other, but maybe I can have Summit match Jegs no extra fee for oversized shipping?
