I run 305/45/18 nt555r in the rear full time. Ran them with 4.88's short of 2 years and my current 4.56's.

I run the 26", but I want to try some 28" tires just to see the difference at the track. I find the 26" a bit short for my truck. I have 3:92's, so with the 26" tire I blow through 1st and 2nd pretty quick at the track, but if I had 2P upshifts like you 4th gens, it might be perfect.

I run a 305/45/18 mt street radial but it's a 29.5 in drag radial, I'm changing to a 305/35r/18 which is a 27" and I think it should show a little improvement in my 60' and my et being that I run at the 1/8th mile track 99.9 % of the time

I run 275/40/17 with my 3.55 gears. Seems like it wants to go through too many gears with that small of a tire though. I will try again with a transmission that isn't junk this year.

The real ? Is what rpm do you cross the traps in 4th?then you can have a better idea on what tire you need.imo

I ran 275/40/17 (25" dr) on mine with 3.55 gears it hooks really well.

You wouldn't want to be at full redline crossing the traps, would you? Most street vehicles run out of balls before redline. Do the Hemis continue to build power all the way?

That sounds like a good number. What are your times and other mods? OP has 4.10s, so he would need a 30-31" DR to be in this range? Do they make a DR that tall?
