6.0 LS2 (9.5:1 comp)
Terminator X Max
4L80E, Yank SC Series 3000 stall
3.73, True Trac
295/40/20 Nitto 555 G2 (29.3" tall) on 10" wide wheels
The thing is... besides the traction issue, I really enjoy the truck the way it is so am not looking for major modifications right now (tubs, new suspension, etc) so am starting with the obvious upgrade of tires and was looking at these
Mickey Thompson ET Street S/S:
305/35/20s (28.4 tall x 12 wide)
305/45/20s (30.8 tall x 12 wide)
MT Tech Support says either of these are fine on a 10” wide wheel.
and
M&H Drag Radials:
275/40/20s (28.7 tall x 10.8 wide). 10” wheel ok
305/35/20s (28.4 tall x 12 wide). 11” wheel required so these are out
Seems like the MT 305/45s are the obvious choice, but what do you think? Any other options I should look at? Do you think I’m wasting my time trying to keep the 20 x 10s?
Lots of experience here, so appreciate any/all feedback on traction upgrades that don't require going full-race mode

My thought is tooo much low end torque for a truck that has no weight in the rear. I know a larger diameter exhaust helps reduce low end torque some. Taller tires, lower gears such as 3.08's and/or different stall converter.
