I'm running 275/60's on 15x10 vette rally's now,27.5 is what they measured out to be
I'm tracking on the 410's,I found a limited slip with 373's,the guy said he still has it for sale but won't contact me back so I guess he don't want to sell it that bad,410's would bring to life but I know it's a heavy *** truck as well,like to have a little bit of cruising without winding it out to awfully much,still has the 4l60e as of now so I still have od

I'm running 4.56s in my Silverado 2500 4x4 with 31 inch tires.. It's not bad with the od.

4.10 isnt too much for highway use. Ive run the same gear on the same tire and the same trans. 4.10 on 28" tire is what most guys run

Kinda depends on what kind of driving mainly. On a DD 3.73s for me with that short of a tire but I do drive 70-75 a lot. Had 3.90s with 29s, 4.10s with 32s and loved them also but again I have to do a lot of highway around DFW. If mainly street then by all means 4.10s or more!
Going from 3.42s to 4.10s went from 9.54 to 8.90 on one truck. On another, 3.42s to 3.90s felt like 50 hp.
