I'm heading back to my favorite place, KSC shuttle runway, to make my third effort to break 200+ in a mile and maybe 205-210 in the 2 mile plus runs. I've been thinking about maybe changing to a taller tire since I put in the 3.21 differential gears which got me to 189.8 in the mile and 200.588 in the 2+ mile. The max the transmission 5th gear (0.80), differential gearing (3.21), 355-30-19 tires will allow for is 201.4 MPH at 6350 RPMs. The tire I'm looking at is a 345/45-19, lets me use my stock wheel size and should get me to max of 209.7. Any thoughts on other options that might be out there?
