Tire Question?????

[cagefightmma]

I just got rid of my stock 17" wheels w/ 235/55/17 tires. I am putting on new 20" Saleens, 20" X 9" front and 20" X 10" in the rears. My question is regarding what to set on my SCT X3 programmer to make sure my speedometer reads correctly.

Factory Tires (235/55/17)......742 revolutions/mile
fronts (265/35/20)................739 revs/mile
rears (275/35/20).................731 revs/mile

Anyone know what setting to program????
Thanks,
Roger

Crap, actually the fronts are 265/35/20 at 739 revs/mile. Is the setting still 730??
