A275/40/17"s 25.6" diameter, Give or take a miniscule amount between manufactures.

If you stay with a replacement tire that is 25.6" diameter, you will not have to recalibrate REGUARDLESS of series, rim width or diameter of wheel.

Well, as long as BFG T/A KDWs NT in 275/40R17 is that diameter, i am good to go. Should have the rims on sometime next week, when everything comes in.
