NEW tire question...I promise

[6902Stangs]

Found a deal on 255/40/17 Nittos. I'm pairing them up with 275/40/17 in the back again...great tires! Does anyone know how much of a difference the 40 aspect ratio will have compared to the 45? (Actual sight, not theory) Not a big fan of bad tire sizes on cars. Thanks

They are 25" in diameter compared to the 25.7" of the 275/40/17 and stock sized 245/45/17 tire

a 275/40/17 tire depending on the brandand desing of the tire can actually match the sotcks tires overall diameter
