Using a taller than stock tire has a few hidden benefits; on 8 tooth trannys the speedo gear moves into the Lower range than the usual region.
Bigger tire= smaller gear.
I'm running a purple gear with my setup; a 3.55 is as big as I can go with these tires.
225/55-16 and 225/60-15 are almost the same size...
