for front.
rear's are -2.0"section & -2.5"tread mounted (-1.0"sec. -1.25"tread per side)
Rim lips will stick out further than tire sidewall.
better fit (still a tad stretched/but better) 245/45 Front & 275/40 rear......*remember* the overall wheel lip is 1" wider than the bead (or advertised wheel width)
9=10" & 10.5=11.5",,,,this is very close on all wheels.
