Incorrect my man!
It does make it a smig taller but its almost not noticable.
Its about .4-.7" taller and wont notice it on the speedo.
You can have a 295/45 be wider than a 305/30.

yes it will, just slightly
your original size is 245/45, which means your sidewall is 45% of 245mm
sidewall-- 4.3 in ~ 110.2 mm
radius----12.8 in ~ 326.2 mm
diameter--25.7 in ~ 652.3 mm
circ.-----80.7 in ~ 2049.3 mm
revs/mile-785.0
so with 255/45 your side wall is 45% of 255mm
sidewall---4.5 in ~ 114.8 mm
radius----13.0 in ~ 330.6 mm
diameter--26.0 in ~ 661.3 mm
circ.-----81.8 in ~ 2077.5 mm
revs/mile-778.0

Alright, so just a little higher. Ok. For whatever reason, it looked taller than just .3", but I think it was all in my mind. Thanks everyone for your answers.

it's a much bigger issue when you calculate everything that it entails going from 245-45 to 255-45; This small change at what you can call a mere .3 inches will make your ABS/Emergency Brake light go off if you're running 285/40 and larger. Just a heads up.
