technicalities here.... but are you aiming for outright accelleration or just acceleration to 62mph?
technically the smaller the rolling radius and wider the track, the better the accelleration will be...
however I maintain that I could get to 62mph faster with my 205/40/17's purely 'cos it was all 1st and 2nd... now I have to change up around 59mph...
technicalities aside: if you keep the rolling radius the same and you're not losing traction (through silly-narrow wheel width) then accelleration should stay largely the same, unless of course you're going for cheap (heavy) alloys.... in which case it'll be like trying to accelerate with half a case of beer on each corner.
