use 185/60/r15 specs for good drive or 195/60/r15 for the most u should go. i have 185/60/15 rims and michelin energy tyres in my car and they do thgr8 but steering is a bit heavy.
for acceleration iam afraid thats how aweful acceleration of this car but by the time u would have driven 3500 kilometers u will be habitual to it.
although u can ask ur honda dealer at 1000 inspection they increase acceleration a bit but later it re adjusted to the standard as currently is.
