Default RE: Changing tire question

ORIGINAL: ink003

the two sets are as follows:
winter = 235/50/18
summer/front = 245/40/19; summer/rear = 275/40/19

i just hit up that calculator, and even at 75 mph, it only seems to beabout 1mph off.

but then again, i didn't compare them to the stock 17"s since that's what the speedomoter was originally calibrated to - hmmm, maybe it's even worse...
I've got 275/40 19s in the rear of mine, and it's off about 1mph not enough to mess with it.
