RE: low profile tires
if you are still trying to get performance out of the car go 17's or a racing 18. if just for looks go 18's. when i had my stock 16's i could tear up 2nd but after getting my 18's it cut down the 2nd grab tremendously.

Try to keep the rolling diameter as close to stock as possible.

This should be stated in large font on every site that sells rims and tires, it should also be stated at shops that sell the same thing.
I don't know how folks can stand having a speedo showing slower or faster than their actual speed or should I say GPS speed?

RE: low profile tires
a good rule of thumb for plus size rims is that for every step up you go in rim size, you should drop one tire size:
(EX.) P 205 / 60 / R 15
The P represents the sort of tire you have, most of the cars on this board with the exception of the SUV's will have P, or Passenger tires. LT's, or Light Truck tires commonly go on the SUV's.
The first set of numbers before the slash, in this example, 205, is the width of the tire's tread patch in millimeters. In this example, the tire's contact patch at the manufacturer specified pressure and load capacity will be 205mm.
The middle number after the first slash, in the example, 60, refers to the sidewall height in a percentage to the tire's width (the first number). So in this case, the tire's sidewall height is 60% of the tire's width. Keep in mind that this number will be directly affected by the first, so not every tire that has a middle number of "60" will be the same height.
After the last slash in most cases, you will see a letter, either "B" or "R". This is to indicate how the tire is constructed, whether it is a Bias tire or Radial tire. Most tires used on passenger vehicles are radially constructed.
The final number, in this case, a 15 is representative of the rim size.
Lest say your factory rim is 15" and you want a 17" wheel, that's 2 sizes up, so your tire's sidewall height should go down by 2. Say that your factory tire size on those 15" rims was a 205/60/15, the appropriate size on your new 17" rim would be a 205/40/17 (or slightly wider depending on the width of the aftermarket rim).
Just some general info about tires for ya there
