More questions about rims

[Slip]

i never really thought the larger the rims, the slower acceleration would be... but how big a difference would 18 and 19 inch rims make as compared to 17? because if it takes off a second or so, i think i'd just go with 17's... maybe 18's in the back

This is new to me
If you have a 17" tire and a 18" tire, both with the same tire height to match the stock odometer, how can acceleration be slower?

Rim diameter alone won't necessarily affect acceleration. Depending on the rubber you put on the rim, tire height may or may not change. The biggest affect will be from the fact that with a larger rim, you are typically turning more wheel and tire. If you are turning more weight and your horsepower remains the same, your acceleration will suffer. If you are pumping out enough horespower (say 350+) that the extra rotational weight isn't a factor, then the increased tire size will actually help acceleration because the larger contact patch will give you better grip and you are less likely to spin them. All that being said, unless you are planning on taking the car to the strip, don't worry about the acceleration loss, go with what looks and rides best.

Just making sure you know that 19" rims aren't going to ride very well at all.

.......can you tell by now that 19/20" rims are for MR2's and civics and ricers that don't know any better?

stock rims and tire ride on about 5 inches of sidewall(235-55-16's). guys running 275-40-17 tires with 17x9 WS6/Firehawk/ect. are running on about 4.45 inches of sidewall height. just the loss of .55" of sidewall made a seat-of-the-pants difference. ride quality suffered some, even tho handling kicked *** . to keep the stock wheel/tire diameter on 19's, u'd have about 3.5" of sidewall. that's not very much, u'd feel a lot of bumps and such. also, with that big of a rim, the width or the rim is way out on the outside, adding rotational mass, making it so that u lose more hp as ur mph increases.
