Default Tire Sizes

Ok Im real dumb when it comes to rim and tire sizes but what sizes do you guys have on your car? Im thinkin either 17 inch 5ZIGEN FNO1RCs or 18s of the same type. What would you recomend? To me it seems that 17s are more for performance and 18s are more for show but my friends seem to think otherwise.

Also could somone explain the tire size format? How do i match a rim size to the correct tire size?

Thanks for the help!

Yeah I wouldnt go over 17's. Anything past that makes your tires too slim.

http://www.miata.net/garage/tirecalc.html check this page out it might be kind of helpfull. I wouldn't go below 40 series tires.

205/45/17
205: tire width
45: percentage of above width will equal the sidewall height.
17: rim diameter

If they could get it, most people on Nabisco seem to prefer the 17X8.5, which gives them a little stiffer sidewall ('cause it's smaller), and allows them to wear the big 235's they all love. Unfortunately, few wheels come in this size, so most peeps end up with 17X7.5 or 17X8.

If you speak of 18's the Nabisco Performance Secret Service will be after you in a heartbeat, but pay them no mind, they're full of it. I wonder what they all said when the S203 specs came out and it showed the beautiful BBS RE's in 18X8.5, probably nothing. While it's true that adding unsprung weight/rotational mass is not the best of things, get what you like, just be conscious if the weight. If you can, try to keep the total weight at each corner under 43 lbs, which isn't too hard if you pick the right tire.

17 by7.5 or 17 by 8 is the way to go on a sedan. Us wagon guys are kind of screwy, i use 17 by 7 wheels with tires that have a width of 225.

...a 17x8 with a 235/40 or 245/40 is great.......a 17x8.5 starts getting a bit heavier...but the 255/40 is better on the 17x8.5


I just put 235/40's on 17x7.5's and the min recommended wheel width is 8 inches for that tire.
