stock size is 195/65-14 but some people recomend going with a 205/60-14, how would that change the handling of the car? right now i have bfgoodrich traction t/a tires and i will probably get the same, but wasnt sure about changing tire size.

That's a drastic tire size change. Your motor and tranny will soon be dead.

its not a huge change in width but to a point, wider tires are better


the difference will come in switching from a 65 to a 60 profile tire as that will change your actual speed vs what your speedo reads due to a change in the number of rotations a minute.

so go with a 205/65/14 and youll be straight

if he goes with the 205-65-14, it'll make his car feel a bit more fat and sluggish b/c of the higher sidewall.

going with your original idea of 60 series tires is fine. it'll be slightly wider, and still feel somewhat the same handling wise.

You can figure it out yourself, its pretty striaghtforward math.

XXX/XXRXX

XXX is width in mm's
/XX is aspect ratio, or the percentage of the XXX that tells you how tall the sidewall is
RXX is the diamter of the rim

So your orginal 195/65R14 is ~24" overall diameter. As long as you stay within 5-8% of that overall diameter you will be fine. For example:

205/60R14 is ~23.6"
215/60R14 is ~24.1"

[NO]

195/65 and 205/60 are probably very close in overall diameter

the profile is the sidewall height expressed as a % of tread width

ok i know all of this so far
what i was wondering was if wrapping a slightly wider tire onto the rim will result in a less responsive sidewall and thus sloppy steering feel.

i see where he is coming from. it would make a difference if you weren't dropping the profile down a size. it's not a drastic increase in tire size anyway. your sidewall will still be pretty much straight (not angled out like i think you're thinking).

slightly less responsive because the sidewall is being pulled in more from the tread to the bead. shouldn't be noticeable in this case, though.

i might still go with the 205. the tire i want in a 195 has 5 tread bands but the 205 has 6, so it looks better and ive read a little better in the rain.

^how narrow is that?

here is my review: i like them, they are grippy and a great price. only down side is they are a little noisy during more spirited driving.
