should i put these tires on my car?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

right now i have p215/60r16's on my car i can get free used
p225's in same size would it be ok to put these on? i figure 10 mm isn't gonna make much of a difference...so is this a bad idea?<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>?

10mm isn't THAT big a deal, but it's nice to have the extra traction; generally moving to larger (wider) tires is seen as a performance mod, unless they're some shit rubber. What's stopping you!?!? If I had free 205s to replace my 195s I'd jump on 'em straight away! Heck if I could squeeze 215s onto my 6.5 (or 6"?) stock steel wheels, I'd do it!

Basically, go for it unless it's a bad/cheap/damaged set of tires.  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

Otherwise, you could just switch the rears to 225 and keep 215s up front.

BTW isn't the  215/60 R16 a little big? as in, doesn't the huge sidewall look kinda funny? I think the "proper" 225 size should be 225/50/ 16, or at least 225/55 16... but 225/60? Just sounds kind of like a big sidewall.

if you have the oem 16x6.5 wheels i would recommend against it. a 225 section width should be complimented with a 50 aspect ratio. and 225 is too big to put on 6.5 wide wheels. how do i know? i did it. yes it will go on the wheel, and no it will not be damaged, but handling will not be optimal. i only had 225's on a 6.5 for a while because i knew i was going to get 7.5 wide wheels eventually. and even then, 8 inch would be better with 225's.

If your wheels are 7 inches or wider, I would get 225/50/16.

If they are smaller than 7, i wouldnt get a wider tire.

I am running 225/50/16 Toyo Proxies FZ4 all around and they are fine on my 7" rims. They fit the rim nicely unlike my friend with the same tires squeezed onto a 6.5" rim there is a hella lot of sidewall sticking over the lip.

Quick tire lesson in case you don't know how to read a tire

195/60HR15 87H -- stock size for an s13

195 - width measured in mm
60 - Height as a percentage of width
60% X 195mm = 117mm sidewall
H - speed rating
R - radial tire
15 - rim size
87 - weight rating
H - speed rating

according to my calculations (unless your stock tire size is different than mine, ie s14) the proper upgrade sizes would be as follows

205/55r15
215/55r15
225/50r15

205/50r16
215/50r16 (this is slightly tall)
215/45r16 (slightly short tire)
225/45r16

anyway, you get the idea. for a better representation of what happens, go to this web page:
