ok newb question, but i was told to ask around by my uncle before tossing these on (I won't myself, just bying them)

What kind of things can i see with getting a little bit bigger tires? I have 195-55-15's right now.. I know my Speedo will be a little slow, which is fine because its a little high right now (like 1mph or so) so thats alright, but I was told there could be a bunch of other problems and im just curious what i might see so i know ahead of time.. :-D

Thanks for the responses in advance.. ya'll are always so helpful smile.gif

Edit: its a 2000 tib, bone stock :x

 

go with 205-50.
You will see better tracting smile.gif

 

205/50R15's
THAT is the correct size, the 55 profile will be too tall

That will still only affect the speedo which has already been stated to not be an issue.

Other than the speedo being off you MIGHT have some rubbing issues when you turn hard or hit a bump. Really not a big deal cause you've got so much rubber on there but I wouldn't risk it.

Why must you go bigger?? Sale at the tire shop or something?? wink1.gif

 

the wide the better traction smile.gif

 

im running 205's on my tibby, and could easily run 215's with no issues

 

Mmmkay, I always get my numbers mixed up with those tire codes. 205 = wider 55 = taller Gotcha.

 

yes.. the first number is the section width of the tire.. how wide the tread is in Millimetres.. The second number is the aspect ration.. how tall the sidewall is in COMPARISON to the section width. The third number, of course, is rim diametre.

so.. a 205/50/15 would be:

205 mm across at the great with the sidewall HALF that at 102.5 and it would be running on a 15 inch rim.

 

If you went with the wider 205/50/15 you can expect better cornering, handling and acceleration.

 

but shittier traction and handling in the snow
