Ok I'm getting 15x6.5 wheels

Stock tires are 185x65x15 and I was going to get those, but would the extra 1 or 2cm in width be worth it to go up to 195x60 or 205x60?

195x60x15 would make my speedometer .96% too fast.
205x60x15 would make my speedometer .96% too slow.

Would either of those other sizes have an effect on acceleration or anything? The difference in diameter is like 1/10 of an inch, but who knows. Is it worth changing tire size to get an extra 1 or 2cm of width (195 and 205, respectively), or should I keep the stock size and have a speedometer error of 0%.

What's the widest section width and tread width that will fit on our cars?

Thanks for the input.

none that would be noticable. Less then 1%.....

now if you went to a 205/50-15 then you may see a difference.
For mine its almost a 6% difference in tires size (Small) which give me a little bit of a boost in acceleration.

What about tread width and section width? The 205's have a section width of 8.2 and a tread width of 6.7. Will that fit or would it rub?

I have a Falken Azenis in 205/50-15 and they dont rub, and the Tread width on the Azenis is wider then many 225's

Alright cool. Cuz one of those articles I read that was at a site that you linked to in your "Brake Myths" post was talking about how all these 205's of different companies were different sizes and some of the rubbed. I'd be pissed if I bought all this stuff and then it rubbed.

So I guess I'll go with the 205/60/15s.

Finally I made a decision

Can 195/60/14 fit on our vics? I got the 14" hubbies and goin back to stock for winter, but I need new tires for them. Would that tire size be ok?
