Winter tire size? Options

[reko]

I know i'm supposed to use 205 55R15 on my stock alloy wheels but i have a HUGHE deal for 4 brand new winter tires for 100$ from a co-worker but thing is they are 185 70R15...

I know that I can use 195 60R15 but will the 185's be ok?

if you were to calculate your tire's Outside Diameter (OD) from the specs.
Your OEM tires are 205/55/15 which has an OD of 23.88

185/70/15 will have an OD of 25.20 inches = +1.32inches difference
195/60/15 will have an OD of 24.21 inches = +0.33inches difference

When I went to Kaltires they told me they like to stay within 0.4 inches of OEM in order for the speedometer to not be way off.

For 185/70/15 your speedo will tell you you’re going slower than you are. Which might equate to more speeding tickets if you're not careful.

Fitment wise maybe someone on here more knowledgeable can tell you if it’ll rub or not.
