Snow Tires

Hey, I have a question about some snow tires I have from a different car. The tires on my Cobalt are 195/60 R15 and I have these snow tires that are 185/60 R15. Does anyone know if they will work on my car? Will they fit on the rims with no problems? Has anyone ever put a different size tire on a rim and had problems with them?

These snow tires aren't being used, they belong to my dad and they were for his old car, he's since gotten a new car and I'd like to use the tires this winter.

Thanks
Tom

It will throw your speedometer off a bit. Maybe less than 2%. You will be going 59 when reading 60mph or 98 when reading 100Kph.

185 is the width of the belt in mm's or 7.3''
60 is percentage of belt for side wall height in mm's or 4.37''
so total height for a 185r60/15 is 23.74''
a 195 will be slightly taller at 24.21''

That doesn't seem like much of a problem, they are snow tires so they won't be on all the time. As long as they will fit on the rims with no problems then I'll be happy.

This will not cause any performance problems at all. I prefer going with a narrower tire with higher wall like 185-65/15 because this makes for slightly more weight per square inch on the pavement and it cuts through snow instead of trying to go over it.

How much of a difference is that do you figure?

If you meant going from 195-60/15 to 185-65/15 it would be 1% off.

(195/25.4*.6*2)+15 over (185/25.4*.65*2)+15= .98943%

So at 98.9 mph on your speedometer you would actually be going 100. Your needle is wider than the difference.

If I were you I would use your dads tires if the price is right. ha ha lol. Otherwise they might just roth and take up room in his garage. Recycle and save a rubber tree plant.

I never said 185/60/15's, what I said was 185/65/15's are a good substitute for 195/60/15's.

I just purchased a set of Hankook (i*pike) winter tires today. It has an aggressive snow thread but still quiet on the road because of the ''V'' shape thread.
