Before buying winter tires, I would like to know if a person can put on a different size tire.

I have 225/50R17 on it right now. Can I go with a tire like a 225/60R16, for example?

If so, anybody have any advise on where I guy can get an extra set of rims for the 16 inch tires?

Thanks,
Gerald

You cannot safely fit 16" tires on a 17" rim. 17" rim requires 17" tires.

The best thing to do would be to get a set of 16" steel rims.
Right now you have the 225/50/17, the standard size of the base G6 with 16" rims is a 215/60/16, which is a 1.15% difference in diameter compared to what you have now. I decided to go with 205/60/16's because the diameter difference is only 0.66%, they are also slightly cheaper.
With the 205/60/16's on, the GPS and the spedo are exactly the same to atleast 90mph (145kmh ish).
Either size would be good, most companies seem to reccomend staying under +/- 3% diameter difference. The larger +/- the size difference, the more the spedo will be off of how fast you are actually going.
Here's what I use to compare sizes

May I ask why you want to go down to a 16" tire? I personally put Continental Extremecontact DWS 225-50-17's on my fiance's 08 GT. I am very happy with the grip and ride of the tire wet and dry, but the sidewall on the tires are a little on the soft side.

I was able to get a set 4 of Michelin X-Ice with 2 seasons left on them with 4 steel rims for $250.
Looking at it now, prob should have gotten 17's so I have the option to get bigger rotors/calipers, but it was a great deal.

I was told that a 16 inch tire may cut the snow a little better. We have a lot of ice and snow up here, so thought I would try it.

To improve traction in the snow, the narrower the tire the better.
Best fit would be 205/60-16 or 205/55-17.

I have another car as well. 2009 Vibe GT with 18 inch tires

Any idea what i can use on that one for a winter tire size?

Thanks

with the right rims im sure you could do 17

What size do you have now?
Everywhere I check, the 09 Vibe GT has 17's
Once you figure out what you have now, pop the size into
Tire Size Calculator and play with teh sizes, keeping in mind that you want to stay under +/- 3%, ideally under +/- 1%
