I was wanting to know, I already have OEM rays 19" rims with the sport package. I wanted a 2nd set of rims for winter tires and just swap them during winter.

I found a good deal but a little hesitant to buy them,

500 for 4 OEM Rays chrome 19" rims, with tires on them. But 2 need to be replaced ASAP he said.

But I also wanted to know, can I put 225's on the rear? Its a 245 rear rim, but was wanting to cheap out a bit for the snow tires and get 4 225 tires, or is it better to spend the extra 40-100$ on the proper rear width?

 

If you can afford it, why not just get the right size?

 

Because some tire shops have advised undersizing the rear assists in snow.

Thats why I am asking.

Wanted more information on the subject than what I have found.

 

Narrower tires are definitely more beneficial in snow. I don't think it would be a huge issue going down in width a bit, just wondering.

 

What about sidewall height?

Currently running 19's, but hear that smaller rims help too.

i can use 17's and 18's.

Just want to know whats best before committing to rims.

And I read an article from Car and Driver showing top snow tire brands doing horrible in rain, dry, and cold weather. But only doing better than all-seasons in snow and ice.

 

I would keep everything as close to OEM height for the wheels and tires as possible to avoid throwing off your speedo and whatnot. If you size down your wheels, size up the sidewall height.

Winter/snow tires are intended for colder, snowy weather. All-seasons can perform fairly well in most driving conditions but they are not the best in each condition. If you don't get a ton of snow you might just need a good all-season tire.
