still yet another tire/wheel question

[joemaine]

getting ready for a Maine winter... got rid of my Jag x-type for a great deal on a 2010 Genesis, I still have the snows (Blizzak LM-60 225/45/17 - less than 2500 miles) from the Jag. I'm guessing that the sidewall height is not right for the Genesis if I downsize the rims for the winter...but wanted to check in with the community to see if I'm correct.

If I do need to buy new Blizzak's, is a 225/55/17 the best 17" size? What's the best 18" tire size (if I don't downsize the wheel)? The Genesis is a 3.8 'premium' - do I need to be concerned about wheel offsets?

Here is the online calculator, just make that "speedo error" doesn't go beyond 3% or it might trigger traction control sensor, iirc. At least it was the case in bmw 5 series.

Looks like the LM-60s go on craigslist - too bad; I thought they were great snow tires.

Now to determine if I should drop to 17" (225/55/17??, and if I need special wheels/offsets), or find out the best size 18" snow ??/??/18.

If I drop to 17"... which is better:
6.5 x17 (w/215/60/17 or ?)
7.5 x 17 (w/225/55/17 or ?)

...any comments from the community on the best place to pick up wheels, and any special considerations for offset/etc.

Post the specs of your OEM wheels and we'll go from there. (225/45/18) ?

I believe I have stock wheels currently with Milestar 235/50/18 (the tires were new and came with the car)

Thanks for your attention to a new user/owner.

...looking for an inexpensive wheel (if I downsize) - are there any thoughts on this 17" wheel from Tire Rack?
