I just bought a 2005 MT G35 coupe with the sports tuned suspension. It currently has 19' rims with P225/40R19W front tires, P245/45R19W rear tires. But I live in NJ and need to get winter tires.

Now my questions is, do I get 19 inch snow tires and just have the mechanic take the summer tires off and put the winter tires on the 19' inch wheels or should I get 17' rims and winter tires?

I found somebody selling these size rims with new snow tires:
17" X 7", 5 LUGS on 114.3mm with 45MM OFFSET

Will these fit on my car? How do they get installed? Can I just jack up the car, take the 19's off and put these on?

I am new to this so any input is greatly appreciated, thank you.

 

Double check your current tire size, stock in back is 40 profile, not 45. Not the end of the world if that's what it is, but keep that in mind when it comes time to replace.

Strongly recommend a separate set of wheels for many reasons:
- saves wear and tear on your 19's both in mount/remount dings and road salt
- you'll want your winter setup to be skinnier for better snow carving and the 19" Rays won't go very skinny
- 17's or even 18's will be cheaper which is important to consider since snow tires don't get used past 35-ish % wear

I run oem coupe 17's for my winters. I jack one wheel at a time using air gun for removal and torque wrench for install. Original RE92A all seasons up front and currently using some Toyo performance winters out back. Stock staggered size, but most run non staggered. If I had to do it again, I'd go the tirerack route with premounted snow tires at least on the rear. Probably with 18's because I hate how borring the car looks on 17's compared to the gorgeous 19's Rays.

I'm not an offset expert so I'll leave that to others but you do need to know the tire size that's coming with those wheels. You don't want that to be too far off from stock which is 225/50/17 and 235/50/17.

 

since i have all 4 summer tires on now, I would have to get all snow tires. The thing is if I order the 18' snow tires from tirerack.com, then i have to get 18in rims also. I kind of wanted to look for somebody selling OEM rims.

But as far as the tire size, this is all like a different language to me...like i said, I am new to this.

 

The great thing about the tirerack route is you enter in your car information and then they spit back wheel/tire packages that are guaranteed to fit and not cause VDC issues. A lot of people buy 17" ASA wheels with snow tires shipped for less than $1000 from them.

 

Most effective, cost and function wise, will be the 17's. Tire selection will be better, more protection to the wheels against pothole damage, and more aggressive compounds in the smaller size. Call me to discuss options!
