Hey all,

So this is my first car. So it's going to be my first Winter!

I was wondering what setup of tires should I use?

Front : 225/50-17
Rear : 235/50-17

???

Can i change those size like 225/50-17 on all 4 wheels? What do you guys have? What is recommended? I live in montreal, where winter is pretty CRAPPY!

Please help!

Thanks!

The correct sizes to keep the OEM stagger is 225/50/17 front.....235/50/17 rear.

If you want to go with all 4 tires being the same size.....then go with 225/55/17. The 225/50 is about an inch smaller in diamter than the rear...I believe its 25.8.
On the 235/50 or 225/55/17 its very close to the OEM rear size...the rear diameter is almost 26.9"

I did 4 225/55/17 Dunlop Winter Sport M3 tires on 17" rims. This will keep the rear tire diameter within 3% of the original size(s). With this set up I had no problems with the VDC/ABS systems, I believe it throws off the speedometer slightly( showing actual slower speed by 2mph), and I am still able to rotate the tires each season to extend tread life. The Dunlops worked well for me in a couple of Big Snows we had two years ago.....

I wouldn't go any smaller with the rear diameter.....then you may have trouble setting off the systems.

 

Excellent,

For tires, i thought of going with either yokohama ice guard ig20 or toyo garit kx. I heard alot of good for those tires.

Seems like Dunlop m3 are very popular around here.

Thanks!

 

Any one else has a different setup or recommend the same setup?

I think I will go with 4 same size tires.

 

I am in a similar position just bought the G35 a few weeks ago, and live in WI.

I already had 18" alloy wheels Kazera KZ-V with Pirelli WinterSport 240 tires which I used on my Altima SE-R. So for my new G35 setup, with staggering (rear is 1" larger), I have the following:

Front: Pair of KZ-V 18"x7.5 Rims with Pirelli WinterSport 240's at 225/45VR18
Rear: Pair of KZ-V 18"x7.5 Rims with Bridgestone Blizzak LM-25's at 225/50HR18

The rear winter setup is not wider as stock, and also H-rated vs. V-rated on the front. Unless I wanted to buy a set of 4-new rims with wider rear rim's, this was my option.

I should have gone with a set of 4 Blizzaks' or Pirelli's. However, Pirelli didn't make 225/50R18s and Blizzak's would have been rated V on the front which I already have, so no use wasting a set of tires. The local Tire Rack recommended installer that I have used for a few years now said that since G35 is not a 4wd vehicle, no need to match front and rear, only axle matching needs to be done, and if anything try to make the rear less narrow to help cut though snow, which I have done by sticking to 225's vs 245's on rear.

Also I used:

http://www.miata.net/garage/tirecalc.html

to do some calculations before making my purchase decisions, and these were the results:
Front: 225/40R19 to 225/45R18 --> +0.4% difference
Rear: 235/40R19 to 225/50R18 --> -0.5% difference

I could not find any tire combination that will make it exact to the stock.

Tire Rack wanted me to sell me wider rims for the back, but I tired these rims on without a problem on frotn and rear. Not sure if they will fit the brembo models though. Then they wouldn't ship my order for 2 blizzak's because I didn't buy a set of 4, so I had to call and yell at them to ship the order.

When I used the Wintersports for the last 2 winters in WI, they held out very well, the problem really is cold temperature more than snow/ice. (summer tires harden way too much and winter tires are softer.). I drive about 2000-2500 miles a month and really will just try and avoid those ~10 snow days. My experience is that I enjoyed having the 18" ally wheels rather than 17" because most cold days are just that .... cold not snow covered and the Perilli's held to about 80% of the performance of the Potenza's.

So get 18"s and if you are going to buy a set of wheels too, save the extra $$ and buy narrower rims and match tires as necessary.

d pak,
Most tire dealers recommend you use the same brand type tire front and rear....this is to maximize your handling and traction capabilities, and ensure no problems triggering the VDC/ABS systems....Most places won't sell you two different brand/tread types because of that.

The 17" rims are preferred because of the larger side wall for traction in snow.

The 18's will fit fine, but I believe you will be better off price wise to go with the 17" set up.

See the attached pic of my 17" Snow set up

 

17" x 7.5 wheels with 225/50-17 front, 225/55-17 rear on Dunlop Winter Sport M3's. Great combo.

 

Oh i see,
225/50/17 in front like whats the OEM recommends.

So I'd only need to change the rear to 225/55/17.

For winter, I don't really care about performance. I'm not a speed maniac. Actually, I drive slow. Don't want to kill myself by slipping on ice.

I was wondering, if michelin X-Ice would do the job. or Yokohama AVS winter.

Considering my style of driving.

 

Right, 225/50-17 and 225/55-17 are almost exactly the same diameter as my OEM 225/45-18 fr and 245/45-18 rear. Plus, for winter tires, it's better to go slightly narrower, as it cuts down on aquaplaning in the snow/slush.

And the higher performance winter tires are not for driving faster on ice and snow, but rather for when the road dries out during the winter; you still want a tire with a decent speed rating and sidewall stiffness, or else the car will feel really squishy when the road is dry.

 

I have a set of 18's just the rubber forsale if your interested. I really liked the setup. Of course, I would still get track control on, and drive like an old lady, but these guys got me around in the winter. One time in a really bad ice storm too
