Need some input from the board

[G37 Man]

Looking to go from 08 G37 Coup to 09 G37 Coup/Sedan AWD.

Can anyone shed some opinion on what to expect as far asperformance difference,ride and overall looks?

I do not have a second car and without dedicated snowsI will not be going out with summer performance tires andyes I can buy 4 snows but to switch back and forth every yearI feel is not worth it.

The extreme option is to buy a 2nd car but then I would notbe driving the G 37 all the time and I would be heart broken!

Will you be driving it to the point you NEED summer only tires???We recently traded for a 08 G35X that has brand new tires that DO NOT show up on Tirerack as replacement tires, but are rated pretty good in snow by CR!!!They are only performance M&S as opposed to summer only tires.

I only expect to do some spirited driving in it. Rolling WOT and pushing it a bit in the twisties. So far, it's been great!!!! It also has 17's....didn't want anything more either!!!

It all depends on how you will be driving it. I'm willing to sacrifice some 'ultra performance' for some snow traction.

Don't know if that helps, just my opinion.

I had an X for 3 winters now 4th coming. I don't really liked the idea to switch tires 2 times a year. Few reasons why. Nobody can argue the snow tires are the best in snow. However they have a bad side. Even in cold weather they not as good as a good all season tire when the road is dry or only wet. For me that is the deal braking to get snow tires. You have to look at the number of days it snowing vs. number of days not.

AWD will help you at accelerating and turning in wet and snow. I hit big snow piles when I ended up shaving the snow and the X did not stop for a bit. Even when I stopped it in big snow and started it did get out without any effort. However at braking AWD will do nothing more than RWD. But AWD with summer tires in snow almost as bad as rwd with summer tires.

There is no perfect solution since winter tires will suffer(braking) at dry/wet road in winter and gives you really good braking in snow.All season will suffer at braking in snow but gives you better braking and cornering at wet and dry cold days.

Hope this helps

Here is an article winter tires vs all season tires on a RWD G35. It shows few snowtires on the G35 and all season tires in wet/dry and snow in cold. It shows the braking and skidpad #'s. Intersting #'s.

Its not uncommon for people to have the concern. I just don't drive my car and take my wife's 4Runner when there is a lot of snow or I expect snow on the roads.

I see 4 options:

1. Buy a seperate set of rims and mount snow tires (you can often find a combo used with tires for cheap)

2. See if there are available snow tires that will fit your rims. Most tire shops will store the winter tires for you when you buy them from them.

3. Change to all season tires.

4. Drive slow and careful when there is snow on the ground. You shouldn't have a lot of issues because the AWD system rocks. Just realize you have to brake sooner and turn slower.

Personally, I'd be fine with #4. I drive MUCH MUCH slower if there is snow on the roads.

My Problem Journey coup with 19" tires different size front and back.They only offer one 19" dedicated snows according to Tire Rack with no all season available.

I have been told that car is programmed with the 19" and to move to the 18"all season is okay but not sure what impact it will have on the computer program.

To get 18" All Season,I need to get rims,tires and sensors,when you add it up it gets real expensive for 4 tires.

BTW thanks for the input

check out the Toyo Proxes 4. They offer a 19" All season.

what is the stock size tire? I'm running 245/35/19 which you can get the proxes 4's in.

depending on the offset of your rims, but I know that some people can run 255/35/19 all around. That would be slightly closer to stock.

Stock size

Larger brake calipers up front with sport model,I believe offset is 42mm

have you looked into the TOYO Versado LX

M+S rated and AA traction rated

http://www.toyo.com/tire/pattern/versado-lx

with a 40k warranty...

[G37 Man]

They only come 18" largest size? I was told the revolutions of the axle for the G37S would need a 19" tire or it could impact the computer settings is that true?

I guess this is a question for our resident Infiniti expert,help!

[tollboothwilley]

those aren't offered in a 19"

[AZhitman]

You don't HAVE to stick with a 19" tire.

Buy the 18's, but make sure you buy a size that has the same overall diameter as your OEM 19's.

Tire Rack has specs on ALL the tires they sell, so it's easy to look up the size you'll need.

Plus, you get the benefit of a slightly taller sidewall.

Going 4 toyo m/s Proxes same size on all corners to match the specs needed on the car.Going with 225x50 18 W rated Performance A/S

decided to have them mounted on separate rims and leave my summer performance tires on their rims for use in warmer weather.

I love the G37S too much not to keep it !

Thanks for all the hlp
