Didn't know my tires look so wide

chobit

My set of winter tires came in today from tirerack.

For winter tires, my rear tire size drop from 295 to 265, but both looks very wide, especially when they are out from the car.

My previous STi had 225, then I went up to 245 which was already pretty wide...!

Anyway, here I some photos I took today when changed my tires.

The previous owner changed them from 305 to 295 because the 295 has a little more thread to start with.  As for my snow tires, they are sottozero series II, and I bought them with Wheels.  They are anything great and light, but looks pretty good.  Total for less than $1700 wheels + tires-

Yeah.. I used to go there too!!  but only for Alignments!

Where do you guys go to install tires?  Any recommendation?

Nah.. I don't mind driving in the snow..  I already down size to 265 from 295, the front is 235.. so I'll see.

I think traction on 265 snow should be better than all season narrow tire....,  !  My STi was on 225, and it was ok..

and I mistaken the rotor as tire occassionally...!!

Those are not tires, those are rotors! !LOL I know you don't have a choice, just like my boss's G37S ...

IMHO, I think winter tires are better choice and would be money well spent.

That's unless you only stay within Richmond, where everything is 100% Flat, and avoid snow driving most of the time.

There are different types of Winter tires, Some are maximize for deep snow & ice, while others are maximize for light snow, rain/wet road condition similar to what we get in the Pacific NW.

For example, my previous Dunlop M3 (new replacement are callled Dunlop 3D) are performance winter tires, which are designed for very good dry weather traction, but excellent water/rain, and good snow/ice conditions.

Since you can save some milage from using your summer or all season during winter with your winter tires, your regular tires would last you longer.  In the end, they aren't really costing that much more than driving with just your summer or all season.

Catpiano.  While many people think that winter driving is not that bad in Vancouver, I totally disagree.

Alberta is very cold in the winter, but it also keep the snow very dry and powder like instead of turning into ice quickly, then snow are clean-up by trunk before it gets a chance to turn into ice.  While in Vancouver, snow/rain usually get melt during the day, then form a good layer of ice overnight, and they are cleanup for at least a week.  The amount of traction is just less with these black ice with a good layer of water sits on top.

It is easier to get yourself going + easier to control on AWD w/good traction control, but weak tires still wouldn't cut it, especially when it comes to stopping.
Check out this link from tire rack comparing summer/all season/winter tires on ice:

At the end of the day, your winter tires can probably save your car from a costly accident.  Getting out of control in slow speed hitting a curb would probably cost you a rim, control arm or alignment, and that cost more than a set of winter.

Again, I don't claim to be an expert, but years ago, when I still have my Jeep Grand Cherokee, I would purposely driving anywhere with snow locally in Vancouver, or go 4x4 off road in the mountain with fresh snow, and ice, etc..!  (Using BFG all Terrain Tires only).  Then, once I get a chance to put on some snow tires on my 06 Subaru, I can already see night and day difference with snow tires, I highly doubt I would ever drive in the winter w/o winter tires.

Here is some good info about M+S tires vs Snowflake symbol: http://www.tirerack.com/winter/tech/techpage.jsp?techid=125

Also found this site with a review on summer/all season/winter tires test on not just snow, but hot dry & wet condition.

BTW, here is my other theory.

Let's say the amount of traction goes from 0-10 (higher is better)

An average driver can maintain their driving pretty well in all condition with traction index of 5.
index of 8 of above you can push the car pretty well
index of 3 it's very difficult to drive

On warm/dry condtion:  All tires provide enough traction
summer = 10
all season = 9
winter = 8
Note: Anyone can drive well since the worst winter tires still provide enough traction for easy driving.

On warm/wet condtion:
summer = 8
all season = 7
winter = 7
Note: Anyone can drive well since the worst winter tires still provide enough traction for easy driving, but you don't push the car as much in the corner.

On cold/dry
summer = 5
all season = 7
winter = 7
Note: Anyone can drive well since the worst winter tires still provide enough traction for easy driving


on cold/wet
summer = 4.5
all season = 6
winter = 7
Note: Summer tires no longer provide good enough traction, but all season and winter tires still provide enough traction for easy driving.

on cold/snow/ice
summer = 0
all season = 2.5
winter = 3.5
Note: Summer tires simply don't work, all season provide some traction, and even winter tires won't allow easy driving, because it's far more difficult to drive in the snow/ice condtion.

So, my big idea is, any tires can probably proforms relatively well in any condition, but cold/snow/ice, which even with the best fitting tires, still isn't easy.

yeah.. u r right about hot/summer with winter tires.. =D Thanks!!

and summer tires at 7C/44F is exactly what the minimal rating on summer tires.  Once it get down to around 5c or below.. it does get very hard, and slide quite a bit..!  That's kind of what we have in the winter here in Vancouver/Seattle...! 2-4c in the morning.. for many months..

From my racing experience, summer tires are still grippier in both the cold and the wet than all sea ...
