I use the dunlop graspic tires. I dig em. they're great, they've lasted 2 winters so far, and it makes my 924S handle like a mountain goat in the snow...

as for the dry, meh, nothing braggable, but hey, I don't expect to do any massive cornering on them, nor do I normally break 90 MPH... so it's not a big deal... I keep an extra set of wheels with my summer tires and switch em out whenever it's done snowing for the season... and I've been caught off gaurd before... that' aint fun... driving from Grand Juntion to Denver in a white out with summer tires... I didn't slide once, but everyone else did... I was amazed...

 

does 205 seem alittle skimpy? ESPECIALLY for an S2? my 2.5 would spin 205s without much effort.

 

I thought the thinner the snow/ice tire, the better it is. Fat tires do badly in snow and ice...thinner footprint = better grip.

 

They work well for drag radials. I have heard it is the economic drag radial. If thats true or not I don't know.

 

Here's another question:

In very cold and dry weather, which tires work better--High performance summer tires, All season tires, or winter tires? In other words, do summer tires get stiff and lame in cold temps, or only in the snow?

 

I asked this question once and was told that, as a general rule, by the time you get below 40*F, the rubber in summer performance tires begins to harden and it's not too long before snow tires actually grip better, all other things equal.

I'm confused. Why would you want an all-season? (ContiExtreme) I don't know anything about the ContiExtreme, but I don't think I could ever buy tires that claimed to have "Shark Fin Bio-Mechanics." They didn't do too well in the TireRack test anyhow - mind you, I'm one of those people who think "ultra high performance all-season" is oxymoronic. However, if that's what you want, consider the appropriate Nokian tires. Even their high-performance summer tire will work in freezing temperatures (almost all summer tires turn into rocks below freezing) - and their "all-season" is better in snow than many snow tires. Hakka's also last a long time, even their snow tires can be used year-round. Not inexpensive, though.

Sizing - given the D90's you're proposing to use, go with the factory sizes 205/fr 225/rr. (I have 205/60x16 on 6" rims all around in the avatar, but that's because I wanted more ground clearance.)

Tom R. - agreed. Something like Pilot Alpins sounds to be perfect. I also changed my .sig back to a real name.

 

The GTO comes with a 18" wheel option. the tires are summer tires. There were a number of GTOs totalled when the weather dropped. bottom line, summer tires turn to hockey pucks once it drops to about 40.

When it comes to snow tires i defer to craig. I am sure it snows more up by you than by me. I also agree with the oxymoronic titles they are giving tires.

as for the width of the tire question. My GTO came from the factory with 245s all around and my snows are 225 all around. i can break the 245s away if i turn the TC off, so im sure i can do the same with the 225s. Contact patch. the two tires have the same size contact patch.

The difference is that the contact patch on the 245 is wider and shorter while the contact patch on the 225 is thinner and longer. in dry the wider patch helps in corners and grips more of the dry pavement. in snow you want the weight on a narrower strip with more tire grabbing front to back. my explanation sucks, but it is what i remember from an addco sway bar book i read some 25 years ago.
