I have had Nokian, Semperit, Dunlop, Cooper, and currently Gislaved winter tires on my 9-5s since 2001. My driving is mostly cold winter expressways, usually cleared of snow, sometimes slippery with black ice, and the ocassional snowy roads with up to 8 inches of white fluffy stuff.
With my driving needs I liked the Coopers best. These tires were never on my radar screen but I located a set of four Saab 15-inch alloy rims with new Cooper snows for only $400. The seller assembled the package for his wife's Chevy Malibu because it used the same wheel bolt pattern as Saab, but the Saab wheels wouldn't clear the Malibu's front calipers.
I drove the Coopers for three winters, or 24,000 miles total, and they still had two seasons of tread remaining.
The Nokians had the best grip by a wide margin but were down right scary at 75 MPH on clear winter roads due to their Q speed rating. The Semperits and Dunlops were both H rated and very stable at speed but not as grippy as the Nokians. The T-rated Coopers presented the best compromise for my needs.
Roger has a very good point. Narrow tires give extreme traction but very poor highway stability. The BMW that I tricked up for ice racing I ended up trailering it. This due to a combination of skinny 155 85 tires and no shock damping made it brilliant for traction on ice and downright dangerous driving on the road. I gotta loook up a picture I have of it somewhere; with no studs and the Hakka's so much weight transfer, it would lift the inside front wheel in a corner.
Just to clarify why I am running Gislaveds now rather than Coopers. I sold my 2000 9-5 lpt and bought an '08 9-5 Aero in early 2012. The 15-inch alloys will not fit the Aero so I went looking for 16-inch Saab rims and sold the smaller set to another 9-5 owner.
I found a set of 16-inch Saab rims shod with very slightly used Gislaved winter tires in the Spring of '12. The tires were being stored for the seller by a tire store and the seller wanted $400 for the set. I offered her $300 six months later and the Store owner convinced the seller to accept my offer since I had been the only interested party.
These Gislaveds are pretty darn good too, but when it comes time to replace them I am certain the Coopers will be far less expensive.
I need some help to determine what is going on with these rims. The rims are Voxx and came with summer tires mounted along with a OG 9-3, I recently purchased.
The problem: In the picture two lug nuts are seen. The left is 9-3 NG lug nut and one on right lug nuts are 12X1.5 on the OG...
