Re: winter tires for Caddy STS [markcincinnati] by mnjasper

In the end, thanks for everyone's advice. The Blizzak LM-22 is the only tire I could find that comes in the standard sizes that came with the car. Lots come in one or the other, but finding four tires of the same model in the different sizes was a problem. When I put the car model in Tirerack, I did not find any. But when I seperately put in the sizes, I came to the Blizzak LM-22s. That is the decision I made. I didn't want to buy two of one model tire and two of another model tire because the winter tires all say to not mix and match.
 
I have a question, though. What do you mean by "minus zero the 235s"? I could find no one, including the Cadillac dealer, that could tell me if it would be bad for my all-wheel drive to put four of the same size all around.

As a general rule it is best to "Minus-One" (i.e. down one inch in wheel diameter) and go with the same width or slightly narrower tire than what is mounted on the front from the factory, hence the recommendation to use the 235 section width tires. By buying winter tires that fit your factory wheels you are significantly compromising your cars' winter capabilities.
 
The best bet (and over the course of two or three years the least expensive) would have been to follow the TireRack recommendation of 235/55 R17 tires. Is it too late to change your order?
 
Best Regards,
Shipo

Minus or plus sizing -- minus zero, minus one, minus two -- simply means keeing the size of the tire that the "computer thinks" is on the car the same.
 
For instance, if your car comes with 225 x 55 x 17 tires, you can PLUS ZERO size them to 245 x 50 x 17, gaining a wider tread, a lower profile and retaining the 17" wheels. The distance the tire travels per revolution is "very close" to the factory set up, so everything continues to function normally.
 
Plus One in this case could be done and you could go to a 245 x 45 x 18" tire/wheel combo and again potentially gain improvements from this change. Appropriate tire ratings, capabilities, compounds and design, too, will effect the outcome of such a Plus sizing. Some folks plus size ONLY for appearance sake, but often a performance boost (handling) can be gained too.
 
Minus sizing -- is usually done for winter driving.
 
You could minus zero or one your tires/wheels on your Cadillac. If you minus zero your wheel size will not change, your tread width will narrow and your aspect ratio will increase.
 
If you minus one size, your wheel size will decrease by one inch.
 
Why your dealer wasn't conversant about this is another matter.
 
Tirerack has help on their site on this subject.
 
I have often plus zero'd my tires on my cars to gain a bit of improvement in "turn in." Such an approach is not expensive since no new wheels are required.

"The GS and M still get hammered by the 5 and E though."
 
Infiniti car sales in the U.S. were down 12.4% through Sept, compared to first nine months of 2005. The only model with sales higher in 2006 is the M. However, third quarter (July+August+September) 2006 sales of the M ( 2,293+ 2120+1933=6346) were down 22% from third quarter 2005 ( 2,755+2623+2351=7729).
 
Lexus passenger car sales in the U.S. were up 22.2% compared to the first nine months of 2005 (131,595 versus 107,246). Most of the increase, however, was the IS 250/350: (41,666 versus 4,261) an increase of 873.6%. GS 350 was down to 18,219 from 20,332 (a decrease of 10.8%). And the GS 430/450h was also down to 3,026 from 4,430 (a decrease of 32%).
 
At the end of September, Mercedes-Benz USA reported its highest September on record with sales of 19,873 new vehicles, an increase of 13.2 percent over last September. This brought MBUSA's year-to-date sales to 177,001, a 13.3 percent increase over the same period in 2005. Sales volume September was led by the C-Class with 4,238 units and the E-Class with 4,112 units. Nonetheless, this represented a 9.5% decrease (September to September comparison) for the E-class, which has been down 6.3 compared to first nine months of 2005. And, during the third quarter of 2006, the E-Class sales have been down 16.7% as compared with third quarter 2005 (15,061 versus 12,546).
 
People appear to be buying fewer LPS category cars as the year unfolds.

Interesting stuff.
 
I analyze data for a living. It's nice to not have to gather & parse it myself.
 
It appears that the great unwashed care not a whit for the abysmal Mercedes electric/electronic reliability stories. Or, maybe they've gotten better.
 
Thanks

While 5-series sales were up for the first three-quarters from 36,261 in 2005 to 38,944 in 2006, nonetheless in the recent third quarter, even 5-Series sales were down 14% to 11,109 from 12,877 in the third quarter of 2005.

Just about all of Infiniti's sales come from G, M, FX. The '06 G is EOL, and the FX is starting to showing its age. Infiniti should get a healthy boost for the '07 G35. The additional showroom traffic may also boost M sales.
 
The IS is doing pretty well, it will be interesting to see if it can maintain these kinds of sales numbers and avoid the curse that has killed all of Lexus' previous performance cars after a few years on the market. It looks like the GS may be falling into the same trap for the 3rd time.

New engines in 5 Series by erickpl

How do you think the twinturbo of the 335i will fare in the 535i? In talking to my dealer, he was mentioning Spring for this option. I dunno how true that is, but the idea of a 535i appeals to me. It has more oomph than the 530, but without having to jump up in price to the 550.

I absolutely think that a "lightly lifted" (from a sheet metal perspective) 535i 6-Speed Manual with the SP will be too good to pass up. I also suspect that others are thinking the same thing which, to me at least, explains the recent drop off in E60 sales. After all, why buy/lease a very competent 2007 530i now when as soon as next spring an ultra competent 535i can be had?

Audi sales by sfcharlie

Audi of America sold 8,004 vehicles in September, a 1.9 percent increase compared to the same period a year ago. Audi sales are up 4.9 percent for the year.
 
Audi was one of the luxury brands to improve its sales during the third quarter totaling 22,124 vehicles sold, one of the strongest quarters in the brand's U.S. history, with new markets on the rise in metropolitan markets such as Miami, Los Angeles, Atlanta, and Dallas, where Audi hadn't sold much before. The brand appears to be, in general, slowly opening new markets outside the snowbelt, where most of its sales have traditionally been made.
 
The A6 sold the same number (13,000) so far this year as it did in 2005, but, as with the other LPS cars, was down 18% in the third quarter, compared to third quarter 2005.
