Default Negative camber & Snow (Tires)

I just recently purchased some Dunlop Winter Sport 3d's from the tire rack fo r this winter season.

I also have a performance alignment with camber plates in front and bolts in the rear.

Specs are: Front 2.1 degrees negative camber
Rear 1.4 degrees negative camber
Toe is set at or closest to zero.

My question is do these negative camber settings affect how a tire performs in snow and ice conditions? Is it a good idea to go back to stock camber specs for the winter conditions? Is it dangerous to run this type of negative camber in the snow with snow tires...

I've run similar specs (-2.5 F, -1.8R) for three winters with Dunlop winter tires. Car handles great, and the tires only show slightly more wear on the inside edge (they're down to the "snow wear limit" bars right now).

so the tires still perform as they should with some addtional neg camber? i was mainly worried about the car being unstable in the snow with neg camber.

Fliz, which dunlops do you have and how do they perform in the snow....


I picked up 225 45 17 3d's this year.

I have the Wintersport M3 (I think that's what it is...it's the previous generation to the 3d).

They do great in the snow...not the best on smooth ice, but no studdless tire is. I did ice trials (autox on ice) with them the first two seasons, and I gave up a little to the Nokians, but not that much. Honestly, the only time I noticed a lack of grip that I attributed to my camber was initial turn in while ice racing.

When they were newer, I did notice significant tread squirm if the temp was above 50 degrees, but now that they've worn down I don't notice it at all.

negative 2.1 up front for winter should be fine, its actually not far off from stock. I have -2.6 front and -1.6 rear on Nokian WR G2. These are asymmetrical tread and I barely notice a performance drop.

Considering you run the Dunlops, you will have less of a problem then me.

Generally, more negative camber will affect snow performance because you will not be utilizing the full width of the tread and also cornering, speeds will be much lower compared to dry conditions thus less performance and additional inner tire wear.

On the bright side, since your camber is not that aggressive, the difference is negligable. Unless you get alignment for free, I say screw it and keep your settings as is all year round.

I have no track experience at all so I can't comment on that type of performance. As far as street, you will be fine.
