The Fred Posted October 11, 2006 Report Share Posted October 11, 2006 I don't have ABS on my '90 so I was wondering if it is alright to run the tires a little low on air when it's icy out... is it hard on the tires?

BodybyFisher Posted October 11, 2006 Report Share Posted October 11, 2006 I used to decrease the pressure in my tires to increase the contact patch but only for better traction in snow.. As far as I know, nothing other than STUDS helps with ice, not even ABS (that well). And I mean sheet ice, not patchy ICE. Loss of traction is loss of traction and abs can not improve that it will try but its a futile exercise. Obviously once you are out of the snow, its best to fill the tires to a normal level as you will wear them out, over heat them and get bad gas mileage from the increased rolling resistance.

PAUL T Posted October 11, 2006 Report Share Posted October 11, 2006 Running the tires underinflated will wear the outside edges out. As far as running them that way for better traction, you are causing less traction due to the center of the tire collapsing and creating a void that does not contact the road, just the outside edges are in contact with the road. Overinflating wears the center out and causes less traction. To get the most traction inflate the tires to the recommended pressure. This ensures even wear and full traction.

BodybyFisher Posted October 11, 2006 Report Share Posted October 11, 2006 Good Point Paul. Maybe I should clarify that I have only decreased pressure to get out of heavy snow to widen the tire, but you bring up a good point with the center of the tire not being pushed down to contact the roadway..

I used to do the same thing. Now if I want more traction I buy wider tires and keep them to the right pressure. Link to comment Share on other sites More sharing options...
Regis Posted October 11, 2006 Report Share Posted October 11, 2006 Good advice. One thing to keep in mind is that wider tires improve traction on dry surfaces and narrower tires improve traction in snow.
