I lowerd mine a little when it snowed pretty heavaly so that i wouldent get stuck. I put mine to 44 from 54 because i was loseing traction. The only reason though was the snow but when it rains i just increase my folowing distances by 2-3 secounds on the interstate and a little less in the city. I just know that i have to be alot more carful when it comes to the weather wit the higher pressure tire so i drive like it. Also its not the safest thing in the world to do but most kids in my age group (17-19 ish) drive freakin crazy so this is my rush knowing that a tire could exsplode or lose all traction.
Good info! My pressure is set at the factory suggested 23 PSI front and back.
I'm going to bump it up to the sidewall pressure to see what happens.
My first concern is the ride. Even at 23 PSI my Sidekick rides VERY VERY hard. Almost to the point of being uncomfortable. Can only imagine the sounds my high mileage suspension is going to make and the handling with a truck that is only 1900 pounds when I add more air.
My wife and I took a trip up to NH last weekend -- slush, freezing rain, salt and sand. Tire pressures were at 38/40 and everything was fine. The only time I lost traction momentarily was when making a sharp left turn across the piles into a driveway to turn around.
Road surface quality helps a lot. MA roads are generally the worst in the region, but I'm fortunate because most of my newer hypermiling route to work has recently been repaved. On my former route, the car would go airborne on frost heaves, so high (or even normal) pressure in rain was very dicey.
I have had no problems with traction on wet roads despite maintaining my Michelin Harmony 175/70/13 tires at 60psi and I take the corners pretty fast. Now that my tire's tread is getting low after 60,000 miles, I have to take it easy when the water is lying thick on the pavement, but they are perfectly fine on normal wet roads.
Good point about the deer because a few months ago that happend. I ended up hiting it but it wasent because of loss of traction it was just he jumped out from a froresty aera on the side of the road maybe 30 feet in front of so i hit the breaks hard and it didnt really skid or lose any traction. I was doing 60 without loss so thats pretty good.
