Can you rephrase this? by tcalof

"In the snow, you are required to run a higher pressure due to the fact that the tire present friction in snow dramatically if low."
 
Sseiboi:
What are you trying to say here? That the higher the tire pressure, the lower the friction and less traction?
Or the higher the tire pressure the higher the friction on the smaller footprint and the better the traction?

What im saying is in the snow, you want to run higher psi because your tire becomes more round when it touches down instead of sitting flat. Plus, it allows the tread blocks to easily sipher snow out of the grooves faster and more eficiently with less friction. Lower psi will sit more flat and snow will wrap itself on the side wall of the tire instead of the tread.
 
Imagine the tire as a balloon. When you first blow it up, it looks flat and a little mishapen. as you add more air, it becomes rounder and solid. Same concept.

Cruise Control by tsjay

I sure wish my little Cobalt had cruise control, but it was the last one on the lot at the time, and I decided to take it, even though it didn't have this feature. I didn't realize how much I would miss it.
 
I have checked a couple places that install cruise, and the prices were $395 at one place and $425 at another. Is that the going rate? I didn't realize it would cost so much. I was thinking maybe $250 to $300.
 
Any suggestions?

Have you checked with a dealer to see what installing the parts would cost? I don't know how the cruise is turned on / off in a Cobalt. But I would suspect the wiring is all in place and the computer chips are there just waiting to be booted up with cruise in place to turn on the cruise functions.
 
It would be worth asking for me. It might be worth getting a factory service manual form Helminc.com if you're good at reading wiring. Then you could get parts from a recycling yard from a donor Cobalt...

Thanks, imidazol97, but I am NOT a do-it-yourself kind of guy. I mess things up when I try that.
 
I have checked with the dealer, and they referred me to one of those places that I menitoned in my first post.

Those prices are fair, especially if they are giving your steering wheel or stalk controls. A simpler installation glues a push button panel to your dash which activates the cruise via a low powered rf signal.
 
Rostra is a brand that seems to make a lot of these.

Thanks, micweb. I was wondering if those prices were in line.
 
So, I guess I have to decide just how badly I really want cruise. Right now, I don't think I want it $400 worth, but I could change my mind.
 
I would want it to be just like "factory," if I got it.

The current issue has an article on cars their readers won't purchase again. 46% of them won't purchase another Cobalt sedan. I can't figure out what is wrong with the Cobalt. I've rented a lot of compacts and find that most of them are pretty much alike. Some have fancier interiors but I have had nothing but good luck with my 09 LT1 coupe. I understand that the 05's and 06's had small problems -squeaks, small warranty things and most of the bugs are gone now. Of course everybody loves their Japanese cars -typical CR readership.

Whenever I bring my '06 Cobalt LT Sedan to the dealer for an oil change they always set my tires to 35psi even though the doorjam says they should be 30psi.
Same thing happens at Discount Tire. I went for a rotation and they set the tires to 35psi and said it was better at that level.
I'm confused-what psi do you guys keep your 'Balt at?
 
Also my car is riding horribly. It almost feels like my shocks/struts have no fluid in them, its that rough over bumps. Also, now my car doesnt even handle properly-it feels tippy around turns where it used to at least handle well (kinda made up for the rough ride!). Also, on the Freeway here in SD the car has terrible back and forth action on the grooved freeways (brand new Michelins did not help at all).
I am very dissapointed in the way the car is riding. Its really the only thing that bothers me about the car, but, hey, thats a pretty big issue.

Get a quality tire gauge of our own. Set your tires to a pressure you want when stone cold in your driveway after sitting outside all night e.g. Remember the ambient temperature changes the pressure about 1 pound per 10 degrees (F) of temperature rise of drop.
 
I often run a couple or three pounds above the recommended. I have Michelin tires on my cars but they're not Cobalt.
 
As for being sensitive to wiggle on grooved roads, that's most likely a function of the alignment. It should be set to perfect--especially for the rear. This is one time it might be worth a dealer visit for the alignment over the local tire store, depending on the experience and attitude of the guy on the alignment rack.
