Tire pressure and steering column

Hi,

Just a couple of quick questions: I am running Goodyear Eagles 245/45R17 in front and 285/40R17 in the rear. Usually I inflate to 24 pounds in the front and 28 in the rear, but as the weather is getting colder and the pavement "harder," any suggestion as to what works best on the street (considering the broken up pavement common around New York City)?

Also, after 20 years,the paint is peeling (from the exhaust heat) u-joint in the steering column. Anything I need to do about this apart from painting it again.

Thanks.

Do you have your pressures reversed (front & rear) by chance? ERA recommends 28 front and 26 rear for a starting point. I generally run within a pound or so of that but I think you could even go to 26/24 with no issues. For the winter, if my car(s) is likely to be parked undriven for quite some time, I usually air the tires up to around 32 -34 for storage. If I think I'll be able to drive it every so often I usually leave them as is.

I think the steering shaft on newer cars is powder coated but it may be paint on earlier cars. If painted, I would use some gloss black brake caliper paint or engine block paint from Dupli-color - both of which are good for about 650 deg F. Of course if you are going through the effort to remove it for refinishing you could also have it powder coated. Not sure what the temp limits are for PC however - probably not as high as 650 F. As far as the u-joint, I don't think there are any serviceable parts in it - either it's tight and OK, or has play and is worn out.

Thanks.
As for tire pressure, I have generally run 24/28 for some 20 years and it has been fine, except in cold weather or bumpy roads, when they seem way too hard for street driving. Went 23/27 this weekend, and it softened things a little.
ERA 425 still running strong.

There is some high temp powder available in the market (up to 1200°F), but painting it new will be easier in this case. Powdercoating with regular powder will for sure due the job also...

The rubber in the tires will stiffen up a little and make for a stiffer ride. While lowering air pressure may provide for a softer ride, you need to keep an eye on the air pressure as colder weather tends to deplete air pressure. you might want to consider adjusting the shocks and making them less stiff during the colder months.
