Any websites you guys know of that I cna find correct pressure for my tires? If you know off hand for my tires they are continental extreme contact dw

 

driver side door jam has the proper PSI. so does the owner's manual.

 

The manual recommends 35 PSI front and 32 PSI rear and your tires' sidewall has the maximums, anything other than that is referred to as "driver's preference".

 

I am not running stock tires and rims? The tire for some reason does not have pressure on the tire sidewall

 

Since different tire sizes require different pressures, it's got to be on the tire somewhere, what about on the inward side of them? What size are the tires?

 

The pressure info on the tires is only the max, it doesn't tell you what you should be running and definitely don't run it.

Unless the tread patch on the different tire is significantly larger than OE, you should just stick with the OE pressure. Otherwise, you can either ask the tire manufacturer for their recommendation for your car, or you can grab pencil and paper and calculate it given the OE tread patch and pressure (have fun ). Personally, I'd just stick with the OE spec unless I changed to slicks.

 

just run 5-8psi less than what is recommended by the tire, most are like 41psi max, do the math.

 

Some of this info would seem to be common knowledge, but I thought a thread devoted to tire pressure would be a good place to put it:

This may sound crazy-
I have checked the air in aftermarket tires by:
On a dry day - taking some chalk and putting a line across the tread and drive a short distance. Then check the chalk line and you want to be able to see that it has evenly worn away. If the center has worn, then you have too much air in the tire and if the outter part of the line is worn, then you have too little air in the tire.
I hope this helps.
