Hello Gracious Lady, Have a great day.

Thanks, Pat, and the same to you!!

Look in your owners manual for proper tire pressure, there may also be a a sticker on ond of the doors/door jambs of possibly inside the gas door that will tell you what amount to put in them, how often you check them does depend on temperature, the colder it is the more often you need to check them but as an average, check them once a week just incase.

*ond* should read "one"

Thanks, Lit. Unfortunately the owners' manual was lifted somewhere along the line when I took the car in for service. It has disappeared from my glove compartment.

Check the doors/jambs and gas door for a sticker that may contain the info. May also be on a sticker in the glove box.

Thanks, I will do that!!

Tires are manufactured to your specific location so weather has already been factored in. Use the average of the variance stamped on the side of your tire. The most important factor is to keep all tires equal in pressure and do not go over or under that recommendation. Check tire pressures after your vehicle has been sitting, not after driving it.

Even if you check your pressure at 5 below and the next week it's 40 outside while you see a variance in pressure it should still fall within the allowable range. Yes there is a flux but not that much of one.

Thanks a lot Penny. I appreciate your advice!

What people are telling you is valid but for different conditions. In Nascar those tires get super heated and the expansion factor is huge but I assume you don't drive 200 mph, your tires have steel bands in them, etc, etc, etc.

Most tires have both max and min pressures stamped on them but you can google it out if it doesn't. If it is below zero when you check them just fill them to the min but anywhere in the average range has already been figured out by the manufacturer. Tires in FL are not the same as tires in ME, most people don't know that.

No, I did not know that! It is the first I am ever hearing it!

Both the rubber compounds and the thread pattern are specifically designed for the climate they get used in. All season does not mean all geography. Northern tires are softer, to get the grip required and to sustain the cold temperatures, southern tires deal with more rain and extreme heat, so harder composites and tread patterns designed to dispel water. A northern tire won't last but a couple of months in FL, a FL tire won't get any traction in the north and wears out quickly because of it. So your tire is designed specifically for your climate and meets those standards.

Read the recommendations on the side wall of the tire. Every tire size is different. Also different tire designs call for different pressure levels. But it is usually the same regardless of outside temperatures. The air pressure contracts in low temperatures, and expands in warmer temperatures.

That is the maximum the tire can hold, if you inflate them to that amount, you will create a harsh ride and ruin the tire prematurely, follow manufacturer specs for each and every vehicle as they WILL vary vehicle to vehicle.

Thanks Maddad. I know my tires get low so fast in the cold temps. I have been given different advice by different garages, and was just curious, and I want to do it right. Unfortunately my owner's manual disappeared from my glove compartment - lifted by someone when I took the car in for service, or from a valet ...

it's on the door jamb. usually 32 to 35

Thanks Rick!

It's on the side of your tires

Thanks Roscoe!

Thanks LS

google it

Thanks, Soviet. By the way, I am wishing all the best for your Dad! (saw your other question - try not to worry and keep us posted!!)

I thought all Illinois(D) residents knew how to keep tires inflated.

ROFL I got it, wonder who else will, "yes they can"

:o)

LOL sorry to disappoint! (don't meet your criteria)

Up here in Alaska, we keep each tire different during the winter months because of the streets and ice.

Thanks a lot, Pat. I know my front tire pressure is different from my back tires.
