: Tend Your Tires

Yep! It's that time again.

For every 10 degrees (5 for you 'C' folks) the temperature drops, you lose 1 psi. If you're fussy like me, it's time to 'play with' tire pressures, again. Those of you not enjoying the recent drop in temperature, your time may be coming soon... Boo!

I like to run 28 in back and 29 in front (Yeah, they wear a bit but it sure feels good!) YMMV

End of PSA.

Coincidentally, I just checked mine since I got the tires swapped between my Eldo and Deville before I sold it. Don't want the new people getting them nice Michelins I just put on that car, that'd just be too nice of me. I'm sure they are happy with those old cracked and worn ones :)

Filled exactly at the pressures on the door sticker.

Or you can fill them with nitrogen and not worry about temp swings

Nitrogen expands and contracts with temperature just like air (of which it is 80%). Race teams use N because it is dry and eliminates the effect of water vapor in pressure gain with temperature. If you discount the value of N keeping your TPMS at optimum (maybe so) it is a just waste of effort and money in a road car and its tires.

Check 'em. Pay $20 for a N 'top off' if it pleases you. But your tires are your connection with the road. Care for them... and yourself.
