what pressure do I pump the 'warm?' tires up to?

And as posted on another thread, best is to get proper TPMS sensors. Externals are the easiest way to go. I got this set a few days ago (it was $10 cheaper) and working good so far.

Why would you buy a air pump? There’s one with the car already. See p. 531-532 of owners manual.

 

I did not know that. Thanks. I had mine from the previous car, but now I can give it to someone else.

 

As I understand it you should follow what is on the door jamb

 

I have a TPMS and temperature has been in the 100s here in TX. My tire pressures read 34psi cold and I've seen them get as high as 39psi at 109F temp at the tire. I highly recommend a TPMS as it will put your mind at ease.

 

So glad I checked this thread. Just measured my tires (car is about a month old) and the PSI was50 in each tire. I deflated them to about 42 and probably need to deflate some more. The car is sitting in the garage so I assume that I should get it down to the "cold" reading of 36. I used my bicycle pump to check the psi since I had nothing else. I'm going to get one of the gauges referenced on this site.

 

I was concerned that the tire leak plugging material in the pump that came with the Clarity could get into the tires during normal tire pressure adjustments. I ended up buying an inexpensive air only pump for that purpose.

 

I use Rand McNally’s TPMS. My only complaint is the batteries is ships with don’t last very long with a ton of driving (18k) so I’ve had to replace the batteries. You should plan ahead as they are not cheap if you buy them locally costing more than the currently deeply discounted price of the kits.

The nice thing about this is you throw the receiver in the glovebox or arm rest and ignore it until it needs to be recharges (every 1-2 month) then you just plug it in to a usb in the car to charge it back up. At some point I’ll likely add an accessory plug in the armrest so I can leave it plugged in.

I’ve been using the Honda included pumps since at least my 2013 Civic hybrid. I’ve used the pumps included with my wife’s Kia Optima Hybrid and Niro as well as in my Clarity to top up the tires. Keep in mind if you have nitrogen fill you are diluting it and adding a little moisture to the mix in the tire. I am, however, not 100% sold on nitrogen fills.
