Tire Pressure monitoring
#11
I have run several of these things on motorhomes...they are not super pinpoint accurate on what your tire pressure is...don't freak if your pressure is 2-3 lbs different than your air gauge ...their main purpose is to give you warning that you have a tire losing air...so you can get to a safe place before you have a flat ...most blowouts are caused because you ran over something...the tire started losing air...and then overheated from low air pressure.

It think it being way over analyzed here. About as silly as filling your gas tank during the heat of the day or after it cools off in the evening. Or the recently debated "How much regular unleaded is in the hose when I choose super unleaded". CTP's
Ratings on tires are for cold psi. Expansion is figured in there already.

For years all I did was check tire pressure before a ride. Now that I have a Heritage checking the back tire for me is a bear. I bought the FOBO tire monitoring system to help me with checking the pressure before the ride. Today was the first day I have had it working on a ride and it is almost too much information.
When I started out the front tire was 1.2 pounds under the 36 and the rear was 1.4 pounds under the 40. So I get to my destination, just a short 30 mile ride and check the pressures again. This time the front is 3.8 pounds over and the rear is 7.2 pounds over.
Talking to a guy during lunch he said he usually inflates his tires to 5 under before the ride to allow for heat. I am not sure I am ready to do that but the evidence tells me maybe it is a good idea.
What do you all think? Keep the pressure to recommended pressures or go 5 under?

I always checked the tire pressure before a ride when the pressure was cold or not ridden on. I just never knew how many pounds the tire gained on a ride and it surprised me. Then it got me to thinking is this what leads to premature wear of the tires.
In reference to the tire gauges, How do we know their accuracy to begin with and whether or not tires are being inflated correctly? Just thoughts and maybe overthinking some. I do know I had a heck of a time using my gauge to inflate the tires to HD specs, then reading the monitoring fobs, trying to match them up.

no, you're going to get increased wear if you do like your buddy and run them under inflated to allow for expansion. if you go by the tire mfg suggestions, they have already taken into consideration the expansion of air in their psi recommendations. (your buddy's name wouldn't be cobraracer by any chance would it )

i think what he is saying is that when you start getting into the 'point x' area of psi, then you're getting in too deep. are you really going to notice less than a pound of pressure?

I did notice one thing when i checked the tires using the software this morning. The front fob was 75 degrees and the rear 77 degrees in the same shed. Maybe these monitors just need a learning curve to use I am not sure.

No Ha Ha The guy is a local here. He also says he gets 20K out of his back tire going 5 under. Me I wouldn't know when the pressure is .1 over or .8 under, it is that software program that tells me that. I am just going to keep using my HD gauge and let the software report what it can.

mine don't. i have to 'teach' the computer the new locations of the sensors if i rotate the wheels at the house. if i have it done with an oil change, the dealer has a little 'magic' box that he goes around to each tire with.
