Do you compensate for temperature when setting tire pressure

The most important thing about tire pressure is NOT to run them UNDER inflated. Over inflation will cause some issues (uneven wear, hard ride, etc) but the tire is unlike to fail. Under inflation will cause the tire to fail - often catastrophically. So, you MUST adjust your cold tire inflation pressure to match the outdoor temps. No, you don't have to get crazy chasing tire pressure. As long as you stay in within a few pounds you'll be fine.



Tire pressure is important. For safety and for performance. If you don't have a TPMS you have no clue what's going on with your tires. You are simply guessing and good luck with that!

Don't want to offend you, but I've driven 40 years and never had a tire failure, or even a flat.

Now go check your tire pressure.

Cheers!

Nope, don't need to. The CPSI aim is the same every morning regardless of whether you are driving in Florida or Alaska.

Once I have my aim for my tires and my weight that aim doesn't change unless I change something significantly with the coach.

Do I check PSI every morning before travel, nope. I only readjust after a few weeks of travel when going from daily warm climates to daily cold climates.

For example, on a 6000 mile trip from Florida to Anchorage, I adjusted the tire PSI once on the entire 6 week journey. That was done in Prince George BC. The reason they needed adjusting was that the average outside ambient temps were now a lot colder than they were back in Florida where I first started.

I have never seen so much to do on this forum regarding what to purchase for RV tires and checking PSI's of those tires.

This is NOT rocket science.

The most IMPORTANT bit of information regarding your tires you can go to the bank with is to NOT drive on an UNDER-INFLATED tire. If you do you WILL have a failure guaranteed. Or worse yet a steer tire BLOW-OUT which when happens people have lost their lives and/or ended up with thousands of dollars worth of damage to their coach.

Another thing that amazes me is that I continue to read various posts from people who don't use a TPMS in their coach. For those people I would strongly suggest purchasing a set of Tyron Bands for your steer tires. At least you will have a fighting chance with them when a failure or blow-out occurs.
