What PSI do you run on your tires?

The Avid Ascends I purchased for my Honda Accord have turned out to be a terrible buy. I will be lucky to get 40-50k out of them when they were rated for 80k.

That reminds me of my Goodyear Assurance Fuel Maxes. They were absolute heaven on my Subaru, so I got them for my wife's minivan when she needed tires next. Those wore out, but the ones on my Subaru were still going strong.

I have using 50 psi for 240k miles/ 7 yrs. on my 2013 CMAX Hybrid on Michelin Energy Saver tires getting 87k miles on them.

40 mostly, it's a good compromise for my clunker.

Running 42 psi on all four tyres. Vehicle is an estate car (Toyota Avensis), Quatrac 5 all season tyres 205/55 R16 tires. Toyota recommends 40 psi front and 42 psi rear for fully loaded and speeds above 100 mph. At least anything else for that car/ tyre/ load results in uneven tire wear. Try to find the right pressure for your tire and setup. There is not such a thing like "one solution" fits all when it comes to tire pressure. In case of doubt take your vehicle manufacturers recommendation - and if only a single pressure is stated just add 0.5 bar. Otherwise take the fully loaded pressure.

From what I've read/experienced, tire wear seems to be best at sidewall max, and >70 PSI accelerates wear slightly on tires. Not all cars show a MPG improvement past 60 PSI, so unless yours does don't run them past 60 PSI.

Wow, what tires are you running 80 psi on your Insight? My understanding is that burst pressure is about 4x sidewall max. I was running low 50's on my Gen2 Prius. Snapped a rear spring at one point. I don't know if there was a connection. Currently mellowed down to low/mid 40's on my Gen3.

I read the label on the door frame and add 5 or 6 more PSI.
We have so many potholes, running 44 PSI is too hard on old folks.
If we're going on a long road trip, I like to use 40ish PSI, for the MPGs.

Someone created a thread saying they did the math and they calculated that even though they would wear out their tires faster, the improved fuel economy would more than compensate.

Apparently it wasn't this thread: I did the math..

In that thread Dave Lobi said that he made an air dam and grill block from lawn edging and if it increased his fuel economy by 0.5 MPG it would pay for itself over 20,000 miles if it cost $20.

I do 44 front and 40psi rear on a lowered V6 Camry. At 44 in the rear it seems a bit bouncy and twitchy on corners. I also don’t carry a spare tyre - just a can of spray goo so the rear is a bit lighter too. I have a larger rear anti roll bar which makes the car corner very flat...

How the car rides is definitely impacted by tyre pressure but a full or empty gas tank is noticeable too.

I'm about to replace my FuelMax's with something else. They're dying from age rather than treadwear, but now that they're old there is approximately zero traction. They're great when new but terrible as they age.

51 psi, sidewall max.
