Wondering what others think of this. It is said that max psi, 42 front and back per manual, give the most longevity. It's also noticed tires wear out the most in the middle, hence chicken strips. Would it not make sense to reduce pressure somewhat so more of the tire contacts the road, distributing wear? Not so much it's squishy.

Unless you are maxing out the weight on either axle and are not running up to max speeds often you can move pressures around some, most find a pressure they perfer, if you set pressures to 42 when its 70 degress your pressure will change as that ambient air (cold) pressure changes from 65 to 70 to 80, when i set at 42 for max load in Phoenix which i am right now that will be 41 or 40 when i get in cooler places in the morning when i check air pressures. Some different presures and temps below

If you're talking about the Cobra Chrome's then at 190 lbs I like 40 psi on the rear and 37-38 on the front. That feels best for me but if you vary the pressure you should find the sweet spot rather quickly. If you change up the tire manufacturer then you have to do the same thing all over. All tires are not created equal.:thumbsup:

I was referring to weight on tire it says something like max weight 880 at 42 psi cold, but youre right just didl it in for you unless you meet the weights listed on tire than it should be set accordingly, unless youre maxed out traveing or trailering you wont meet those weight numbers stamped on tire.

I run the same pressure. Front at 37 to 38 seems to smooth things out a lot.

rocket 3 GT,
I'm at 38 and 38 and very happy on Avon Cobra.
I also run 38/38 in my 2020 GT.. Tried 42 all the way around but it seemed harsh on small bumps. Seems a little lower pressure would give
some additional contact patch as well. Below 38, the front end seems a little heavy at very slow speed turning.

On my BMW K1600 B I noticed the tire pressure goes up roughly 2 psi after a few miles, so I run 40 psi (static) front and rear on the R3 so my actual operating pressure should be really close to 42psi front and rear. I have noticed through the years and many many sets of tires that I get a more even wear and more longevity running them at their recommended max psi which in most cases is 42psi
