Tire Pressure ???

All shouldn't be the same and as said weigh and set according to toyos recommendations. There is an exception in the tag that several knowledgeable folks ( for what that's worth ) told me. My tag weight called for 80 lbs and I run 90. It was explained that the tag has s lot of scrub force on the sides. I had a les Schwab tire store refuse to put less in. I asked around and have kept them higher with no ride difference. As a truck driver We ran high pressures all around because of varying weights. I still run higher pressures on both rear ( 90 tag 100 drive ) as my handling isn't any different and I prefer the extra margin. Chart called for 80 tag 85 drive
What's your handling like with the higher pressures ?
