(Michelin Tires will take 500 to 1,000 miles to break in! It's the only thing that I don't like about Michelin Tires. I've had to endure this many times in my 44-1/4 years driving over the road on Michelin Tires. The Michelin Tires on my RV are aired up to 100 lbs. all around.)
The age old "what do I inflate my tires at...my rig is not overloaded so do I need to go on (find) a scale?
You put yours at 100 psi front and back, why?
Some say closer to max PSI (on front tires) offers a better ride?
I have 235/80R 22.5G
