On my 02 Avion I had "E" 80psi GY Wranglers the rims were 80psi rated. Based on my actual weight my tires were maxed out. I changed to GY "G" tires and the chart said 80psi based on my weight so I ran 85 per GY Tech support. I ran those tires for 4 years and thousands of miles with perfectly even tread wear. The 80 psi rim rating has a safety factor, they don't magically explode a few psi higher.
