need new tires
I'm in need of new tires, leaning towards goodyear endurance, but spendy. Also considered carlisle and maxxis. Just wondering why I never hear anyone or read any article about firestone st tires. Any...

Just checked Discount Tire, and realized that the Endurance in 225 15" are only available in an E rating. My KZ is placarded for D tires, which gives me a tire load capacity only 360 lbs below my GVW. So, that brings up the question of do I stick with a D rated tire or spend more and go to an E rated tire, which would give me 1,332 lbs OVER my GVW tire capacity (at full psi)? Do I spend $120 more (plus tax) on the Endurance and =deflate= to 65 psi to get the same load rating as a D tire or just buy a D tire, which, IMO is plenty for my fairly light FW? FWIW, I've had good luck with 2 different sets of Carlisles, so that would be my D rated choice.

According to the GY chart, 65 gives me the same as the D.

That is correct. That's why I said what I did. BUT... if you are already weighing enough to require 65psi then per GY Tech you should add 5 and run 70psi when upping load range.
I went from GY "E" to "G" and was already requiring 80psi so I ran the "G" tires at 85. After many thousands of miles the tires ever wearing perfectly.
My GVW is 10,500 lbs; my total tire capacity is only 300 lbs less than that. I =know= there's =way= more than 300 lbs on the pin, so why go to an E tire, then "de-rate" it by lowering the pressure? At 70 psi, I'd have more tire capacity than the GVW of my FW.
