HELP! new bfgoodrich KO2 rubbing

[qcon]

I just mounted K02 on my stock wheels and suspension with no rubbing issues. Size is 275/55/20.

Have you towed anything yet? Do you have any pictures you can post? Would like to see the clearance

I guess I'm not clear here.
You have over sized tires on a stock setup, and are concerned that they rub?
Perhaps the question is why were the Bridgestones undersized?

I have no problem with a trailer and stock KO2,
don't think I would want to try larger size though.

No Mike, he is running stock sized tires both times on his original 20" wheels. The Bridgestones are physically slightly smaller than the KO2s. I'm thinking his suspension is worn and possibly overloading the rig while towing. Are those 265-70-17 or 265-60-17 KO2s on yours? Tahoe looks great, save for that missing center cap! hehehe

Philip, is it possible you were overloaded in the cab? Check the tire load and information sticker inside your door or door jamb, it will list the maximum capacity and your axle ratings. If your passengers are on the heftier side, like me!, you'll quickly run up against the various limits, especially when towing.

I made a towing calculator on excel but have been slow in getting it peer reviewed to make sure its as accurate as possible.

I'm lowered 2" in the rear and 1" up front with NO rubbing.

Late response, but..
The post said 275, isn't stock 265?

I have 265-70-17. My chart doesn't show that there are 265-60-17 KO2s.

(Picture of me picking up my trailer after ordering it and waiting 10 weeks for the build. Knew I would be taking "baby pictures", but forgot about the missing cap until I took the picture. It's been replaced, and was tricky to find too, kept running in to the shiny version.

His stock tires are 275-55-20, which mathematically speaking, are .3 inches taller than our 265-70-17. 31.91 vs. 31.61 and are obviously at least 10 mm wider.
