HELP! new bfgoodrich KO2 rubbing

[pjwinstalls]

I always had 275 55 R20 bridgestone Dueler on my stock tahoe ltz. I decided i wanted a more aggressive tread. I bought 4 new BFGoodrich all terrain KO2 tires and now all 4 are rubbing on the plastic wheel wells. I dont understand why as they are the exact same size. TireRack says they are compatible and are blaming my suspension. My shop checked out my entire suspension and all is good. They say aggressive tread tires like that dont work on the tahoe. When towing my 5x8 cargo trailer it rubs with the slightest turn or bump in the road. I dont know what to do or what the real problem is. Any suggestions or advice would be greatly appreciated!

How about some photos? The stock sizes should not rub. Are you lowered at all?

What is the section and tread width of the two tires? Shouldn't really differ more than two tenths of an inch.

I am not lowered at all. The new KO2 tires are 11.1 section and 9.6 tread depth... the old tires are the same measurements. here are the pictures.....

Can't see the pics. Give this thread a bump after breakfast when the regulars on here start checking in.

Try now. Thank you

How about a side view of the truck? I ran KO2s but the stock size for 17" wheels and am fine. But the 20" wheel is wider and about 1/2" taller I think. Let's call in the cavalry, give me a few minutes to think who has these on their trucks...

I had to do some cutting under my front bumper. Unscrewed the wheel liner cut some of the plastic back with a circler saw lol, then used some deck screws to hold it back in place. I just traded her in or I would post some pictures. I never had rubbing in the rear tho, plus I had the rough country leveling kit On the front.

Update......

I just drove approx 40 miles alone in the truck with only my bike rack and 1 bike. No rubbing at all. When I had 6 people in the car the other day there was infrequent rubbing on some turns and bumps in road. When towing my 5x8 trailer containing camping supplies such as tents, bikes, coolers, etc... and 6 people in the truck I was rubbing constantly. Tirerack says it shouldnt be happening in any of these instances. FYI...i also installed a new compressor for the rear to rule that out.

Just made sure the photo album is public. Check again please. Thank you!

So probably nothing but a bit of added weight on old shocks. May be time for some new ones.

How many miles do you typically get out of the factory installed shocks? I have the autoride suspension as its an LTZ. I have rubbing on all 4 tires so what would you recommend I get installed? Thanks for the help!

Could it be age/miles then? The springs being worn? There is a minimum and maximum height spec from the ground to the top of the wheel well but I cannot remember where that information resides.

Mileage on shocks greatly differ on how theyre used id guess. As in if someone hauled a camper od say would wear faster then someone who just drives around town.

I had about 90k on mine before i changed they and man i wish in did It sooner. They wore out slowly so i never realized they were basically smoked.

I have bilstein 5100s (ones for a lift) now and theyre great its my 2nd tahoe with them. Many here also use them. Im pretty sure they have ones for non lifted tahoes also.
