275/55/20 Tire help!!

[Mitch2013]

Hello All,

I just took off my 275/55/20 Goodyear SRAs off and had 275/55/20 Cooper AT3's put on. Stock Rims. Same Size stock tires. When I back up the passenger side front tire rubs on the mudflap. Any idea why this problem would happen all of a sudden? I have contacted Cooper and they suggested an Alignment. I really dont feel the need to pay for an alignment as the vehicle goes straight down the road and the old SRA tires had normal even wear. Any other thoughts?

Vehicle: 2013 Tahoe LTZ bone stock

It could be the outer wall of the AT3's are more aggressive and thicker that tha SRA's. I have the same issue when I installed the AT3's on my truck as well. It's also when I back up and it's on the passenger side mudflap. LOL. Hopefully as the tires wear out, the issue will go away. But I don't see this to be such a real problem.
