I put a 2" lift and 33" Kelly tsr tires on my 2011 f150 screw. And everything was cool. But now the interior is making a lot of noises. From the front two doors and the dash its rattling bad as I drive now. The dealership is really no help and have made it worse. They say the tires are making it noisy. What say you? I know many have lifted trucks and don't have these issues.

 

The tires cause more vibration hence why they hum and that'll make things rattle more.

 

Can't believe its that much of a difference. Thought 35s would be bad. Not 33s.

 

The type of tire is more important than the size of them. From what I recall, those Kelly's are pretty aggressive, and the tread on them is pretty close to a mud tire. So I agree that they could definitely be the issue behind the noises. It is a little unusual that it occurred so quickly. I know that some trucks running big lifts and Toyo mud terrains can develop some squeaks here and there over time, but your case is a little unusual

 

What he said^. It's not the size, it's the tread.
