Tires making more noise
I took my 03 cab infor an minor service a month ago and when I got it back, immediately notices more tire noise. Sort of a drone at 40 mph coming from the rear where I have Perelli P zero's with 50% tread left. I asked the service dept whether the left and right rear tires could have been switched causing the increased noise. He said no, that they are directional and were not removed. I asked him about checking the breakpad wear for the service and he said that the wheels were not removed. Does this make any sense?
Thanks

My '04 40th anniversary came with P Zeros. They were always loud and became much louder as they aged (my subjective assessment). I don't remember a step change in loudness, but they certainly were annoying. "Drone" is a good description. Rears lasted 13k miles, fronts lasted 25k. I went through two sets of rears and one set of fronts and, at 25k miles, replaced them with Michelin PS2s. The Michelins are much quieter, ride better, and wear better. Just my $0.02.

Not sure how the service could have increased the noise unless they bumped the alignment out of spec. But if they did that, it would normally show up in handling.
That said, as the tires age on my 996, they get progressively louder. The coarser the surface on the pavement, the louder they are. I drove a few hundred mile trip last Tuesday on coarse highways. I actually wore ear plugs for the return trip, the noise was so loud. I'd hit a smooth stretch and it would quiet down -- then loud again with the coarse pavement surface. Not so much a drone as a muffled roar. I have Michelin PS2's on mine. When new -- pliant and quiet. Now with thinner tread -- much more noisy.
It is possible that after your service, you were more attentive to the car's movement, noise, etc., and simply started noticing it more than you had in the past.
Having an alignment shop check your tires, etc., makes sense if you think there's a safety issue or you think you're seeing unusual wear on one or more tires.

You should be able to tell if the rims are reversed just by looking at the tires - there is a block of text that reads either "direction" or "rotation" and is followed by an arrow. If the arrow is pointing counter-clock on right or clockwise on the left - they're swapped.
As previously said, my tires (Contisport 2) were very loud and bouncy at the end of their lives. I replaced with PZeros, and so far have been really impressed.
Another thought - could they have knocked off a balancing weight somehow??

my pzeros turned into sawblades as they wore down to the indicators particularly at 40-45mph. they are known for it. you probably just didn't notice it before as it was gradual, but once you hear it, it can never be ignored again! no more pzeros for me!

Wheels do not need to be removed for a service. You can look between the spokes to check brake pad thickness. Chances are you are just looking for a problem or that when they lifted the vehicle it triggered a failing wheel bearing. I have seens wheel bearing on their last leg fail once weight is taken off and put back on. I am willing to bet it's just the tires but that is just another idea.
