My 2022 RT came with the 5GT's and I've put 5500 miles on them. My previous RT was a 2005 that I put 182,515 miles on and have been running Dunlop Roadsmart 3's. I like how the 5GT's handle and perform....BUT....the noise from the tires. Strait up its a constant harmonic noise that goes away with a slight lean to the right or left, so straight line long distance droning down the road is....lts just, say, not what I'm accustomed to.
Hmmm, sounds like a warranty issue. 😏
I get that tires are a wear/consumable for a motorcycle, but on a new 2200RT for which you spent beaucoop $$$$ on, the tires ought to ride smooth as silk and quiet enough so that only noise you hear is the soft heartbeat & purring of your advanced Boxer engine. 🤣
On the other hand, if you're riding on the tires polyester cords instead of rubber because you've been going hard at it in the twisties for 6000 miles, well, then ya got another problem.

A little more seriously, when this has occurred with my cars or trucks, it's invariably been due to (a) excessive/misshaped wear due to poor balancing and/or (b) mechanical problems leading to the same thing (e.g. front end, shocks, bearings, etc.). To be honest, even though I've taken early PR's to over 10K miles, I like LOTS of rubber underneath any vehicle my life depends on, that has half the wheel redundancy of a car (i.e. only two wheels). If you have reached 6K miles on your PR5's and are hearing noise, buy a new set of rubber, and feel happy to do it, IMHO. Better rubber is better handling under more varying conditions, and also better control over the unexpected. I'd still consider taking it by the dealer, and asking them if it's normal for an RT to wear tires unevenly, or if there isn't a latent issue developing, i.e. bearings, axle alignment, etc.
I won't insert a link here, but Michelin has this little diagram about their PR5's, regarding hydroplaning prevention. Notice the difference in the tread under "used for 3502 mile". While they are touting the superior handling and braking performance, their tires like all others, DO WEAR, and that leaves you with less rubber between you and the very hard pavement.
I don't want to sound insulting, honestly, this isn't directed at you personally, but as a general comment. There's a running joke about
"the only thing cheap about a BMW is the rider in the saddle". I might feel differently if I were putting 25K to 50K miles on a Beemer a year (e.g. slab commuting, which I've actually and unfortunately, done quite a bit of), and mounting new tires every other month. However, it amazes me that owners will shell out $25K+ for a pretty new BMW RT, only to hesitate mounting a new set of $200 to $350 tires to give the bike it's best performance, and the owners, best chance at life in a critical road situation.
/end rant (Ok, OK, I apologized in advance .... just sayin' 😬)
