I've got 15,000 miles on the OEM Potenza RE050A tires on my 2018 GS350 F-sport RWD. All four have excessive wear on the outside edges. Anyone else have this problem? Should I drive slower in the twisties? Try to get the alignment guys to dial in more negative camber?

If not alignment check tire inflation. Usually tires that are wearing excessively on the outsides are under inflated. That would be both outsides being both outside edges of tire. If only on one side then sounds like the alignment.

Get an alignment when you replace your tires.

If it’s only on the outside edge of each tire, you’re looking at an alignment. If the wear is on the edges or shoulders of each tire, your tire is under-inflated.

Thanks guys. I got the alignment and the toe-in was out (in?) on three of the tires. I had a nail in one of the rears so now I've got Michelin Pilot Sport P4S tires on the rear. Hopefully they'll wear evenly and the fronts won't lose any more on the outside edges.

Did you get the settings before and after your alignment? Post them up, let's see how bad it was. And what do you mean on 3 of the tires? I've never heard of a 3-wheel alignment...
