I have the same wheels and feel your pain. The standard tires for those wheels are the sizes listed in the screenshot from tire rack for the Toyo Proxes R888R series tires
While most owners fitted 335 profile tires, the 315 profile is not notably narrower when installed
pirelli P-zero series has several models, and if you mix and match between two models you can also get tires in 245/335 sizes
If you have concerns about the Toyo tires wearing out too soon I would ask you just how many miles do you intend to drive each year? For most of us even if the tires only lasted five or 10,000 miles that would be many years of enjoyment
I am afraid even with a lot of searching you will not find an option any better than those two listed above. Good luck
