RV-7A Aero Classic 8-ply nose tire

I know each pilot gets different service life out of their tires, but what kind of service life (landings) are guys getting out of their Aero Classic 8-ply nose tire,(either with tube or tubeless)? I 've gotten about 500 landings out of the Lamb (Cheng Shin) tire before changing it out with still about 3/32" tread depth in the center. I fly 99.5% of the time off of pavement. Just checking to see if it's worth it to switch.
