Right rear tire has ecessive wear and cupping with the typical 350 z tire roar. on 2003 Nissan 350Z

Shocks seem good and nothing loose or dried out.70,000 miles.I dont want to replace the tires untill the wear issue is resolved.Any ideas?
Thanks

sounds like poss low tire pressure issue. all low profile tires are subject to bad wear patterns.
needs alignment
