Tire Size - ZR-1 Net Registry Forums

Car-nutt · 04-01-2024

Hello everyone, looking to replace the tires (front & back) on my 91 ZR1. I am looking at Michelin Pilot Sport. I was thinking of 275/40/17 instead of the 285/40/17 and leaving the rear 315/35/17. As I understand Michelin are not producing the 285/40/17. Is there anything wrong with this size (275/40/17)? Has anyone else tried this combination before or run into this problem.
