HI there,

Yes, this is a subjective thing based on availability.

The normal sizes are fronts : 265/40ZR17 Rears 295/35ZR18

I have used the following on ZO6 without issue.

Front : 275/40ZR17 Rear 295/30ZR18

The fronts are 10mm wider but are widely available.

The rears I could not obtain in 35 aspect ratio so I went to a slightly smaller 30 aspect ratio.

These are the closest I could obtain for my customer and not create rubbing issues or inaccurate ABS or speedometer issues.

Allthebest, Paul
