C5 ZO6 wheels question

[mgbrv8]

I have a very low mileage set of C5 ZO6 factory wheels like the ones pictured. If I put them on with factory C5 sized tires are they a direct fit or do they need a spacer or adapter? Is there a ideal tire size to look for them? I want them for road trips and small runs so I dont wear out my 315s. Also my car is a 91 Zr-1

Spacer and longer studs.

they work great on a regular C4...well at least on my previous 1996 LT4. Too Narrow for the ZR-1.
