Space Saver Wheel and Tyre
 

My MY 13 XC90 has a space saver wheel and tyre. My MY 20 V90 Cross Country doesn't. Will the XC wheel fit the V90? I can't physically compare them as the cars are about 100 miles apart. Thanks for any help.

Don't take it as sure, but if I remember correctly SPA XC90 and V90 vehicles use 18" space saver wheels, so I assume they are the same. On the other hand, previous generation XC90 also uses 18" but it has slightly different ET offset (R18 5X108X67.1 vs. R18 5X108X63.3), so I think, it won't fit perfectly, but not sure as the difference is minimal, almost negligable.

You need to use a spigot ring to make a wheel with 67mm centre bore fit 63mm. It won't sit on the hub if the centre bore is too big.

Edit: the rings are there to ensure correct alignment, they don't take any weight.

My mistake, I mixed up ET with bore diameter.
