The Scion 15'' alloys are a very narrow 5.5'' wide. I want 205 tires because I may get aftermarket rims for it later. So I want to know if a tire that wide will fit or not. I think the steel rims are 6'' wide so that doesn't help me.

Tires in the size of 205/55ZR15 will normally have a "Rim Width Range" of 5.50 to 7.50 inches. For more information on the tires and sizes available for your vehicle, please visit our web site at:
