I'm certainly no Scion expert, but I believe all the Scion engines are different from the 1zz and 2zz in the Vibe.Stock Scion wheels for the xA and xB are apparently 4-bolt, so 'NO', aftermarket wheels for xA or xB won't fit a Vibe. The Scion tC apparently has 5-bolt 100-mm bolt pattern that IS the same as the Vibe, but it appears that the offset is NOT correct. It appears to be about 48mm for the Scion, and 35-40mm on the Vibe.According to a post in the GenVibe For Sale thread, the stock Vibe alloys have the following specs: 16" x 6.5", 5 x 100mm lug spacing with +39mm offset, so the offset is different.
