The Short Version
- 4×100 and +45 on every Vivio grade in the Japanese factory tables. Base Bistro, RX-R, RX-RA, GX-R, two-wheel drive and four-wheel drive — all identical.
- Only the diameter changes by grade: 12×4J on the plain two-wheel-drive and CVT cars, 13×4J on the 4WD and RX grades.
- Note the rim width: 4J. Not 4.5J, not 5J. These are very narrow wheels.
- The hub bore is not published. The field is empty on every grade on both Japanese databases we use.
A Kei Car With Almost No Variation
The Vivio is one of the more interesting kei cars Subaru built — supercharged RX-R, four-wheel drive, a targa-roof special, and the retro Bistro trim that has its own following. From a wheel point of view it is completely uniform.
We pulled the grade pages across the run and every one came back PCD 100, four holes, offset +45. The RX-R does not get a different offset. The four-wheel-drive cars do not get a different pattern. The Bistro does not either. The only thing that moves is the wheel diameter, and it moves with the grade rather than the year: 12 inches on the plain two-wheel-drive and CVT cars, 13 inches on the 4WD and the RX grades.

Four-J Rims Are the Thing to Understand
A 4J rim is narrow by any modern standard. It is why a stock Vivio looks the way it does, and it is why almost everyone who imports one changes the wheels immediately.
The practical window is 13×5J to 13×5.5J, or 14×5.5J if you want the diameter, in the +35 to +45 range. Because the car is a kei, the body is narrow and the arches have very little to give: at +35 on a 5.5J you are close to the edge, and that is before you consider that Japanese kei regulations require the tyre to stay within the body. That constraint disappears the moment the car leaves Japan, which is exactly why exported Vivios end up on wheels no Japanese owner could register.
Tyres are the harder problem. 155/65R13 and 155/70R12 are shrinking categories, and 12-inch performance rubber effectively does not exist. If you are buying a 12-inch Bistro, factor in that going to 13 inches is not styling — it is how you get a choice of tyres at all.
The Bore We Cannot Give You
Both Japanese databases leave the hub bore field empty on every single Vivio grade. This is not a gap in our research; the field is blank at the source, in the same way it is blank for several other older kei models.
So: measure the machined register on your hub before ordering, or send us the chassis code and we will check against a physical wheel. On a car this light it is less critical than on a Delica or a Bighorn, but a wheel centred only by its lug nuts is still a wheel centred only by its lug nuts.
The T-Top
The KY3 T-top is a targa-roofed special and it is the Vivio people ask about most. We could not find a factory wheel table for it on either database. Japanese secondary sources describe it running an optional 13-inch BBS forged wheel on 155/65R13, which is consistent with the rest of the range, but we could not confirm its offset from a primary source.
If you own one and can read the offset off the back of a factory wheel, tell us and we will add it here with credit.
Importing
The Vivio ran from 1992 to 1998, so under the US 25-year rule the entire model is now eligible. The RX-R is the grade most people want and the earliest cars — March 1992 — cleared years ago.
Worth knowing before you commit: a Vivio is a 660 cc kei car with a supercharger, and US state rules on registering kei vehicles for road use vary considerably. That is a separate question from federal import eligibility, and we cover it in the kei import guide linked below.
What We Could Not Verify
- Hub bore for any Vivio grade. Blank at source on both databases.
- Factory wheel and offset for the KY3 T-top, including its optional BBS wheel.
- The Bistro-Sport five-door CVT grade specifically, which exists in the database index but whose wheel table we did not pull.
