Do 18x8.5 +33 Avid.1 AV-20 wheels fit a 2018 Honda Civic Si?

On this owner's 2018 Honda Civic Si (Tenth generation), that is the setup on the car: 18x8.5 +33 Avid.1 AV-20 wheels, as recorded in the original post. The post records the suspension as Eibach Pro-Kit. This is one owner's actual setup, owner-reported from jjm0315's post on CivicX — it documents what this owner runs, not a guarantee that the same setup will fit or clear on your car.

From jjm0315's CivicX Civic Si wheel-thread post 1047099, text read verbatim Nov 6, 2026: '2018 Coupe Avid.1 AV-20 hyperblack - I wrapped the spoke red 18x8.5 +33 Stock tires still Lowered on Eibach prokit'; his postbit Vehicle(s) line reads '2018 Civic Si coupe'. All five of his attachments were fetched and viewed by me: attachment 308498 is a full-car side profile of the white Si coupe on hyperblack AV-20s with the red wrapped spoke visible on the front wheel.
