Quick answer: Treat tire-cover size and camera opening as two separate measurements. After confirming overall tire diameter, measure the widest outside diameter of the camera housing that must pass through the cover—not only the lens. Record whether the opening is centered or offset, photograph the setup straight on, and compare the result with the current selectable opening options before ordering.
A correct tire diameter does not automatically answer the camera question. The cover must fit the spare tire while the opening must clear the relevant housing in the correct position. Keeping those decisions separate prevents one measurement from being mistaken for the other.
Record each dimension for one purpose
| Decision | Choose this when | Check before buying |
|---|---|---|
| Overall tire diameter | You are choosing the cover size | Use tire-sidewall math or a verified overall measurement |
| Housing diameter | A camera passes through the cover | Measure the widest part that needs clearance |
| Opening position | The camera is not centered | Record horizontal and vertical offset from a clear reference |
| Straight-on photo | Placement is difficult to describe | Include the whole spare tire and camera relationship |
Measure the housing, not the image it captures
Measurement boundary: Tire markings describe the tire, not an aftermarket camera housing. Use Continental’s tire-marking reference for the tire code, then physically measure the actual rear camera housing and compare it with the exact opening options on the live product page.
The lens opening can look small while the surrounding housing is wider. Measure the physical part that must clear the cover. Do not infer an allowance that the current product guidance does not provide.
Describe placement with two references
For an offset camera, record left/right and up/down relationships from a stable center or edge. A straight-on photo with the measuring tool visible reduces ambiguity.
Keep notes attached to the order decision
Write tire diameter, camera diameter, and placement in separate lines. If the listing provides an order-note field for alternate placement, use plain directional language and retain the measurement photo.
Stop when the available option does not match
The current listing offers no hole and 2, 3, or 4 inch openings. If your measured housing or placement does not align with an offered configuration, request confirmation before ordering rather than rounding by assumption.
Camera-opening measurement checklist
- Overall tire diameter was handled separately.
- Widest camera housing diameter was measured.
- Centered or offset placement was recorded.
- Straight-on reference photo shows the setup.
- Current hole options were compared with the measurement.
- Unclear fit was sent for confirmation before purchase.
Where this product fits
The Flower-Fetch Dog Spare Tire Cover currently offers overall diameter choices from 27 to 40 inches and camera-opening choices of no hole, 2 inches, 3 inches, or 4 inches. Its listing says openings are centered by default and provides an optional order-note field for another position. Review the current Flower-Fetch Dog Spare Tire Cover product page for the selectable options and current fulfillment information before ordering.
