How to Select a Trailer Hitch
A hitch-mounted spare wants a solid 2 inch Class 3 (or larger) receiver in most shops. Class 1 tubes with a 1.25 inch opening are the wrong conversation for CURT’s published spare mount.
Watch on YouTube →Thinking about a hitch-mounted spare tire carrier for Canadian roads, cottage trips, or a temporary tire that will not fit under the floor? A spare on a 2 inch receiver can free cargo space and keep a full-size tire reachable — but it also adds tongue weight, hangs behind the bumper, and fills the receiver so you cannot tow or run a bike rack at the same time. CURT publishes a hitch-mounted spare tire mount (31006) for 2 inch receivers. That carrier is not an active Shopify product on Lots of Parts today. This guide stays practical about when the idea makes sense, what to watch for, and which related CURT gear we do stock.
All four videos are from the official CURT YouTube channel (@curtmfg). They will not show the spare carrier install itself, but they cover the hitch basics you need before hanging heavy gear off a receiver.

Watch on YouTube →Good habits for any receiver accessory: clean the tube, seat the shank fully, and pin it before you hang weight. Finish with the sheet that ships with your carrier.
Watch on YouTube →A spare carrier does not replace trailer wiring — but if you also tow, keep the harness path clear so a hanging tire does not crush plugs against the bumper.
Watch on YouTube →You will not tow with a spare sitting in the same receiver. When the carrier comes out and a ball mount goes in, this video helps you set height again.
Watch on YouTube →A hitch-mounted spare is a niche tool, not a default upgrade. It earns its keep when you need a full-size tire on trips where under-floor storage is gone, when cargo space matters more than trailer duty that weekend, or when you are staging a temporary tire for a remote job. Off-roaders and cottage drivers who swap between a carrier and a bike rack often treat the receiver like a tool dock — one accessory at a time.
It is the wrong answer when you need to tow the same day, when ground clearance behind a low bumper is already tight, or when the spare’s weight plus the carrier pushes past honest tongue-weight comfort for your vehicle. If you mainly want bikes, start with the bike-rack-only guide instead of forcing a tire mount into that plan.
A steel carrier plus a tire is real weight hanging behind the axle. Treat it like tongue weight even though you are not towing: it unloads the front tires, changes how the vehicle feels in crosswinds, and can drag on steep driveways if the mount sits low. Read the tongue weight guide, then weigh the tire and carrier together if you can. Stay under the hitch and vehicle ratings, and leave margin for wet roads and full passengers.
Ground clearance matters on Canadian winters and cottage lanes. Measure from the lowest point of the mounted tire to the pavement after you set shank height. CURT’s published 31006 mount uses multiple shank holes so you can raise the tire for bumper clearance — use the highest safe hole that still clears the bumper and does not block lights or the hatch.
Any hitch accessory is only as secure as the pin that holds the shank. Use a proper hitch pin and clip, or a lock-style pin if the vehicle sits overnight in public lots. We stock CURT hitch locks such as CURT 23518 and CURT 23519 for that job. A receiver cover is a different tool — it keeps weather and debris out when the tube is empty — see CURT 22272 and the cover versus lock guide.
CURT’s published spare mount notes that tire mounting hardware is not included. Bring the correct lug hardware for your wheel, torque it, and recheck after the first short drive. Do not assume the carrier alone stops a wheel from walking loose.
CURT 31006 is the published hitch-mounted spare tire mount for any 2 inch by 2 inch receiver. It stands about 24 inches tall with slotted holes for multiple wheel patterns. That SKU is not listed on our Shopify catalogue in this pass — no product link for 31006 here. We are not inventing a listing.
What we do stock nearby: hitch locks, 2 inch receiver covers, tray-style bike racks, and a basket-style cargo carrier for weekends when cargo matters more than a spare. Those accessories still need the same tongue-weight honesty and a clear receiver.
