What is the best way to store seasonal tires in a New Brunswick garage?

The best way to store seasonal tires in a New Brunswick garage is on a wall-mounted tire rack that keeps them off the concrete floor, away from direct sunlight, and in a cool, stable environment — and whether you store them stacked horizontally or hanging vertically depends on whether the tires are mounted on rims. With NB's mandatory winter tire season and the Maritime climate's effect on rubber, proper storage extends tire life significantly and keeps your garage floor clear for the six months each set is not in use.

Tires mounted on rims (the most common setup for NB drivers who swap between winter and summer sets) should be stored stacked horizontally or suspended from hooks through the centre hole. When tires are on rims, hanging or stacking prevents the sidewall from bearing the full weight of the tire in one spot, which can cause flat spots and sidewall distortion over a six-month storage period. Wall-mounted tire hooks that hold tires vertically by the rim cost $15–$40 per pair and hold two tires per hook set. A set of four tires can be stored on two hook sets using roughly 3 feet of wall space. Alternatively, a horizontal tire rack that mounts to the wall and holds all four tires in a stacked position costs $40–$100 and is extremely sturdy.

Tires without rims should be stored standing upright (vertically) on a shelf or rack, and rotated a quarter turn every month or so to prevent flat spots. Stacking unmounted tires horizontally puts pressure on the sidewalls and can deform them over time. A simple upright tire stand for unmounted tires costs $30–$60.

Cleaning before storage is essential in NB. Before you put your winter tires away in April, wash them thoroughly with soap and water to remove all road salt, sand, and de-icing chemicals that have accumulated over the winter. NB roads are heavily salted from November through March, and leaving that residue on your tires accelerates rubber degradation. Dry them completely before storing. The same applies to summer tires going into storage in the fall — clean off any brake dust, tar, and grime.

Tire bags or covers protect against the elements that degrade rubber. Even inside a garage, tires are exposed to ozone from electrical motors, UV light from windows, and temperature fluctuations that break down rubber compounds over time. Individual tire bags — available for $5–$15 per set of four — keep tires dark, clean, and protected. Black garbage bags work in a pinch but purpose-made tire bags are thicker and more durable.

Temperature and environment matter, and NB garages present specific challenges. Ideally, tires should be stored at temperatures between 0 and 25 degrees Celsius, away from electric motors, furnaces, and any ozone-producing equipment. In an unheated NB garage, winter storage temperatures may drop well below freezing — this is generally acceptable for winter tires, which are formulated for cold, but summer tires are not designed for prolonged sub-zero storage. If your garage regularly reaches -20 degrees or colder in winter, summer tires may stiffen and develop micro-cracks over time. An insulated and moderately heated garage eliminates this concern. Keep tires away from windows where sunlight can reach them, and never store them near solvents, gasoline, or lubricants that can degrade rubber.

Floor storage is the worst option for NB garages. Concrete slabs in Maritime climates wick moisture through the surface, especially in spring when ground moisture levels peak. Tires sitting directly on a damp slab develop flat spots on the contact patch and absorb moisture that promotes mould growth on the rubber. The condensation between the tire and the cold concrete is visible as a damp ring when you pick the tire up — that moisture sitting against the rubber for months is not doing it any favours.

A wall-mounted tire rack, a set of tire bags, and a good wash before storage — that is the complete system, and it costs $50–$150 total to set up. The whole project takes about an hour to install the rack and half an hour to prep tires at each seasonal swap. It is a straightforward DIY project that requires only a drill, a stud finder, and lag bolts into wall studs. Your tires will last longer, your garage floor stays clear, and your spring and fall tire swaps become faster and cleaner.
