How to Store Your Tyres: A Vancouver Driver's Guide

Most Vancouver drivers with two sets of tyres — a summer set and a winter set — have a set sitting in storage for half the year. What you do with that set while it is not in use makes a measurable difference to how long the tyres last and how well they perform when you put them back on. Here is what proper tyre storage preparation and conditions actually involve.

Clean Them Before You Put Them Away

This is the step most people skip. Brake dust, road salt, and grit accumulate on the tyre sidewalls and in the rim spoke pattern during the season. If you store tyres with that contamination still on them, you are leaving corrosive material in direct contact with the rubber and the wheel surface for months. Before storage, wash the tyres thoroughly with a pH-neutral car shampoo, clean the rims with an appropriate wheel cleaner, and let everything dry completely. Any moisture trapped under a tyre cover or bag will accelerate rubber degradation.

Where to Store Them

Tyres perform best in a cool, dry, dark environment. UV exposure is the primary cause of premature rubber ageing in stored tyres — sunlight cracks the sidewall compound and accelerates oxidation even when the tyres are not in use. A climate-controlled garage is ideal. An unheated but dry basement works. A concrete garage floor without climate control is acceptable if the tyres are raised off the concrete, which stays cold and damp through Vancouver winters.

Avoid storing tyres directly on concrete floors. Concrete wicks moisture, and the tyre rubber absorbs it over time. If you are stacking tyres, do not stack them more than four high — the weight deforms the sidewalls of the tyres at the bottom of the stack.

Bag vs Rack: The Right Way to Store

Tyre bags — large opaque polyethylene bags that seal around the tyre — are the standard storage method for a reason. They block UV light completely, keep dust and debris off the tyre surface, and prevent the rubber from ozone cracking. Seal the bag tightly around the tyre to minimise the air volume inside, which reduces moisture accumulation. Change the air inside the bag every few months by briefly opening and resealing it.

Tyre racks are the alternative for mounted wheels and tyres. Hanging wheels from hooks on the axle hub is not recommended — the weight creates a flat spot at the contact patch over time. The correct rack position stores wheels flat, stacked no more than four deep, or mounted wheels hanging from a wall rack designed for the purpose. Tyre racks that allow air circulation are preferable to sealed bags for unmounted tyres, because they prevent moisture trapping.

Marking and Tracking Each Set

Write the position and date on the tyre sidewall with a paint marker — left front, right rear, or similar — so you know which position each tyre was in. Tyres wear differently at each wheel position due to camber, toe, and braking forces. Putting the same tyre back in the same position next season maximises even wear across the set and extends the usable life of all four tyres.

If you have different sets for different seasons, also note which vehicle the tyres belong to if you run more than one set of wheels — wheel offset and centre bore vary between vehicles.

Inflation: More Air Than You Think

Store tyres inflated to their maximum sidewall pressure, not the vehicle's recommended driving pressure. The maximum inflation pressure is listed on the sidewall — typically 44 to 51 psi for most passenger car tyres. Tyres stored underinflated develop flat spots faster, and the sidewall flexes in ways that cause the internal structure to degrade. Inflate the stored set to max pressure before you put them away, then adjust to the vehicle's specification when you remount them.

How Long Can Tyres Sit in Storage

Modern all-season and winter tyres stored correctly — inflated to maximum pressure, in bags or on a rack, in a cool dark place — are viable for three to five years of seasonal storage without significant degradation. Summer-only performance tyres that are softer rubber compounds degrade faster and are better stored for shorter periods, ideally no more than two to three years before they are remounted and checked by a tyre shop.

Tyres stored on a vehicle rather than removed and bagged degrade faster because the vehicle's weight continuously stresses the same section of the tyre sidewall. For vehicles stored for extended periods, use tyre cradles or supports under each wheel to distribute the load across the tread rather than concentrating it on one sidewall section.

When to Bring Them to a Shop

Before you remount a stored tyre set, have a tyre shop inspect each tyre for sidewall cracking, UV damage, and uneven wear patterns that may have developed during storage. Tyres with sidewall checking — small surface cracks in the rubber — should not be remounted. A tyre inspection before fitting takes minutes and avoids driving on a degraded tyre at highway speed.

JRS Auto Customs works with wheel and tyre fitting, and can inspect your stored tyres and wheels before the next seasonal change. Book a consultation to discuss your wheel and tyre storage situation.
