Tips for storing tires

Q: I have an opportunity to purchase an original set of wheels and Bridgestone tires for my 2007 CX-7 with only 15 km on them. They were removed from the owner's CX-7 in order to install 20-inch diameter wheels and tires.

I would like to use the extra set of wheels to mount my snow tires.

I was hoping to store the newly acquired Bridgestones to use when my current tires wear out.

I have read in your column that five years is about the maximum to expect with regard to tire life, regardless of mileage. Since the wheels will be in storage and not used, is there any way to extend the life of the rubber?

A: That is an interesting dilemma. Five years is about the average life expectancy for a tire, but there are no stats for stored tires. Michelin used to say 10 years was possible under ideal conditions.

For maximum storage life, keep the tires away from light and away from any electrical motors (which may generate ozone). So the furnace room for storage is out. Keep the tires cool but avoid freezing so an unheated garage is also out. I would keep them bagged.

Do not treat them with any kind of tire cleaning/shining product. Stack them on their sides and rotate them at least once a year. Before using them, check for hairline cracks inside the tread area and in the sidewall area.
