Two-week fun-in-the-sun adventure won't damage winter tires

Should I change my snow tires back to all-seasons for the trip or will the limited time I'm in warmer weather have little effect on the rubber?

Q: I’m driving with Bridgestone Blizzaks on my 2009 Pontiac G8 and will be making a trip to Myrtle Beach for two weeks.

Should I change my snow tires back to all-seasons for the trip or will the limited time I’m in warmer weather have little effect on the rubber?

A: Two weeks in the sun will not significantly wear your Blizzaks. Leave them on in case winter summons the strength for one last blitz.

Ensure that the tires are kept at the proper inflation because low pressures create heat, which causes blowouts.

Q: My car is two years old and has about 30,000 kilometres on it. One of my summer tires got a nail stuck on the side wall and when I went to replace it, the tire shop told me I should replace two tires, instead of just one. Why?

A: Your tires are well into their lifespan and some of the grip has gone away.

Drivers don’t really feel this as the grip slips away bit by bit. We constantly adjust for it without really thinking about it.

You want all your tires to have the same grip characteristics for good, predictable handling. Adding a new tire to the mix would give that one way more grip than the others.

Picture it like this: Think of a tug-of-war with two chubby, middle-aged guys on one end of the rope and one chubby, middle-aged guy and a strapping teenager at the other. It would not be a fair contest for control. You need two new tires.

And remember, the new ones definitely must go on the rear.
