Is it safe? 2 new winter tires instead of 4?

A very common question we get during the Fall and Winter seasons is whether someone needs four winter tires, or if they can get away with two. The simple fact is that installing two winter tires on any vehicle is quite dangerous.

You are probably better off not installing any. If a rear-wheel drive vehicle has two snow tires installed in the rear, you’ll certainly be able to get moving a lot easier. But what happens when you need to steer, or stop? You have tires on the front of the car that may not be up to the task. If a front-wheel drive vehicle has winter tires installed only on the front, it is very easy for the rear of the car to lose traction going around a corner, or under braking, which can lead to oversteering (fishtailing). Winter tires are so much more capable than the snow tires of yesteryear, and grip so much better; it is not a good idea to install only a pair. 

This leads into another area, which is four-wheel drive. Of course, four-wheel drive will help any vehicle, regardless of tires, to get moving more easily in inclement weather. You have twice as many tires clawing at the ground than normal. However, once you stop accelerating, and start to coast, or brake, or turn… Four-wheel drive is doing absolutely nothing for you other than being a few hundred more pounds to bring to a halt. This is where having a winter tire on the vehicle becomes a very good idea.

All-Weather Tires?

What is an All-Weather tire?  Everyone has heard of an All-Season, Winter and Summer Tire, but an all-Weather tire?  To be classified as an All-Weather tire, a tire needs to be first an All-Season, and second branded with the Mountain Snowflake  symbol found primarily on Winter tires.  So how can this be, an All-Season Tire that has a Mountain Snowflake. 

Where did this magical tire come from?

It all started off with a small company called Nokian years ago with a tire they called the WR.  Nowadays you can find the All-Weather tire in a few others manufacturers like, HankookGoodyear, and Vredestein to mention a few.

So problem solved, there is no need to make Winter or All-Season tire right?  Well.. it’s not that simple.  To say there is a magical tire compound is like saying there is one car on the road that can suit every need.  We know that is not the case, some tires are better in snow, some better on ice, some better for wet and some better for dry, etc.  It is prudent to know what type of tire an All-Weather tire really is.  An All-Weather tire is nothing more than an All-season tire with a compound soft enough and with enough siping to pass the minimum standards of being considered a legal Winter tire. 

Is an All-Weather tire good in the snow? Well, not as good as a dedicated Winter tire.  Is it good in the wet? Well not as good as a dedicated Summer tire.  It is what it is; a legal in Winter All-season tire.

So what we recommend for your car?  That’s a really easy question to answer by asking the right questions.  One popular All-Weather tire is Vredestein's Quatrac 3. Give us a ring at 1-877-877-1010 or contact us and we could give you a great recommendation.

Winter Tires VS All-Season Tires

This question comes up every fall, and is posed by a great number of our customers, especially living in a relatively mild winter city such as Vancouver.

The question is; do they need winter tires? Before I give my opinion, I’ll explain the advantages and disadvantages of each.

There are some common myths about winter tires. They are now called “winter tires”, and not “snow tires” for good reason. They are designed to work in climates based on temperature… Not based on precipitation. The magic number used in the industry is 7*C (or 45*F). Check out our Winter Tire Guide for a visual chart. This is the temperature in which the rubber compound in a winter tire starts to work much better than an all season compound. The compound in the winter tire is engineered to remain soft and supple, even in very cold temperatures.  Regardless of weather conditions, all things being equal, a winter tire will provide better grip levels than an all season tire in temperatures under 7*. The all season compound tends to become more stiff and hard in the cold, and therefore does not grip the road as well, even in dry conditions. The colder it gets, the more evident this becomes. 

The one disadvantage to using these soft rubber compounds in the winter tires, is they should not be used in warm weather, or else the tire wears very quickly. This is why winter tires are only recommended for cold weather use, and why a second set of tires becomes necessary for the summer months. It is important to note there is no safety issue with using a winter tire in the summer, only a premature wear issue. It is much better in my opinion, from a safety standpoint, to use a winter tire in warmer weather than to use a summer or all-season tire in cold weather.

If you look at the actual tread of a winter tire and an all–season tire, you will notice the winter tire has many more small “cuts” in it. These little cuts are called “sipes.” The sipes make the rubber tread block more flexible, which makes the tire more capable of providing grip in snowy or icy conditions. The sipes give the tire many more biting edges to grip and grab ice or snow. Some winter tires even have zigzag shaped sipes to give as many biting surfaces as possible. An all season tire does not have these sipes, at least not nearly to the extent as a full on winter tire.

Really, it is up to the end consumer to decide if winter tires are worth it to them. Of course the initial expense is higher than running an all-season year round, but since you have two sets of tires, they are each going to last twice as long so the end price is very similar. The difference in performance between a winter tire and an all-season tire in winter conditions is very substantial. It’s one of those things you don’t really believe or understand until you see it for yourself. I recommend to 90% of my customers that winter tires really are a good idea, even for only a moderately cold climate. They provide peace of mind along with simply being the right tool for the job.

Wet Traction Myths Regarding Summer Tires

15. March 2011 18:11 by TireGuy in Tires  //  Tags: ,   //   Comments (0)

For years we have heard customers state that they don’t want summer tires because of all the rain we get on the west coast. This couldn’t be more misunderstood. The modern Summer Performance tire offers enhanced wet and dry traction during spring, summer and early fall. The compounds and tread design are optimized to provide the greatest grip and abuse from the car and driver with temperatures starting above seven degrees Celsius.

The bad reputation of a Summer tire often starts in late fall when the tire starts to drop off in wet performance. The Summer tire takes longer in late fall and winter to warm up to operating temperature often generating complaints of early morning vibration and lack of grip off the line in wet conditions. This is the time to move to a Performance Winter tire.

Having two sets of tires is the ultimate in performance and safety. Optimizing the conditions for each with no compromise. This will add a little more initial investment but will allow both sets of tires to be worn out in the proper conditions. You would not want to go into winter with a fifty percent all-season but a snow tire at the same level would still offer some traction and safety.

I would recommend the new Falken 452, Bridgestone 760 and Hankook V12 from customer feedback over the past year as a good starting point. Once a customer has had a taste of a pure Performance Summer tire rarely do they move back to an all-season or as I like to call them a three-season tire.
