Frequently asked questions

Your questions answered

Can a sidewall puncture be repaired safely?

All though there are restrictions the answer is yes in most cases, as long as it is done properly. Most shops will tell you it can’t be done. This simply is not true. We not only can repair sidewalls but we guarantee the repair for the life of the tire.

How often should I have an oil change done?

In years past the golden rule was every 5,000 km.

With today’s vehicles most manufacturers now recommend every 10,000 km or if your vehicle is equipped with an oil change monitoring system, when the indicator light comes on.

When should I tune-up my car?

With the advances in computer controls of your car’s engine there really is no set time or distance

The most sensible advice I could offer is, when you notice a drop in fuel economy, hard starting or the engine begins to run rough

In other words “If it ain’t broke don’t fix it”.

How often should I check my tire pressure?

We recommend at least once a month and only when the tires are cold.

The reason for this is because as the tire heats up the tire pressure increases.

What tire pressure should I keep in my tires?

This depends on the type of vehicle and the position of the tires.

We recommend you follow the inflation listed on the placard found on the driver’s side door post.

However, if in doubt a good rule of thumb is 32 psi for most passenger tires and 50 psi for most 8 and 10 ply light truck tires.

How often should I rotate my tires?

For most vehicles tires rotation is recommended every 10 to 15,000.

What is the difference between balancing and alignment?

Balancing compensates for the imbalance in your tire assembly by putting a counter weight opposite the heavy spot on the tire assembly.

This decreases or eliminates harmonic imbalance in a rolling tire. Alignment has to do with the mechanics or your vehicles suspension and steering. Proper alignment makes sure the tires are running true on the road. Misalignment leads to rapid premature tire wear.

Do I really need to have my tires balanced?

The answer is absolutely yes. Balancing gives you a smoother ride, reduces wear and tear on your suspension and extends tire life.

Is there any real benefit to using a brand name tire over an off brand tire?

With today’s manufacturing techniques the answer would be no. Let me explain.

By buying brand name product, on a tire for tire basis, you add about 15 to 20% additional cost just for the name recognition.

Most off brand tires perform equally as well as the higher priced brand name product and offer greater savings.

In fact in many instances, the off brand tire will out perform the higher priced name brand product.

Do I have to use the original tire size or are there optional sizes?

Most vehicles will allow for other tire sizes to be used.

This size difference is usually limited to no more than a 3% overall diameter difference.

To be safe check with either your dealer or one of our staff.

We have a program to identify alternate sizing options.

Where can I find the recommended tire size for my vehicle?

There are three places took look:

- the first is on the vehicle placard which is usually located on the driverside door post

- the second is in your owners manual

- the third is to call one of our staff and we will look it up for you.

How many miles can I expect to get from a used tire?

This is a difficult question to answer.

Let me start by saying any used tire sold by Peterborough Used Tires Inc. has a minimum of 6/32 of tread depth left.

This translates into at least 60% tread life for most tires.

Since most tires are rated for 100,000 km or more one can reasonably expect to get at least 50 to 60k from them.

The other part of the equations depends on your driving habits and whether or not you rotate your tires on a regular basis.

What is a TPMS system?

TPMS stands for Tire Pressure Monitoring System.

Although there are various types they basically all do the same thing which is to constantly monitor the air pressure in your tires.

Most systems compare the air pressure in all four tire and alert the driver if there is variance of one or more tires that falls outside a preset limit.

This could mean that one tire has more pressure in it than the others or doesn’t have enough.

Some systems will alert the driver as to which tire is the problem others merely alert the driver to the problem without identifying which tire.

Why does it cost extra to change a tire equipped with TPMS?

There are two main reasons.

The first is that to do the job right takes longer than a tire not equipped with TPMS and the other is that TPMS sensors are expensive and fragile thereby adding risk of causing damage.
