Tyres & wheels frequently asked questions
How much air should I put in my tyres?
One of the biggest mistakes people make is to set the air pressure in the tyres based on the sidewall of the tyre. You’ll find the proper tyre pressure for your tires on the decal (placard) located on the driver’s side doorjamb. Please note that your placard may be located in your glove box.
One of my front tyres has a bald spot, but the tires are only a year old. Why would this happen?
Uneven tyre wear can be caused by too much or too little air pressure, problems with alignment or balancing, or problems with steering or suspension. We’ll be happy to take a look so we can help your new tires last a lot longer.
Do I really need a separate set of snow tires if my car has all-weather tyres?
Snow tyres are built to handle harsh winter weather, and they have the muster to conquer icy hills and abrupt, unexpected stops. The decision is really a matter of how often you drive in true winter conditions, although we recommend that you always err on the side of caution.
I drove over a nail and had my tyre professionally repaired. Is it dangerous to drive on a repaired tyre?
As long as the tyre was repaired to the Rubber Manufacturer’s Association (RMA) standards – which is the only way we repair tyres at Exan – you should be good to go. RMA says to repair a flat tyre if: 1) the puncture is 1/4 inch or smaller; 2) it is located on the tread (not the sidewall); and 3) it doesn’t overlap with an existing tyre repair.
How often should I rotate my tyres?
According to most maintenance schedules, tyres should be rotated with every oil change. Check your owner’s manual, or an Exan service technician can tell you the exact tyre rotation time interval to follow.
How can I tell if I need new tyres?
If you notice any of the following, it’s probably time: 1) uneven tyre wear, 2) cracking or bulging tyre treads or sidewalls, 3) anything poking into the tyre, 4) tread pulling away from the body of the tyre or 5) worn treads that don’t pass the 5p test.
How do I use a 5p to determine when I need new tyres?
Stick a 5p in the tyre tread, top first. If the tread doesn’t touch the queens head, your tyres are worn and likely need to be replaced
My car sometimes shudders when I am going faster than 40 mph. I feel like it’s my tyres, but I just put air in them. Can you help?
We’ll know for sure after a quick inspection, but based on your description, it sounds like you might need to have the balance of your tyres and suspension checked.
