Our Tire Maintenance Guide

Your tires are your vehicle’s primary point of contact with the road, through sweltering heat, snowstorms, sleet, and everything in between. Tires face a lot of debris and stress, so it’s integral that you take the best possible care of them to ensure the longevity of their health. Replacing tires can be costly, and feels even worse when the replacement is due to negligence. Luckily for you, the tire experts here at Gus Brown Port Perry know a thing or two about tire health. Follow along with our team, as we take you through our recommended tips for taking care of your tires.


Tread Wear

Having even wear throughout your tire tread is an indicator of a healthy tire balance. Your tread should be checked as frequently as monthly, checking for no noticeable differences or variations throughout your tire’s tread pattern. Tread is especially important for driving through challenging elements, as your tire’s tread is what gives you proper traction and grip on the road. Having either uneven or significant tread wear is a cause for concern. If you have uneven wear, it is likely time for a wheel alignment or tire rebalancing. If your tread is significantly worn down, it’s time to replace your tires.

Tread Measurements

The listed following are general measurements that are standard indicators of tread health and safety. These measurements can easily be found with a simple tire depth gauge that can be purchased from local retailers. These measurements are used by our service team, who can also help you to identify tread wear.

  • 6/32” - tires are in excellent condition
  • 5/32” - tires may not perform as intended in wet or slippery conditions
  • 3/32” - 4/32” - replace your tires very soon
  • 2/32” - your tires are legally bald immediate replacement required

What Can Cause Tread Wear?

It’s a good sign if your tire tread is wearing out evenly across all four tires. Irregular wear can be a good indicator of something potentially wrong with your vehicle. Here’s what to look for in regards to irregular tread wear and what it could indicate:

  • Wear on Both Edges: Underinflated tires, ensure proper inflation and check for leaks
  • Wear on One Edge: Poor wheel-alignment, book a realignment with our service department
  • Wear Only in Centre: Overinflated tires, decrease tire pressure to manufacturer-suggested PSI, if you’re not sure what that is, check your driver’s manual
  • Uneven Wear: Unbalanced or misaligned tires, book an appointment with our service department
  • Saw-Tooth Pattern Wear: Poor alignment, book an appointment with our service department
  • High-Pitch Squealing when Turning: Poor alignment and/or underinflated tire
