Choosing 2003 Toyota Highlander Tires

Other than getting the proper tire size, you also want to consider a handful of other factors when buying new Toyota Highlander tires like where and how you drive, and what tire brand you trust most. When thinking about your driving conditions, consider where you live (mountains vs. city vs. countryside) and the kind of weather can catch you off-guard. (Watch out Tornado Alley!) Many drivers who live in states that experience all four seasons choose to purchase two sets of tires: one set for winter, one set for summer. Other drivers prefer the convenience of all-season tires. They make one trip to the tire shop and they're pretty much ready for rain, light snow, or sun!

Next, consider your driving style. If you're a diehard off-roader, you have very different tire needs than a highway commuter who doesn't leave the paved path. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for Toyota Highlander tires online.

During the first few years you had your 2003 Toyota Highlander, you and your passengers probably enjoyed a ride that was smooth and balanced. But these days, things are starting to feel a bit rough. Maybe your Highlander jolts, drifts to one side, or makes an unusual noise when going over a speed bump.

2003 Highlander Steering & Suspension Q&A

  • Why is my Toyota Highlander bouncing excessively? Damaged struts or shocks can't dampen road bumps properly, causing your vehicle to feel like a trampoline after each dip or bump.
  • What can cause the front end of my Highlander to dip forward when I apply the brakes?  When you brake, the forward momentum combined with your vehicle's weight sends a lot of force to the vehicle's front end. A bad suspension can cause all that weight and force to push the front end downward.
  • Does tire pressure and tread depth impact my Toyota's suspension?  Maintaining your tires can help reduce strain on the suspension, nd also let you know when it's time to replace your tires. A faltering steering and suspension system could lead to uneven tire wear.

Frequently Asked Questions for 2003 Toyota Highlander A/C Systems

  • What’s making my Highlander A/C put out warm air? If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.
  • What causes A/C system leaks? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Highlander’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Why won’t my Highlander’s A/C cool the vehicle when the car is stopped?  If your A/C only works when the vehicle is moving, there could be a problem with part of your Highlander’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.
