2023 MX-5 Miata Pulling to One Side and Uneven Tire Wear

Vehicle: 2023 Mazda MX-5 Miata Club

Hi all,

I've got a 2023 Mazda MX-5 Miata Club, and I've noticed a couple of issues recently. First, the car seems to be pulling slightly to the right when I'm driving straight on a flat road. It's not severe, but I have to constantly correct the steering.

Secondly, I checked my tires and the front right tire is showing significantly more wear on the outer edge compared to the other tires. The car only has about 15,000 miles on it. I'm thinking this points to an alignment problem, but I wanted to get some opinions here. Could it be something else with the suspension?

ClearTheCode admin answer:

Your description of your 2023 Mazda MX-5 Miata pulling to one side and exhibiting uneven tire wear strongly suggests an alignment issue, but it can also be exacerbated or caused by worn suspension components.

Common Causes:

  1. Wheel Alignment Issues:
    • Camber: If the wheel is tilted too much inward or outward, it can cause uneven wear on one edge of the tire. Excessive positive camber (top of wheel tilted out) would cause outer edge wear.
    • Toe: If the front edges of the tires are pointed inward or outward too much, it causes the tires to scrub, leading to rapid and uneven wear and often a pull.
    • Caster: Incorrect caster can cause a pull to one side, but typically doesn't directly cause uneven wear unless severe.
  2. Worn or Damaged Suspension Components:
    • Control Arm Bushings: Worn bushings can allow excessive movement, throwing off alignment angles.
    • Ball Joints: Loose or worn ball joints can cause play in the suspension, leading to a pull and uneven wear.
    • Tie Rod Ends: Worn inner or outer tie rod ends can affect steering stability and alignment.
    • Damaged Springs or Shocks: A bent or broken spring, or a completely failed shock, can alter ride height and alignment.
  3. Tire Issues: While less likely to cause a pull and specific uneven wear without an underlying alignment issue, a damaged or defective tire could contribute.
  4. Brake Drag: A caliper that is slightly sticking on one side can cause a pull, but usually also comes with heat, smell, or reduced fuel economy.

When to See a Shop:

It's crucial to have your Miata inspected by a professional mechanic, specifically one with a good alignment rack. Uneven tire wear means you're prematurely wearing out expensive tires, and a consistent pull can be fatiguing and potentially unsafe, especially at higher speeds. The sooner you address it, the less tire damage will occur.

What to Expect:

  • The mechanic will perform a comprehensive suspension inspection to check for any worn or damaged components.
  • They will then perform a four-wheel alignment, adjusting camber, caster, and toe to factory specifications. If worn parts are found, they will recommend replacement before alignment.
