How Summer Heat Affects Alloy Wheel Performance

While winter gets a lot of attention for damaging wheels, summer presents its own set of challenges. High temperatures, hot road surfaces, and UV radiation can all take a toll on alloy wheels, particularly if they’re already weakened by age or previous damage.

As road surfaces heat up, the air pressure in tyres rises. This puts additional strain on wheels, especially if there are any pre-existing cracks or weaknesses. The constant expansion and contraction caused by temperature changes can exacerbate small flaws, turning hairline cracks into more serious structural problems. For alloys with compromised finishes, UV rays can cause fading, discolouration, or breakdown of protective lacquer.

Summer also increases the risk of impact damage. Tarmac softens in extreme heat, leading to more potholes forming when traffic wears it down. Hitting a pothole at speed can cause bends or buckles in alloys, which affect handling and tyre wear.

To protect your alloys during summer, start with a professional inspection at the beginning of the season. Refurbishment repairs existing damage, reinforces protective finishes, and ensures your wheels are in top condition before the heat hits. Choosing a durable powder-coated finish also helps resist UV fading and keeps wheels looking their best.

Regular cleaning is equally important in summer. Dust, tar, and brake residue can bake onto wheels in hot weather, becoming harder to remove and potentially damaging finishes over time. Gentle cleaning with specialist products prevents buildup and keeps protective coatings intact.

Summer should be about enjoying the open road, not worrying about wheel damage. With proper preparation and professional care, your alloys can handle the heat just as well as they handle the cold.
