Holden GMC Tyre Reviews

Tyres are the only part of a Holden GMC that touches the road, and they have more influence on braking, wet grip, noise and ride comfort than almost any other component you can change. This page collects owner reviews and buying advice for Holden GMC tyres in Australia.

What to look for in Holden GMC tyres

Large cars carry more weight and usually more power than their size suggests, and the tyre has to handle both. Load index and speed rating on the placard reflect that engineering, and dropping below either to save money changes how the car behaves under brakes and in an emergency lane change.

Ride comfort and road noise are where owners notice tyre quality day to day, particularly on the coarse-chip seal used on much of the Australian highway network. A touring or grand-touring pattern generally gives the best balance. If the car is driven hard or used for towing, prioritise wet grip and stability under load over outright tread life.

Holden GMC tyre sizes and fitment

Before you order, check the placard on your own vehicle rather than relying on the size currently fitted — previous owners change wheels and tyres more often than you would think. The placard gives the original size, the minimum load index and speed rating, and the recommended cold inflation pressures. If your GMC has aftermarket wheels, the overall rolling diameter should stay within a few per cent of standard so the speedometer, ABS and stability control continue to read correctly. Because the GMC is no longer sold new, availability in the original size is worth checking early — some older sizes are now made by fewer manufacturers, and the remaining stock can be several years old. Check the four-digit DOT date code on the sidewall so you know how long a tyre has been sitting before it goes on your car.
