Choosing tyre cushions comes down to one question that matters more than any other: how much does your car weigh. ALTairEGO builds three distinct sets specifically because a 1,500kg sports car and a 3,800kg classic sedan put very different loads on a static contact patch, and a single one-size-fits-all cushion can't be optimised for both. Here's how the three compare.
ALTairEGO Super — for weights up to 2,000kg
Super is ALTairEGO's best-selling set and the right starting point for most modern sports and performance cars. It's built with standard cushion thickness and rated for vehicles up to 2,000kg — a bracket that covers the Porsche 911, Ferrari's lighter models, Lamborghini, BMW M cars, and the Nissan GT-R. Like every set in the range, it's Italian engineered from a proprietary EVA compound, sold as a set of four, rated for both indoor and outdoor use, and built with full sidewall cradle protection.
Super is the right choice if your car sits closer to sports-car curb weights and you're storing it between drives, over a season, or between track outings rather than indefinitely.
ALTairEGO Magna — for weights up to 2,750kg
Magna steps up to increased cushion thickness for heavier performance vehicles — the Mercedes-AMG GT, Bentley, Aston Martin, and Maserati fall squarely into this bracket. These are cars that combine performance with genuine mass, and a cushion built for a lighter sports car would be under-specified for the sustained load a Bentley or AMG GT puts on it. Magna closes that gap with a thicker cushion rated specifically for the 2,000–2,750kg range.
If your car is a grand tourer or a heavier performance model rather than a lightweight sports car, Magna is almost always the better-rated choice over Super, even if Super's price point is lower.
ALTairEGO Leader — for weights up to 4,000kg
Leader is built for maximum protection and the widest weight range in the lineup — up to 4,000kg, with maximum cushion thickness. This is the set for classic and vintage vehicles, Rolls-Royce and similarly heavy luxury cars, and SUVs, where both the vehicle's weight and — for classics especially — the age and condition of the tyre compound demand the most robust support available.
Leader is also the right choice for any car near the top of Magna's range where you'd rather have margin than push a lighter-rated cushion to its limit.
How to decide
Start with your vehicle's actual kerb weight, not a rough guess — it's listed in every manufacturer spec sheet. Match that number to the bracket above rather than the model name alone, since two cars that look similar in size can differ by several hundred kilograms. If your car sits close to a bracket boundary, size up rather than down — the cost difference between tiers is small relative to the tyres and vehicle you're protecting, and a cushion rated with margin will always outperform one running at its limit.
All three sets share the same core engineering: Italian manufacturing, EVA compound construction, full sidewall cradling, and roughly 400% more tyre surface contact than a flat floor. The difference between them is purely how much load that engineering is rated to carry.
