Need 295/40 R21 tyres in Birmingham or the West Midlands? TT Mobile Tyre Fitting 24/7 supplies and fits 295/40 R21 tyres for performance cars, prestige SUVs and high-specification vehicles at your door — 24/7 across the West Midlands. This is a wide, specialist size and we stock it in leading performance brands recommended by vehicle manufacturers.
295/40 R21 is a wide, high-performance tyre size fitted to performance cars, prestige SUVs and sports variants, including the Porsche 911 (rear axle), Lamborghini Urus, BMW M5 Competition, Bentley Continental GT, Range Rover Autobiography, Mercedes-AMG GT and other ultra-high-performance and prestige vehicles. The 295mm tread width generates a large road contact patch that is essential for the lateral grip, braking performance and handling stability demanded by high-power vehicles.
Understanding what the numbers mean: the first figure — 295 — is the tread width in millimetres. The second — 40 — is the aspect ratio, so the sidewall height is 40% of the tread width, giving this tyre a low-profile sidewall that blends sporty handling with everyday practicality. Cornering response is crisper than on standard-profile tyres, while still offering reasonable protection against the kerbs and potholes common across the West Midlands. The "R" stands for radial; the final figure — 21 — is the wheel rim diameter in inches.
At this size and performance level, tyre choice is critical. We fit premium performance brands that manufacturers recommend and that achieve the highest independent ratings for this category — including Michelin Pilot Sport 4S and Pilot Sport 5, Continental SportContact 7, Bridgestone Potenza Sport, Pirelli P Zero (PZ4), and Goodyear Eagle F1 Asymmetric 6. These tyres are engineered specifically for high-speed performance, progressive handling limits and exceptional wet-weather braking — qualities that matter significantly in vehicles producing high power outputs.
We will advise you honestly on the right fitment for your specific vehicle, trim level and use case. For some vehicles in this size range, mid-range brands can be appropriate; for others, using anything below the recommended specification creates a genuine safety compromise.
