About Double Star 265/45 R21 104Y DSU02 2026

The DSU02 is designed primarily for paved-road summer driving, combining a performance-oriented tread layout with channels that manage water across the contact area. Drivers considering Double Star Tyres in this size get a configuration that prioritises everyday road stability, usable wet-weather performance and the handling characteristics expected from a wide 21-inch tyre.

265 mm Width with a Practical 45-Profile Sidewall

A 265 mm section width creates a relatively substantial footprint, which suits larger vehicles requiring this specification and helps provide a planted feel during highway driving and direction changes. The 45-profile sidewall is also important. It gives the tyre more compliance than a 35 or 40-series alternative on the same wheel diameter, helping reduce some of the harshness associated with very low-profile 21-inch tyres. It remains a large-wheel configuration, however, so sharp potholes and broken surfaces can still be transmitted more noticeably than with smaller wheels and taller tyres.

104Y Load and Speed Capability

Load index 104 corresponds to a maximum rated capacity of 900 kg or 1,984 lb per tyre. The Y speed rating represents approval for speeds up to 300 km/h under the appropriate load, inflation and operating conditions. These ratings make the complete specification important when selecting a replacement through Dwbtyres. A tyre with the same 265/45 R21 dimensions but a different load or speed index should not automatically be treated as an equivalent replacement.

Wet Grip and Road Noise

For this exact 265/45 R21 104Y DSU02 configuration, the European tyre label reports C for rolling resistance, B for wet grip and 73 dB for external rolling noise. The B wet-grip classification is particularly relevant to drivers who occasionally encounter standing water or rain, while the tread channels provide routes for water to leave the footprint. The 73 dB figure measures external pass-by noise rather than the sound level experienced inside the cabin, which will also depend on the vehicle, road surface and tyre pressure.

Best Use for the DSU02 in This Size

Double Star 265/45 R21 104Y DSU02 2026 is best suited to vehicles specifically approved for this size and drivers spending most of their time on paved urban roads and highways. It is a summer tyre rather than a winter or all-terrain product, and this specification is not identified as run-flat. Before you buy car tyres in UAE, confirm the 265/45 R21 dimensions, 104 load index and Y speed rating against the vehicle manufacturer's tyre requirements.
