Bridgestone 245/45 R20 103W RunFlat Alenza 001 * 2024

The Bridgestone Alenza 001 245/45 R20 103W RunFlat is a high-performance summer tyre developed for road-focused SUVs and crossover vehicles requiring a wide 20-inch fitment. This exact configuration uses XL construction, a 103 load index and W speed rating. Each tyre can carry up to 875 kg, while the W rating permits speeds up to 270 km/h. The supplied product is identified as 2024 production and carries the BMW star (*) homologation marking.

About Bridgestone Alenza 001 245/45 R20 103W RunFlat

The Alenza 001 combines road-oriented handling with run-flat capability for vehicles designed around reinforced tyres. The exact 245/45 R20 specification is an XL tyre with a 7.5 to 9-inch approved rim-width range and an 8-inch measuring rim. Its 45-series profile provides a relatively low sidewall for a large SUV tyre, balancing steering response with more sidewall compliance than an ultra-low-profile performance fitment. For Dwbtyres customers looking to buy car tyres in UAE, this configuration is particularly relevant to premium road-going vehicles where stability, wet grip and run-flat functionality are priorities.

Tread design and road contact

The Alenza 001 uses an asymmetric, road-focused tread pattern. Bridgestone positions the pattern around stable road contact and balanced performance across dry and wet conditions. Detailed groove and sipe geometry for this exact BMW-starred production variant is not sufficiently documented in the available technical material, so it would be inappropriate to attribute a more specific block arrangement to this particular configuration. The broad 245 mm section provides a substantial contact footprint for its 20-inch application.

Dry-road handling and steering response

The 45-series profile and 20-inch rim combination gives the tyre a relatively responsive feel compared with taller SUV touring profiles. The 103W XL construction is designed for vehicles carrying substantial loads while retaining high-speed road capability. With a maximum load of 875 kg per tyre and a 270 km/h speed rating, this specification has the capacity required by many larger and more powerful road vehicles. Actual steering response remains dependent on vehicle geometry, alignment, wheel width, tyre pressure and suspension condition.

Wet-road behaviour and braking

The exact BMW-starred 245/45 R20 103W RFT configuration is documented with an A wet-grip rating and A rolling-resistance rating on one exact-size listing, with 70 dB external rolling noise. Other production variants of the same size have different label results, which demonstrates why the exact version matters. The A wet-grip classification indicates strong certified wet-braking performance for the documented variant, although real-world results depend on temperature, road surface, tread depth and vehicle setup.

Run-flat construction and everyday comfort

Run-flat construction is a defining feature of this product. The Star RSC BMW specification is designed to maintain vehicle mobility following a loss of tyre pressure, reducing the immediate need for roadside wheel changes. Reinforced run-flat sidewalls can, however, produce a firmer ride than conventional construction. Combined with the 45-series profile, this tyre therefore prioritises controlled handling and security over maximum impact absorption on broken roads.

Who should choose this tyre?

The Bridgestone Alenza 001 245/45 R20 103W RunFlat is best suited to a vehicle whose approved fitment calls for this exact 103W XL RFT specification and BMW star marking. It is well matched to paved-road commuting, highway travel and drivers who value wet grip, high-speed stability and run-flat functionality. It is not intended as an off-road or dedicated winter tyre. When comparing Bridgestone Tyres, the Alenza 001 is best viewed as a road-focused SUV performance tyre rather than a soft-riding touring design.

The exact-size technical data lists UTQG 300 A A and no treadwear mileage warranty. Available production records show that this size has been manufactured in more than one country, including the United States and Poland, so the country cannot safely be assigned to an unspecified 2024 batch. The physical sidewall should be checked before publication if country of origin is required for inventory records.
