Accelera 245/45 R17 99W PHI 2024

Accelera PHI 245/45 R17 99W is a high-performance road tyre designed for passenger vehicles requiring a wide footprint, responsive steering and stable behaviour at higher road speeds. This exact 245/45 R17 configuration carries a 99W XL designation, providing a maximum load capacity of 775 kg per tyre and a maximum rated speed of 270 km/h. The 245 mm width and 45-series profile give it a distinctly road-oriented balance between cornering response and everyday driving characteristics.

About Accelera PHI 245/45 R17 99W

The PHI is Accelera's high-performance, all-season tyre for paved-road passenger-vehicle use. The exact 245/45ZR17 99W XL specification has a 7.5-inch measuring rim, 243 mm section width, 652 mm overall diameter, 8.0 mm tread depth and 44 psi maximum inflation pressure. The XL construction increases the load capability of this configuration, making the complete 99W designation important when checking vehicle compatibility.

Tread design and steering response

The PHI uses a straight medium centre rib, dynamic medium lateral groove and shoulder blocks. Accelera's design approach focuses the centre rib on dry-road stability and flexibility, while the lateral groove is intended to support wet handling and rolling resistance. The shoulder block arrangement contributes to cornering stability and is also designed to help control tread-generated noise. The tyre is intended for paved roads rather than demanding off-road conditions.

Dry-road handling and cornering

The 245 mm footprint provides substantial road contact, while the 45-series profile keeps the sidewall relatively low compared with taller passenger-car configurations. This combination can provide a more immediate steering response and stable cornering feel. The 99W XL construction provides a 775 kg load capacity per tyre and a 270 km/h speed rating where this specification is approved for the vehicle. Actual handling depends on suspension condition, alignment, inflation pressure, load and driving style.

Wet-road traction and braking

The PHI's dynamic lateral grooves form part of its wet-road design, helping manage water while maintaining road contact. The exact 245/45R17 version is published with a UTQG rating of 400 AA, consisting of 400 treadwear, A traction and A temperature classifications. These are comparative UTQG classifications rather than guarantees of a particular braking distance. Wet performance can also vary with temperature, pavement condition, vehicle systems, tyre pressure and remaining tread depth.

Comfort, noise and everyday driving

The 45-series sidewall gives the PHI a relatively responsive road feel while retaining more cushioning than lower-profile performance sizes. The exact manufacturer listing identifies 70 dB external rolling noise for the 245/45ZR17 configuration. The shoulder design is intended to reduce road noise, although perceived cabin noise depends on the vehicle, road surface, suspension, tyre pressure and alignment. This makes the configuration more suited to drivers who value road response over maximum sidewall cushioning.

Who should consider this Accelera?

Accelera PHI 245/45 R17 99W is suited to drivers seeking an all-season performance tyre with stable steering, dry-road flexibility, cornering support and wet-road capability. It may not be the preferred option for dedicated winter driving, serious off-road use or buyers specifically requiring run-flat mobility. For customers using Dwbtyres to buy car tyres in UAE, the vehicle placard and current sidewall markings should be checked before ordering. Buyers comparing Accelera Tyres should match the complete 245/45 R17 99W XL specification.
