Accelera 325/30 R21 108Y Iota ST68 2024

Accelera Iota ST68 325/30 R21 108Y is a wide, low-profile SUV road tyre designed for drivers who want strong road presence, responsive steering and stable behaviour at highway speeds. This exact 325/30ZR21 configuration carries a 108Y XL service designation, supporting a maximum load of 1,000 kg per tyre and a maximum rated speed of 300 km/h. Its 325 mm width and 30-series profile give it a distinctly performance-oriented road character.

About Accelera Iota ST68 325/30 R21 108Y

The Iota ST68 is an Accelera SUV tyre developed around paved-road driving, directional stability, wet-weather traction and everyday road performance. For the exact 325/30ZR21 108Y XL size, Accelera specifies a 51 psi maximum inflation pressure, an 11.5-inch measuring rim, 13.0-inch section width, 28.7-inch overall diameter and 10/32-inch tread depth. The XL construction is important because this unusually wide, low-profile configuration is designed to carry up to 1,000 kg per tyre.

Tread design and steering response

The Iota ST68 uses three interlocked tread block lanes designed to support directional stability and quick steering response. Its main longitudinal grooves provide channels for clearing water from the contact area, while exclamation-shaped sipes are intended to maintain traction when the road surface is wet. The pattern is asymmetric and primarily road-oriented, making it more appropriate for paved roads than serious off-road terrain.

Dry-road handling and cornering

The 325 mm section width provides a broad contact footprint, while the 30-series sidewall limits sidewall movement compared with taller SUV tyre profiles. This combination can produce a planted steering feel and relatively direct response during lane changes and cornering. The 108Y XL construction also provides substantial load capacity for compatible SUV applications. Actual handling will depend on suspension condition, alignment, tyre pressure, vehicle loading and driving style.

Wet-road traction and braking

Water evacuation is a central part of the Iota ST68 tread design. The main grooves are intended to move water away from the footprint, while the additional sipes support contact on wet pavement. The published UTQG rating is 400 AA, representing a 400 treadwear grade with A traction and A temperature classifications. These are comparative ratings rather than guaranteed braking distances, so real wet-road performance will vary according to the vehicle, road and conditions.

Comfort, noise and everyday use

The 30-series profile gives this Accelera a more performance-focused feel than higher-profile SUV configurations, but the shorter sidewall also provides less cushioning over sharp road imperfections. The exact size is listed with 72 dB external rolling noise in European specifications. Drivers mainly covering smooth highways may appreciate its stable road feel, while rough urban surfaces can make the low profile more noticeable.

Who should consider this Accelera?

Accelera Iota ST68 325/30 R21 108Y is aimed at SUV drivers seeking a very wide, reinforced road tyre with responsive steering and stable high-speed behaviour. It may not suit buyers prioritising maximum ride cushioning, serious off-road capability, dedicated winter performance or run-flat mobility. For customers using Dwbtyres to buy car tyres in UAE, the vehicle placard and existing sidewall markings should be checked before ordering. Buyers comparing Accelera Tyres should match the complete 325/30 R21 108Y XL specification.
