Wide Base / All Position
Truck & Bus Radial
D711
385/65R22.5, 20PR. One tyre carrying 4,500 kg where two used to.
The super-single. A 298 mm tread face on a 382 mm section, rated 4,500 kg / 9,920 lbs in both single and dual fitment at 900 kPa — which is what lets it replace a dual assembly outright. You buy it for the payload and the unsprung weight you get back, not for the tread depth.
