From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Avon Turbospeed CR27 is primarily recognized as a legacy tire choice for classic luxury vehicles, specifically the Bentley Turbo R. User feedback highlights concerns regarding the longevity of the rubber compound over extended periods and the significant financial investment required for replacement.
Pros
- Period-correct aesthetic for classic luxury vehicles
- Original equipment specification for specific vintage models
Cons
- High cost of replacement
- Susceptibility to sidewall cracking and aging over long durations
- Limited modern performance benchmarks
Observations
- Specifically utilized as original equipment for the 1998 Bentley Turbo R in the 255/65R15 size.
- Users note that the tire's lifespan is often dictated more by chronological age and material degradation than by actual mileage.

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
