Ignoring the Silverstone results, entirely, is probably the best option right now. DJ’s test and the Cyclingnews test produced results that were opposite each other, and at the same time each result went against prior testing. The SSE-PER don’t seem applicable, because what can be applied from the two tests?
- Wide XC tire suffers an extreme penalty on pavement - DJ Result
- Wide XC tire offers a benefit on pavement - CN Result
- As tires become wider the power requirements increase - DJ Result
- As tires become wider the power requirements decrease - CN Result
If you showed a tire enthusiast the points above and told them one tire was a Race King and the other a Terreno Dry they’d say obviously because the Race King would have the good result and the Terreno Dry the bad. Which is opposite of what the SSE-PER actually found.
Obviously these results are influenced by the tires themselves, but when DJ was testing what is generally considered the 2nd fastest XC tire, and CN was testing one of the slower XC tires - the relevance of both tests is questionable.
And this is before the issues that come from the cobbled surface used. Fundamentally, the SSE-PER is another type of roller test, and there isn’t enough data to tell if we should pay attention, or not.
