How Danny works at Tyres HQ
Danny reviews the hands-on guides, fitting, balancing, pressure and wear, and checks them against what actually happens on the ramp. If a guide describes a job in a way that would not survive a real workshop, he flags it. He also leads how tyres are compared for our reviews, so recommendations reflect fitting reality, not just lab figures.
Every guide on Tyres HQ goes through two people before it is published: a subject specialist who reviews the advice against real-world experience, and our managing editor who checks every fact, figure and tyre size against its source. We work from official UK sources and independent tyre tests, and never publish a number we cannot stand behind.
You can read how this works in our editorial guidelines and in how we review tyres. Spotted something that looks wrong? Our corrections policy explains how to tell us.
