Top motoring agony aunt Honest John has been quizzed on the subject of ‘does size matter’ when it comes to smaller wheels!
The Daily Telegraph columnist directed TS from Newark to the etyres website, to the section where the UK’s leading online tyres company features a Tyre Size Change Calculator.
Under the headline ‘Smaller wheels means a better ride – Honest John explains why fitting smaller wheels improves ride comfort – TS asks: “You often advise people to change wheel sizes to improve ride comfort. Would this not affect the speedometer reading, thus making it illegal unless the gearing was altered to compensate?”
Honest John replied: “You have to keep the rolling circumference within 2.5 per cent. Smaller wheels allow the fitting of deeper-profile tyres. Go to www.etyres.co.uk/tyre-size-calculator.htm and you’ll find that 225/45 R18s are approximately equal to 215/50 R17s, which are approximately equal to 205/60 R16s.”
For anyone not familiar with the brilliant Honest John, he started work in the motor trade in 1959 and bought his first car in 1964. His award-winning agony column first appeared in the Daily Telegaph’s Saturday Motoring section in January 1995 and he has since helped many tens of thousands of people with their motoring problems.
