Run-flat tyres are increasingly being fitted as standard equipment on vehicles, but it’s no secret that not everyone is a fan, whether it is because of the hard ride they deliver or the cost of replacements.
Sunday Times reader RT from Stockport falls into this camp and he wrote to the Driving supplement team to ask for advice. He posed this question: “I would like to swap the run-flat tyres on my BMW 320d for conventional ones. To spread the cost, would it be safe to change the two rear tyres first and change the front two at a later date?”
Dave Pollard, motoring agony aunt for the newspaper, replied: “Run-flats are designed to resist collapse if punctured, allowing drivers to continue on to the nearest garage rather than having to call a breakdown company or change a wheel by the side of the road. They also provide protection against blowouts.
“Their biggest drawback is that they tend to give a harder ride than conventional tyres. If one is punctured, the car must be driven at a reduced speed – usually a maximum or about 50mph – for no more than 50 to 100 miles, depending on the make. Most manufacturers advise against repairing run-flat tyres, as the sidewall may have been badly damaged by the time the car has made it to a garage.
“The industry safety body TyreSafe advises against switching from run-flats to conventional tyres, as does BMW, arguing that your vehicle’s suspension, steering and braking have been set up to work in conjunction with run-flats. However, a spokesman for BMW did agree it was feasible.”
Pollard added: “If you opt for conventional tyres, as well as replacing all four at once, be sure to match the size and specifications of the originals, and check for insurance implications.”
