It is worth doing the arithmetic on the alternative. A tyre destroyed on the M25 with no usable spare means a recovery truck, a wait on the hard shoulder, a tow to somewhere with a bay, then the tyre itself, and then getting yourself back to wherever the car ends up. That is most of a day and a bill with several parts to it. Against that, a fitter arriving with the correct size and putting it on where the car is standing is one price for one job.
The part that surprises people is that it is not just cheaper, it is usually faster. The van carries the tyre, the machine, the balancer and the torque wrench, so there is no second stage waiting at the other end. The wheel comes off, the correct size goes onto the rim, it is balanced on site, torqued to the manufacturer's figure and the pressures set from the door plate. The ruined casing leaves in the van and you drive away from the same spot you stopped in.
Run-flats need replacing with run-flats, and it matters more than it sounds. It is fitted and balanced where the car is standing, in Oakmere or wherever it stopped, the sensor is checked as the wheel goes back on, and the pressures are set to spec. We are out on the M25 near junction 24 at 2am and in Cranborne at 2pm. The South Mimms phone and the Darkes Lane phone ring the same fitter, any hour.

Sitting where it does against Junction 24, Potters Bar produces more motorway tyre failures than a town its size ought to. The default response is a recovery truck and most of a lost day, and it is rarely the right one. One fitter, the correct size, balanced and torqued at the spot where the car stopped, gets the same result for less of both.
A driver near Junction 24 had a truck booked with a long wait attached. The right size was aboard the van and the car was moving before the truck would have arrived.
A tyre wrecked against a kerb while parking. The car had not moved and did not need to. New tyre on, balanced, torqued, done.
A destroyed tyre in South Mimms on a day when no local bay was trading. Fitted on the spot rather than waiting until Monday.
In almost every case, because it is one job rather than three. There is no tow, no second appointment and no getting yourself home from wherever the car was taken.
Typically 30 to 60 minutes once the car is somewhere safe. Get well away from moving traffic first and then ring.
Common car, SUV and 4x4 sizes are carried, so most jobs finish on the first visit. Unusual fitments get sourced and you hear an honest timescale.
On the same kind of machine a bay uses, which travels in the van. The wheel is spun and weighted before it goes back on the car.
It goes with the fitter and is disposed of properly, so you are not left with a wrecked casing in the boot.
