I phoned a few of the big companies local to me to get mine fitted, a few wouldnt touch them because they didnt supply the tyres & the others wanted a minimum of £15 a wheel.
I phoned a small company about 2 miles from my home & asked about it and they fitted the tyres, balanced the wheels and even put them on the car for me all for £20.
1 Of the companies I tried would not even attempt to fit tyres to a set of 19s
