I really cannot believe even the worst tyre fitter would damage an abs sensor simply taking wheels off and puttting them on again.
Have you checked the tyre pressures on all 4 tyres?
And you say plenty of tread left on the rears, but how much?
How many miles have you done with the Goodyears fitted?
Have you had a 4 wheel alignment done?
They are two makes of tyres with different construction and compounds and the way the roads are remaining greasy at the current time I can tell you that even having one of the best cars made for traction/grip on 1000mile old MPSS, I'm spinning the wheels a lot more easily these days.í ½í¸„
