HANKOOK 255/70R16 Tyre Prices

At the moment, I have had the Tyres back to the fitters three times. Since fitting them, there is a vibration that goes through vehicle and worsens as the speed increases. It is intermittent and the fitters have rebalanced the tyres, checked all the wheel alignment nuts and bolts and have been in the car for a drive at different speeds......the wheel alignment guy who came for the drive recons it's not the tyres or alignment and he seems to think it's the gear box.... a six-speed auto in a BT 50? It is booked into my mechanic for the 17th of Jan and he is going to test drive and check all the running gear on the vehicle on that date. But, as he says, funny that this vibration has only started as soon as the new tyres were fitted and not before on the old tyres which were the same tyre and had done close to 87k. I will let you know more after the inspection on the 17 th Jan.
