Not sure what the answer is here, but merely a rant.
Ordered 4 new tyres for my Dacia Duster.
I decided to order 235/55 R17 over the standard 215/60 R17. The rolling radiuses are identical and there is ample room to go wider. Standard wheels are 7" wide if that makes any difference and thought the extra 20mm in tread touching the road would be a pleasant addition.
Garage refused to fit them and they've had to be sent back to the supplier
When I arrived the garage was quiet and the 3 guys working there were just sitting doing sod all. I suspect it was any excuse not to work.
