Just had a set of Dunlop Sport A2 Plus mounted on my wifes 92 745 turbo. The resultant shimmy and shaking were startling. Took it back to be rebalanced, and after an hour of them mucking about with them, they called me as said there was no way to get these tires to balance as all my rims, but one, were bent on the back side. I had a set of Michelin MX4's on there prior to these and it was rock solid up over 125mph and smooth at that speed. Only decided to change as the Michelins had a lot of sidewall deterioration from UV. They balanced the Dunlops as well as they can, but it sucks. Not a smooth high speed cruiser anymore. The tires grip extremelly well, and abs panic stops with them are extremelly short and quite fun. Anyone know if these tires are prone to difficult to balance?
