My 2016 GTI base 6 speed with 225-45/17 wheels and factory Continental tires which has around 3,000 miles on the odometer has very poor directional stability when travelling at higher speeds. Accelerating from 50 to 80 mph on straight, good freeway type driving produces very unsatisfying squirming. The car feels very unstable, I am wondering if this factory 17" wheel tire combination is not sufficient for the power the GTI generates?
We have a 2015 Jetta 1.8 Tsi, 5 speed manual and a BMW 325is which both have the same size tires but are extremely stable at all speeds. Could changing to the 225-40/18 fix this problem? Car is fine with aggressive low speed driving, just bad on the freeway and just while under acceleration. Has anybody else experienced this and are there any ideas as to a cure?
