done 30,000 kms and finding that i`m all over the road, still has 50% of original tyres, started cupping on the inside front, rotated fronts to backs and had a good trustable wheel alignment done, this helped, but still tracks horribly, is it the crap stock tyres? i`m hoping to 275/70/16 hankooks AT before next winter, will they help? is it better to have maybe more toe-in to make it go straight????? driving me crazy............................ help please
