Tire balance is more noticeable at higher speeds.Have had my 2.0 a/t koup for a week now and it's a blast, however today on the highway, noticed a slight shudder which was enhanced when i gave slight right turn input. Made no difference 3rd or 4th gear. Can't feel it below say 80 km/h. Feels like the front right wheel is about to come off, slight exageration only. I checked for stones in the tread, checked for play in the wheel but all seems good. A bit worried, looks like I will have to test Kia's claim on their extensive warranty. Any ideas what it might be?
