I have a 2005 Sebring TCI and the tires on it are 215/50R17, and the car follows the groves in the interstate pretty bad. I looked it up and I guess its called Tramlining.
Anyways, can anyone suggest a wheel or tire size that would fix this issue? I am due to get new tires and I wanted to check to see if I should get different wheels all together. Or what size of tires might help with this issue and the loud noise.
Thanks

 

Neither the wheel size nor the tire size has anything to do with the problem. It has to do with the tread pattern and the way it interacts with the grooved pavement. It's going to be something that is virtually impossible to predict. Talk with people who drive the same route and see whether their tires produce the same reaction. If you find someone who denies any problem, take a look at his tires and see if you can find some similar ones for your car.
Sebring tire clearance in very tight. Check your owners manual for the recommended tire size and stick with that. If you don't have an owners manual, download it from chrysler.com
