had a problem today... I got a flat that i didn't know until my friend pointed out on the parkway. I'm not sure how long i was driving on the flat because i didn't feel any difference.. I got my tire fixed since i was near a MObil ... My right front tire has no traction anymore because i guess it got worn out when i was driving on it.. I fixed my tire but now my car starts vibrating when i hit 70mph.. Maybe my wheel alignment got fucked up???? any suggestions...
