So I just got some used street rims from the zilvia forum and the rear tires have uneven wear. One tire is around 80% and the other is around 50-60%. Will this cause any negative effect on the car (driveability or mechanicaly) if I drive on these for the season?

 

Yes. Driveability is going to be a bit weird. Mechanically, no. Some nerd will come in and say "it's going to wear one side of your suspension out faster than the other". I'm going to tell them stfu and to go back to jerking it to pr0n since actual sex isn't on their agenda.



Drive them till they're dead. Replace.
