I am confused. I have read a bunch of different posts and a bunch of people referred the Altimax to me as a good rear tire. I actually purchased an Altimax RT 215/60 R15. I had a bunch of people tell me this is a great tire and my dealer could get it really cheap for me. I just dropped my tire to have it swapped and he came out and told me a 225/50/R15 is on there. He said go back and ask and make sure this is ok. I just looked and a bunch of posts say R215/60 R15. Do I have the correct tire for a 2017 RTL? I just pulled my owners manual and found it does say 225/50/R15. My bad I guess should Havel looked there first. Is the 215/60/R15 OK?
