Hi all I have to buy a new tire and rim at the moment because my last flat tire bent my rim didn't notice and the tpms didn't go off. Anyway I have the ability to buy a pair of ridgestone pontenza 215/50-17 but my front two tires are brand new and are 215/45/17 would it make that much of a difference if I were to use the 50 on my back wheels? I need help figuring this out. Also if anyone out there knows of any good places to look for rims in tampa/st pete area. I have looked at a few ads in for sale section but for awhile I've wanted to buy all new rims curb rash on all 4 of my original. Haha so much questions hopefully someone can help me out out there.

Thanks in advance,

 

I would just stick to the stock size of 215/45R17. The 215/50 will actually be a taller tire and when it comes time to rotate, it will cause speedometer and odometer error.
