So i have a blown tire on my set of 17"s and i need to replace it... The used tire store only has 215/50/17... would that fit my car?

 

215/50/17 is HUGE. Diameter on those is 25.46". Stock diameter is only 23.74". You will be much better off with 215/40/17. Diameter on those is 23.77" Pretty much as close as you can get to stock diameter on a 17" wheel.

If you absolutely must have a larger side wall, look into a 205/45/17.

 

If you are only replacing 1 tire you need to get the SAME size as the other 3, or your car won't drive correctly.
