I found a great deal on a set of used Goodyear Ice Navi HN in a 175-65-15. According to the tire calculator, the 175/65 has an overall diameter of 23.95 and the stock 195/55 has a diameter of 23.44. My car is lowered on Progress springs so a rough drop of 1.5". My question is would these work?

Thanks!

 

Nevermind guys, I think I'm going with 185/60/15's, Yokohama's.

 

We're not dropped so can't comment on your possible interference but our 175/65x15's are superb. better mpg and great snow traction.
I suspect however that you may get interference depending on your new wheel offset but again you may not, simply because the tire is narrower
If your offset is 50 to 55 mm I don't think you will have a problem. Good luck.
