Stock 195 50 17 should be 24.7 tall 205 55 17 is 25.9 tall (it will be too big) You always better off looking at 2154517 which is 24.7 tall.
The 215/45/17 would be good, great or poor alternative? Any thoughts on mpg (or any) effects on this tire size difference to stock on an LE? I am clueless about these type of changes and the results
