Trying to figure out the tire size for the Dynamics I bought? They are 18" x 8" with 49mm offset. My car has the original springs with no plans to lower it so I'm a little concerned about getting a shorter tire without much sidewall. These are the size options I came up with:
235/45-18 -26.3" tall - Same height as the stock 235/50-17 so no speedometer error. Then I saw a new Fusion with this size tire on it and the same 8" wide wheel and it looked pretty narrow and boring. But it could have just been the tire (Eagle LS).
245/40-18 -25.7" tall - This is what the S-Type Sports ran, but I have a feeling the sidewall would be too short for my stock springs.
255/40-18 -26.0" tall - This would probably look pretty nice, but may be too wide for the fenders with a 49mm offset.
245/45-18 -26.7" tall - This seems like it would fit the bill for me. A bit wider tread than the 235/45-18", a taller sidewall, and the speedometer should be less than 1 mph off.
Thoughts?
