Urgent winter tire question?!?

[yunost]

As the title states I currently have a set of winters that measure 205/55/16 and I am just wondering how the fitment will be or if anyone else is running the same setup on there ST .

Just would like to know as soon as possible as I have a buyer for them that I do not want to turn down if they do not work on the Fiesta ST . Atleast that money I can cover my costs for new winters for the ST .

Let me know what you guys think .

Thanks in advance
Will,

205/50 is more ideal but this should probably work.

Those are about 4.5" more in circumference over the 205/40/17. Speedometer will be off for sure. www.miata.net/cgi-bin/tirescgi might provide you with some information on tire size changes

Ya I kinda figured that .

I just sold them anyways lol . Just going to get what the manual calls for and call it a day .

Not fit.
Diameter Variance over 6%. Over 3% is not recommended.
U can use:
16 inch:205/45/16，195/50/16, 195/45/16
15 inch:195/55/15，185/60/15

Here is a "Tire-Size-Calculator," very useful.

That size will probably rub also.
