185/70/14s on the MX
Ok i have treid runing the usual search option but to no avail so here goes, dumb noobs first post tada 
so i have just bought me a 91 miata with a Greddy turbo kit, some of you may have seen it form the gallery. I live in Helsinki, Finland and well winters are less than friendly round these parts and by law we have to run "winter tyres" in the appropriate season.
Now i have here in my Garage a set of Nokian studded winter tyres in excellent condition alas the size is a step up from the std on the car.(185/70/14)
Has anyone run oversized rubber on theirs and noticed any issues other than the obvious that my speedo will read slow? from my calculations i am only about 6-7% out so nothing too bad and still within the 10% rule of thumb.
feel free to flame suitably but i have tried to find other threads on this topic.

Thank you brains I knew someone would oblige with such an answer
alas new set of those is close to 500euro notes, they ain't worth much these days but I still like to hold on to as many as I can.
