They are only temporary though. The Mini’s new winter tires arrived fashionably late, Saturday instead of Thursday, so I spend that afternoon mounting them on the car. Instead of storing them for the winter I had the idea to mount the all-seasons on the Miata so we could take the car out for a spin at least once a week or so, even if the top is up1, to keep it fresh and and not ruin those ultra-high performance summer tires which really shouldn’t be driven in temps much below 40 degrees.
I had done the research ahead of time and they would go on the car, the offfset was only 10mm different and the Mini wheels had a larger center bore diameter, but would the taller tires work on the slightly lowered car? After I installed them they seemed to fit OK. They didn’t hit the brake calipers and turning the steering wheel lock to lock didn’t induce any rubbing that I could tell. But a test drive was needed because the springs still needed to settle from the being jacked up.
I took a quick spin around the neighborhood and all seemed fine under cruise conditions. It wasn’t until I took a quick turn into a parking lot that I heard a scraping sound. Turns out at near full lock, in both directions, the tires do hit the plastics fender well liners. The problem wasn’t with differences in the offset the rim width difference, but with the taller Mini tire. They are 195/60 as compared to the 195/50 of the Miata, so the Mini tires are a whole 1-1/2″ taller or 3/4 inches a side. I have opted to leave them on because any “winter driving” we do in the Miata will be of a cruise around town variety anyway.
