I have one that fits late model Miatas that only have those emergency tire patching kits. This is a tru-fit factory 16in donut that I bought for my 2013 MX-5 PHRT (which I do not own now) and peace of mind. This will save you in emergencies. Send me an email if you are interested. I will send you a picture and details. The tire is older but never used. It holds pressure and still has factory markings on the rim and tire thread. Email: jrcasas@hotmail.com putting Miata Spare Tire in the subject line. Thanks.
