The rims are the OEM rims with hubcaps that came with the car in 1974. They're 14" but I haven't been able to find the width. I'll take some pics. Thanks!
I'm now the keeper of a 74 260Z that has spent the last 20 years in a friend's garage. The tires have been leaking air and I discovered why - the date code says they were made in the spring of 1982! Looks like there isn't much available to replace the 175-14 that are on it, and the forums suggest an easy fix is to get new 15x7 rims and some more modern tires. Any advice on brands or sizes of either rims or tires is very welcome. Thanks, Dennis
