Work wheel hubcentric ring help.

[OBD1 kenobi]

Hi everyone,

Could someone please confirm that I will need hubcentric rings. (60.1mm OD to 54.1mm ID) to fit my new to me Work Equip 03 rims into my 1994 miata? Wheel specs are 15x7 +25, 4x100.

Here is the situation. I had the original hollow spoke wheels on the car until I bought these wheels 3 weeks ago. Wheels came with old but still usable chinese tires. I slapped the wheels on the car and for the first time ever I experienced the dreaded 60-70mph vibrations that people talk about. It is quite pronounced so im eliminating possible causes. Before going into chassis and suspension components I wanted to rule out new wheel issues. Tires are old and While they pass a visual inspection, they dont inspire a lot of confidence. I will put new tires soon and will balance and maybe align the car but Im guessing whether or not using hubcentric rings will make any difference. Thanks in advance for any help.
