Too much negative offset (the wheel sits too far outwards from the car) can also contribute to poor handling due to additional stresses on the suspension components. The steering wheel can flick back in hard cornering causing unstable handling and a possible accident.
What offset can you run on a Miata?
That being said, you generally want high offsets for your Miata, regardless of generation. Sticking to the range of +38mm to +45mm offsets will help you avoid concerns with fender lip rub. A more aggressive +35mm should be on the lower end of the offset sizes you can use, typically for wider wheels (7.5” and above).
Does negative offset allow for bigger tires?
Negative offset wheels have the opposite effect moving the wheel and tire assembly out and away from the brakes, suspension, and body. Almost all aftermarket 4×4 wheels that are 9 inches wide or wider have a negative offset. They are typically wider than stock wheels to accommodate wider and larger diameter tires.
What size are stock NA Miata wheels?

What are the best rims for a Nissan Miata?
4×100 Wheels for NA and NB Miatas. The best rims for Miatas made between 1990 and 2005 (NA and NB generations) are lightweight, small (15-16″), and with higher offsets of +38-45mm. Technically, these wheels fit ND Miatas because of the 4×100 bolt pattern. But the 15″-only wheels here are too small to clear the big ND brake calipers.

NC Miatas (2005-2015) increased the size of their OEM rims even more, to 17”, and they stuck with that size for ND Miatas.

The factory offsets for the NA and NB Miatas (1990-2005) are +45mm for 14” wheels and +40mm for the larger wheels.
