Differentsame size/ET as standard 16" rims, so would need 225/55/16 tyres
To be clear, the factory 17" rims you intend to fit have have an offset of ET33.
They require a tyre of size 235/45/17, as fitted at the factory.
The rolling radius is irrelevant, as the differences between the various sizes are negligible.
To put that another way, if it were a significant problem, then the factory would have fitted the tyres you suggest. They didn't, therefore, neither should you
You can ignore that about the speedo
The exact wheel/tyre combo in the manual depends on spec. The manual in the link is the facelift one, but I have listed the prefacelift ones too.
If you run all those tyre sizes listed through the convertor on miata.net you will see whatthe minimal differences of the rolling radii are. Anything below 2% can be ignored as the speedo is only accurate to 10%.
Being a V6 Your car would have left the factory with 205/65/15 tyres fitted, so use that size as your bench mark in the conversion calculator
you are absolutely right. thank you so much!! I went back to car manual and yes it was 205/65/15 the 195/65/15 was the spare wheel size.
Now I guess I need 215/50/17 tires and it will be OK.
Thank you All for your help, much appreciated
for your information , opel use 195 size on that year .. for GLS and CD
and also
On a 7.5J, 225 may be a shade narrow, 215 will start to look a bit shite. If tyre costs need you to go narrower, consider getting the right rims for that size.
UK insurance companies can be a bit touchy over tyre sizes not approved by the manufacturer, so you may need to declare non standard sizes (usually doesn't bump the premium too much, esp if its an optional extra size_

Apology accepted Cem, as 225/45/17 isn't an Omega tyre size
it has the same circumference with 195/65-15
but 235 45 17 is bigger apparently
