i'll nip out an read my tyre, u want all the numbers?

yeah - as in 155/65/13 or whatever

145/80 13s are the ones on the base models, on a 13x4.5" wheel.

If you're thinking of getting some though, don't

haha lol they're crazy! Cheers toby. The dealership fitted some Sport Rader alloys, 13x5,5... No way of getting decent tyres on them!

Just wanting to work out differences in rolling radius thats all, so i can watch my speed better.

google: miata tyre calculator

It lets you type in orignal and your new size and will tell you the differnce..

E.g. My original was 145/70/13 and i now have 195/45/14.. 0.3% difference!!

Yeah at an indicated 70 i will be doing 67... Just a fraction under the limits, means i don't have to shit myself past every camera now.
