275/35R15 AR1 is 575mm mounted on 10.00" They will get me going initially for 1 set of wheels
Track reviews are extremely positive + read a review of someone in Germany driving 3500kms on the road with them

If you've taken that measurement yourself it's with 2mm of Nankang's published info on their site.

I wish they made the NS-2R in the same sizes as the AR-1.

575mm diameter is quite small in a Stratos arch. I'm using 585 diameter and as well as looking small, to get the correct chassis ride height at the erar the dampers are hitting the end of travel on full droop. the arch-filling tyres have a diameter of about 600 - 610mm.

I went through all this a few months ago.
The overall diameter of the Continental Premium Contact 6 that I fitted seems to be 644mm.

I am worried now though, as it appears KwikFit used the 94Y tyre and that is not one of the permitted rim sizes for my 10J wheels!.
What do I do now!!

Does anyone know if these are road legal - look a little odd for IVA?

Does anyone know if these are IVA compliant?

Michelin TB5f and TB5r are both road legal semi slicks dont know about IVA but if they are road legal you would presume IVA compliant hopefully somebody else can answer the IVA question.

Yes 600mm would be better as i'm building my own chassis with 037 type suspension / geometry, with 3 multi hole suspension pick up locations, ie 3 different ride heights i will have more scoop for various tyre diameters as I later build additional wheel sets
