I think it just gives me an excuse to do something crazy to it

Because these wheels ain't going...

So let me get this straight, the tyre width can't be more than 26mm wider than stock, but there is no restriction on the size of the rim itself (so long as I match it with a low enough profile so as not to have the whole thing wider than 15mm from stock...

So I can go from 15" rims with a 4" profile tyre for a total of 19" of diameter to say a 18" rim as long as I can find a 1" profile tyre right?
*Numbers are made up for argument sake.

And that also means that for a VR6 who standard wheel is 6" / 6-1/2" wide you can only run a 7" - 7-1/2" tyre.


In other words, the law doesn't care if you want to run 20" rims with rubber painted on the outside, the problem is that they are too wide?

talking diameter here not width.

sounds about right. believe the diameter issue is around your speedo accuracy. most tyre places when you ask for replacement wheel/tyre combos will do the calc for you so that it minimises the impact on your speedo.

No, the tyre can be wider than the 26mm. The 26mm applies to the rim width.

26mm wider rim without the need of an engineers certificate.

You can go wider but you need an engineers certificate and these rules apply:
Up to 800kg = 26mm wider than factory
801 - 1200kg = 37mm wider than factory
1201kg up = 51mm wider than factory.

So I can go from 15" rims with a 4" profile tyre for a total of 19" of diameter to say a 18" rim as long as I can find a 1" profile tyre right?

This has to *also* correspond with the speed and load ratings of the original tyre. So, if the originals are 95Y where 95 = 692kg and Y = 300kmh then you must fit tyres that are equal or better than these ratings. If the replacement tyre rim package fit the above criteria, then theoretically, yes you can do what you have suggested.

And that also means that for a VR6 who standard wheel is 6" / 6-1/2" wide you can only run a 7" - 7-1/2" tyre.

No, the *rim* can only be 26mm wider *than the largest optional rim width that comes as standard with that vehicle*, but the tyre can be wider than the 26mm allowable for the rim. So, the largest optional rim width for your car maybe 7" rims with 215 width tyres and you can opt to go aftermarket to 8" rims but you can go to 245 width tyres, which is a 30mm difference in the tyre width.

In other words, the law doesn't care if you want to run 20" rims with rubber painted on the outside, the problem is that they are too wide?

You can run 20" rims as long as they are no more than 26mm wider than the original rim width and that the overall diameter is no more than 15mm bigger (or smaller).
