List 1B/1C - V70a

[Output Flange]

MSA tyre list 1B has this entry for Kumho tyres:

MSA said:

Kumho
- Ecsta V700 (including V70A) (OE Fitments 215/40/17 only)

Firstly, I thought the V700 and V70a were the same tyre?

Secondly, does that mean that the only size you can run is 215/40/17?

Further down on list 1C it says this:

MSA said:

Tyres listed on 1b as valid for cars first registered before 01/10/1990 are valid in 1c where fitted to cars first registered after 01/10/1990.

Kumho
- Ecsta V700 (including V70A)

So it looks like if I want to run V70a on my car registered before 1990, I can only run 215/40/17?

The Kumho is a 1c tyre, and can be used in any size and on any car under those regulations.

Thanks. Why is it listed in 1B and 1C then?!

[df76]

Because it's allowed in 1b in only one size (which I believe was OEM fitment on a Mini GP2, so that need to be retained on List 1b).

Up until this season it was one of the tyres of choice amongst the hillclimbing/sprint fraternity, but now due to it being list 1C it may be on the wane a little.

Stupid thing is you can't get them in some of the sizes anyway! Same as Toyo who advertise a new tyre but not available in all advetised sizes. I've been knocking my head against a brick wall with tyres. Had Kumho's and Toyos on order since December '15 with a "very big" motorsport retailer near to me and still have not got a tyre yet even though they were promised in 6 weeks.

Hopefully a well known Blackpool motorsport tyre retailer has come to the rescue, will know for sure tomorrow
