Extreme VR 2 Tyres

In a previous thread there was some discussion about Extreme VR2 tyres and that they are now on the MSA List 1B. There was also a question whether or not they were 'E' marked.

Thread - http://www.uphillracers.com/showthread.php?t=13927

My tyres arrived this morning (4 days delivery from Poland):

Yes, they are 'E' marked (R5 - soft compound).

Yes, they are soft - much softer than the R888Rs that I have on the car at the moment.

I will be at the Clay Pigeon sprint on Sunday 2nd - let me know if you want me to bring one along for a looksee.

Also what's the actual physical width of the tyre?
My 205/50/15 888's come it at 212 when measured.

Answers ....

My bathroom scales say they are 8.1 kg each (195 x 50 x 15).

Overall carcass width is 203 mm. I would estimate the contact area is just over 195 mm.

The only concern I have is that the tyre states 'Motorsport Competition Tyre' - see image below.

As it doesn't say 'Motorsport Competition Only' and its clearly E-marked then its OK for the road .... but I think it may be questioned.

My 205/50/15 R888's weigh in at 9.0kg each so not much in it.

I can't see it being an issue as they are on the 1B list and E marked, that's the two qualifying criteria for running in Road Going.

I'd really like to know what carcasses they use when making them as sidewall stiffness will play a big part in how they handle although I like the idea of then being really soft.

Yes ... you are right. I think the acid test will be when I put them on the car in a few weeks time. Also remember you can now get the VR2 with new carcasses. Might be worth an enquiry on what the new carcasses are .... but again until they are on the car it's going to be difficult to judge their performance.

Do they come in 13 inch? I wouldn't mind trying them on the Westfield if they're any good.
