HILLCLIMB/SPRINT TYRES

[melv]

Has anybody had experience of following tyres for hillclimbs and sprints?

KUMHO ECSTA V70A

DUNLOP DZ03G

TOYO R888R

They will be on a '91 Porsche 911(964) Cup Car.

Thanks in advance for feedback.

I used Dunlops for racing, they took a lap to warm up so...

That's no good then!!

Hi Mel,

I'd say of those three the R888R in the soft compound will be the quickest to get up to temp.

Surely with your car though you're in a class where you can run super soft slicks?

The Kumho isn't a 1b tyre for 2016, so can't be used in the roadgoing classes...

If you are running in Mod Prod then the only thing which will get you anywhere near the competition will be Avon A15 compound slicks. You may however find it difficult to get the correct sizes for your car and end up with A50 which is the next best thing. If you are running in Road Going then it seems you may suffer from the current list 1b debacle. See on here, uphillracers and other places.

Thanks Nick. It's a thought but would need wets too and that's a PITA!!

Won't be running in road going class......

I feel your pain. I've been mulling over some super sticky R888Rs on one set and some Uniroyal Rainsports on another set as wets.

This year I ran Nankang NS2-Rs which were surprisingly good in the dry.

I think your suggested combo would be just about about perfect for 2016.

I ran "street" NS2-Rs and they matched 1a tyres to the hundredth, but I also used them on the road as an everyday tyre and they were very good in the wet. I would be tempted by the "track" version as a competition tyre. There is a new even softer compound in certain sizes, but it doesn't seem to be "E marked".

OP, what Championship are you in?
The Uniroyals are great 1A tyres, V70As were the best 1Bs but as we all know...etc etc etc. Are there any soft compound 1Bs now available from anyone? Toyo say so but try finding them.
