that's an interesting read, thanks for the post

No problem! :-)

Running slicks in the dry on track days, I used to use Pirelli Corsa's as my 'wets', but not available in 17"!!

So Dunlop or 888's as track day 'wets' -any opinions?

Or cut Michelin Pilot Sport Cups???

[Burp]

Dunlops (DZ03G) aint very good in the wet from our experiance. Or in damp/cold. R888 works quite well on cold/damp track

[V8mate]

R888s are useless in wet conditions.

I think that there could be a lot of different factors in play,we found 888 better in the wet than dunlops,however 888s were new,ie full tread,also car is light,therefore quite nimble in the wet anyway.

I have heard (and read) that R888s are fine in the wet but hopeless in standing water. I have hillclimbed on them in the wet but have yet to put the standing water to the test thankfully.

I have and can concur that they are positively in standing water. I'm quite content with them in damp conditions, but actually find a good quality road tyre such as Eagle F1's or Pilot Sports to be best in very wet conditions.

i think you have to draw a line some where,a lot of tyres are useless in standing water,having said that i once practiced a car on very expensive wet race cars ,set a brilliant time in the rain,circuit dried out,tried to save tyres,ruined them in the end,as the circuit dried out other drivers beat my lap time. The answer is 3-4 sets of tyres which is not what we are debating.

[TobyLaRohne]

I was wondering if anyone had an update on this?...are Dunlops still the daddy when it comes to dry circuit performance? Is there anything else out there that is better?

Specifically I was looking for people who've seen some kind of tangible gain from switching between r888's to dz03g's

Never used 888s' but have used DZ03 and they are very good in the dry, last long and ideal pressures for racing are around 24/25 psi any higher and they overheat. (mine were 285 30 18 on the back)

As for wet use, you can't really compare two tyres that both have the bare legal minimum tread cuts and therefore huge tread blocks, side by side. They will both be awful when in comes to dispersing water (aquaplane) and the logical step is to put wets on or use a good road tyre (non List 1b)

Is that the cold pressure?

[Oilchange]

Yes, I ran about 30 psi at Anglesey, too much and the tyres overheated, went all greasy on me. Dropped them by 5 psi and all was good

[NJH]

I have both here. The Dunlops are pretty hard rubber on the durometer, as hard as road car tyres. The R888s on the other hand are very soft, similar reading on my guage to Pirelli competition tyres (slicks/wets). I think this explains why people say the Dunlops are not good in the cold whereas the R888s overheat more easily.

[staceyboy]

As long as you're not clearing standing water the R888's are great in the damp. You just need to MTFU and get some heat in to them

[TobyLaRohne]

For me there isn't much chance of having to deal with standing water.

Has anyone seen a tangible drop in time or at least witnessed it through switching from R888's to Dunlops?
I only ask because the Dunlops are roughly a little more than Double the cost of R888's (we get Toyos at a heavy discount)...but if the championship is close towards the end of the season and I can get a second a lap extra out of the switch it could potentially make me alot of money.

What's the winners purse like?

Sequins with mother of pearl badges and it comes with a lovely strap with "nr1" embroidered on it...why do you ask?

[Pingman]

Any conclusion to this guys?

[Veesix75]

Toyo have just released a new version of the r888 which they claim does not overheat as quickly as the old 888. I have a set but not used in anger yet. Haven't used dunlops for years.

On the old r888 I set cold pressure to 26 front, 28 rear on a 775kg front drive car on 13 inch rims.
