Wets v drys
number-1 - 12/11/12 at 04:13 PM

When would you start to use wets instead of drys? How wet does it have to be? And when is it too dry for wets?

Depends on lots more varibles than how wet it is.
Type of car (weight, drive etc).
Type of slicks.
Type of Wets
How green is the surface.
Levels of standing water.
tarmac type
temperature
Driver preference/ability

And im sure many more.

If your not racing it, save your money and use road tyres.

You don't need full wets for a track day.

We use A048s in RGB for dry and damp/light wet conditions, the full wets only go on with standing water, and even then their not that good. Most of us don't bother with full wets at all, they go hard over the course of a season or two, as they don't get much use.

With a high power to weight ratio car, it's going top be a handfull anyway, best advise is stay at home and book a dry day


loggyboy - 12/11/12 at 04:52 PM

For a track day I assume?
Can you take both? in which case, do and use trial (and hopefully not error)
If you can only take one set decide on the morning, if its damp or theres a chance of rain then take the wets, if its guaranteed dry take the slicks.
Simple rules:
If its wet and you have slicks you can drive slow (or crash)
If its wet and you have wets you can drive fast
If its dry and you have wets you can drive faster
If its dry and you have slicks you can drive fastest

Cheers for the replies chaps.....one last question

Ive got wets or slicks...only 1 set due to rim issues. Would i get more out of the day with wets on a dry track, or drys on a wet track?

If i had time/funds etc it wouldnt be an issue as id have 888s


Dopdog - 12/11/12 at 05:12 PM

i would use the slicks and only use the wets if it is running water


snapper - 12/11/12 at 05:21 PM

Unless you have a full bag of talent I would use decent performance tyres with tread
Slicks in the wet is not fun and unless your racing its fun we want

Fine if you have a delorean, but if you need to make the choice blindly, its safer to go with wets.
If you do decide on drys and it pisses down, you will spend more time correcting slides than learning how to go fast round the track.
Just check the youtube
for various brands action

Theres one from someone on here somewhere, he touches a wet white line and end up backwards in to the wall.

I have done quite a few track days in my 7 and it is a handful even with wets on when it's damp. First time I drove round a track in the rain i thought 'OK, I'm gonna take it easy for the first couple of laps' as I exited the pits. I was off backwards on the first bend!

Never gone out in slicks in the 7 when it's wet, but as someone who does lots of karting (rotax) I have taken the kart out on slicks in the wet and it is just total understeer followed by snap oversteer. Good for a learning experience but not something I would do in my 7. Far too much risk of writing it off with a crash, or being rear ended by someone else because of having to go at a snails pace.

Just my 2p...


ali f27 - 12/11/12 at 06:16 PM

Hi we use avon slicks super soft for hillclimbing these still work very well when its wet if its standing water we use michelien wets we also use the wets when its very cold as you cannot get enough heat into the slicks, if your going on a track day in nov use the wets but if the sun shines you will wear them out
Cheers Ali


bi22le - 12/11/12 at 06:16 PM

Take wets. It will be bone dry then and my R888 will be great!!

Seriously though, the chances of a completly dry track are slim.

Also is this not your first track day? Your car will be rapid anyway. You dont want to be stuck with slicks only. Break yourself in gently!!


CNHSS1 - 12/11/12 at 08:50 PM

Avon hillclimb slicks are great in the damp and even rain, but dont work at all in stabding water. I cant lie and say you can drive like a berk in the wet on slicks, but they will surprise you, and will be quicker around a lap than any List B roadgoing semi slick.

As said in another post though, if not competing, then a road based tyre will be easier to handle and more progressive in its feedback


eddie99 - 12/11/12 at 08:52 PM

As above, We run slicks in damp and wet conditions and are perfect once warmish, problem is when there is standing water.


chrisni1986 - 3/7/13 at 06:43 PM

i only use wets if theres standing water and alot of spray, some circuits dry out or get a dry line very quickly tho so sometimes its catch 22, if your lucky enough to have inters it makes the decision a bit easier


mark chandler - 3/7/13 at 06:56 PM

I have some yoko 048's and old slicks, only bother with the 048's if its raining.


Dopdog - 3/7/13 at 10:25 PM

So I was right then


Rogthebandit - 10/11/13 at 12:37 PM

Just the thread I was looking for ;-)

I was at oulton the other day in the rain, loads of standing water using my 888s. It was fun but a big slide going thro Druids changed the colour of me pants. I was looking at wet tyres for next time out. I was thinking of using road tyres as all the cars there that day were getting round the corners well and getting good drive out. I just found myself sliding. Can any one recommend a decent road tyre for really wet conditions? I was going to buy a set of 13" rims for the wets.


CNHSS1 - 10/11/13 at 12:54 PM

Avon CR28 are the DBs in the wet, designed around 7Types too, used to be std fit for some of Caterhams range


Dopdog - 10/11/13 at 01:43 PM

On my striker I ran Avon CR500 in the wet I found them fantastic, also make sure you run them at the correct pressure.


Rogthebandit - 10/11/13 at 01:57 PM

Cheers for the feed back on the tyres. I'm just looking at suppliers, who do you guys buy from?


daniel mason - 10/11/13 at 04:38 PM

were you at oulton on friday with us guys?


Rogthebandit - 10/11/13 at 05:08 PM

Hi
No I was there on Wednesday. There were no places left for Friday. Wednesday was very wet but fun! I've booked oulton again for the 27th. Praying for a heat wave ;-)


eddie99 - 10/11/13 at 05:24 PM

In Championships where you can use any List 1a/1b tyre, we use Kumhos in the dry and R888's in soft compound in the wet. I've been really impressed by the R888 in the wet.

Yes a true wet avon would be better, but r888 is plenty good enough for trackdays
