Wet tyre wear

My second race as a newbie is looking like a wet race. I was just wondering what the wear rates are like for wet tyres as I want to make sure I do the right amount of stops?
Im in Malaysia for a 28 lap race doing 2 stops, but will my wet tyres last? I imagined wet tyres last a lot longer due to low temperatures and speeds? Is this right as the only thing I have seen for guidance is a screenshot of the 'strategy thing' which seems to show they wear at 14% per lap? This is seems wrong to me!

ps. Have searched the forum, couldn't find anything!

For wet tyres it's often about 2 to 3 % wear per lap so your wet tyres will last.

they'll last less now Tjerk I think after the update, did a full wet race with the bar fulled yesterday and tires were under 50% after 10 laps at China.  Where as a 1 stopper would compete with a 2 stopper before the update, I think a 2 stopper is now a better choise on almost every track.

So whats the consensus then haha?

I'm also eager to learn the wear rate of wet full tires. Looks like it may rain this evening...

My fears were realised. Qualified last after qualifying 2nd last time and finished last by 3 laps. Also had to do 3 stops due to tyre wear being 20 a lap...
Is there any way of looking back at the race to see if it actually was a wet race?
Also, when is it wets and when is it intermediates? It was supposedly "heavy rain" 80% chance so I went for full wets

Right. Seems that the wear indeed has changed a bit since the tyre update. Had a wet race yesterday and there it was around 5% wear a lap which I feel still is quite allright.

There's no way to look back at what the weather was in the game, but as I understand it, iGP gets its weather reports from Weather Underground. The live weather given in the game is taken from the current conditions at the weather station closest to the circuit in real life.

(This bit is fairly advanced.) You can get Longitude and Latitude from Wikipedia. The game calendar is based on the 2009 Formula One season, so you can go to that article and look up the circuits if you don't know them (I don't know what your experience is with F1). Weather Underground has a feature called Wundermap that is weather conditions placed atop a Google Maps-style map. Wundermap also shows you where the weather stations are, and at the very least you used to be able to click on a station in Wundermap, and the window that came up linked to a page that showed that station's report over time. (Weather Underground recently launched a site redesign and I'm not familiar with the new one yet.) I track back to find the last report before qualifying or the race to tell me the conditions if I can't attend in Live Timing. I actually wrote a Greasemonkey script that modifies the Next Race page to link that page's live weather report to Weather Underground for the closest station, in case the weather might change (for instance, it might be raining now, but the track might be dry in 3 hours when my race actually starts).

Looking over your race's results, everyone else in your race went with Hard tires and was fairly competitive. Based on your lap times, I can tell you that the weather was dry. You started on Intermedate tires, and were slow, and then when you changed to the full Wets, you were slower. Neither of the wet weather compounds work when the track surface is dry. It takes experience to really know what to do when the weather changes, and even after nearly two years on the game I don't have it all figured out. (I've done maybe 600 or 700 races across three accounts and only maybe a dozen of them had rain.)

Wear rate is not the problem with wet tires. They will last a long time. The problem you will have is they very quickly overheat, a problem you can only see if you have paid for the 2d viewer.
So although you might be tempted to push hard as they will last, i wouldn't advise it. The inters will wear more like softs.

you can see your tyre temperatures without 2D :)

Depending on supplier, you may find that the wear rate for wets & inters is higher than you might think

ooh cheecky little hint he's giving us. I cal inside knowlege!

Really?
I went into my last race using the "timing and live control" and they didn't show. At the time my subscription was still active too.
Tires were just grey, whether my tires were blue or red in real time. My screen just showed them grey.

Or perhaps he did his own research? I tested several suppilers for tires and engines to see the changes....very interesting results

Ok, thanks for this help. However, unfortunately due to the time my races are I can rarely if ever be there for the live race. With my last race all the weather reports said heavy rain so I set for Wet Weather tyres and for the first time used the advanced settings to say if it stops raining to go onto Intermediates... Im guessing this is why I started the race on Inters!
In this circumstance, where it looks wet weather but is completely dry, how should I use the advanced pitstop thing to help me? Would an example be "if it stops raining for 5 laps set to hard tyres" or something, but will every pit stop after this be hard tyres? or like in my last race, will they then revert back to putting on Wets after the first ones?

Click on either driver in the bottom left of the "Live Timing & Control" screen. It will show you down there how hot or cold their tyres are.

Thanks ;-)

Personally, I always set the "stop raining" compound to one of the dry tires (Soft or Hard), and the "start raining" compound to Full Wet. In my experience, Intermediates are good in some situations but conditions that require the full Wets are much more common.

I try to pick my leagues based on what sort of time I have available and when I'm most likely to not have something else to do. I actually just switched leagues because my schedule has changed and the timing (time of day) and time commitment required (100% league, so minimum 2 hours investment on race day) wasn't convenient anymore. I'd say at least 80% of success in this game is just showing up to the races.

I set my Advanced Strategy the way I do because if I can't attend a race with the Live Controls, my Advanced Strategy will take over and hopefully give me the best option as far as a compromise. If a race starts dry and it begins raining, there will usually be a period where a dry tire is best, then the Inters, then the Wets. As far as I know, there's no way to integrate three different compounds into an Advanced Strategy situation (Soft -> Inter -> Wet; if you have more wet weather experience than I do feel free to disagree here). When it starts raining, dry tires start cooling off and losing pace, but typically you can wait about two laps without losing too much time, and then switch to full Wets before the conditions are right for them. You have to keep in mind that in a mid-race weather change, it might be better to run the Softs or Hards a bit longer than is typically wise, then switch straight on to the Wets. I'll give you a couple of examples...

Example 1: (I'm making this one up.)

You've got a very small lead (say, two seconds or less). You're coming to twelve laps left in the race, and it starts raining. Your closest competitor pits immediately, and takes Intermediate tires. It's raining at a rate that in one lap (so 11 to go), the Inters will be faster, but only for five laps. That will leave six laps at the end where the (full) Wets are best. It's probably prudent to stay out on dry tires for two laps, then pit with nine laps remaining and go straight on to the Wets. That means you lose time for about two laps on your dry tires, and three laps on your Wets, but it saves you an extra pit stop. If a pit stop costs you 23 seconds on the track (which is a typical situation), you can give up a few seconds on track to save the extra stop. You pit with nine laps left and take Wets. You've lost a bit of time on the dry tires, and your rival removes your two second lead, and you rejoin the track on a slower tire and a one-second deficit. Your rival will be quicker, but in three laps it will be too wet for the Inters and he'll have to pit again for Wets. He pits again with six laps to go and takes full Wets this time. He pulled out a six-second lead before pitting, but now he's giving up 23 seconds by making a pit stop. You retake the lead, and it's now 17 seconds instead of two, and you've already got a bit of temperature in your tires. There's no way your rival will gain 17 seconds in 6 laps. It's an "easy" win.

Example 2: (This one actually happened to me some time back.)

I had a race in Singapore where it started raining. I was in a private league at the time, in the Pro tier. I had started the team (actually, it was the team for the account I'm posting from) the season before and got promoted after my first season. I ended up changing leagues to help my friends fill out their grid, but I was up against stronger competition. Most everyone else had at least an extra season of experience, and I really only had the staff and equipment to fight for the midfield and score occassional points. (Less experienced/trained driver, didn't have KERS, etc.)

This particular Singapore race, the rain came on lap 27 of 30. I was running 8th, in a pretty tight pack. I looked at what the weather was doing, and I realized that for the rest of the race, I was going to lose about 5 seconds per lap by staying out (so 15 seconds total), but a pitstop would cost me about 24 seconds on its own. I decided to stay out on my Soft tires, and ended up gaining a spot and finishing 7th, as the 2nd-place driver pitted and exited the pits a few seconds behind me, and there he stayed.


Hopefully that gives you some insight into mixed-condition racing, and perhaps in future you can channel your inner Jenson Button and make the right strategic calls. :D
