Tyre Grip levels

[dening80]

Where do people think GT5's tyres stand in relation to reality? How far are grip levels inflated?(no pun intended)

I ask this after working on Nurburgring times like the GTR and Zonda's and seeing that I can beat or get close to "record" times with what should be the correct tyre.

If I can do the GTR time neatly and easily beat the Zonda time with the hard slicks, how far down do you think we should be downgrading? 1 step? 2? 3?, I can still do the Zonda time on Sport softs which is probably my limit. I'm not bad with the DFGT but I know I'm nowhere near the caliber of a test driver.

There are quite a few threads on similar subjects of tire realism.

But, what is your question? It sounds like you want to know which tire best simulates a possible real tire/car combination.

I don't think you'll get a good answer to this. Even if you did get an answer you considered valid, what could you do with the information?

I would say just pick the tires you like when racing alone, or pick the tires the lobby allows, to be competitive in multiplayer races.

I mostly use my road legal cars with comfort soft tires. That seems the most logical choice as they are supposed to be passenger performance street tires (as for example would be, Continental SportContact tires). For track-day cars or supercars I use sports hard tires, as they are supposed to be road legal, entry-level semi-slick tires.

+1 to above view

I mostly use comfort medium for all street cars. This just to have comparable times between cars.
Many sport cars tire model should be on comfort soft (max to extreme performance tires: Bridgestone Potenza RE050, Pirelli PZero) etc: from Honda Civic Type-R to Ferrari Enzo.
I use Sports hard mostly for historic race cars of the pre-slick era (Honda S800RSC etc), and for 'normal' DOT semi-slicks.
Sports soft should be extreme legal semi-slicks, like the Kumho V710 http://www.kumhoedge.com/Media/Tire/96_WebPhotoThreeQuarterLeft.jpg

Racing hard/medium/soft for race cars based on how long are real races/stints:
Hard for endurance cars: Audi obtained its pole position with 300km used tires this year, and one car completed 5 stints, more than 730km, without changing tires.
Medium/Soft for F1. F1 stints are 60 to 180km. Depends of the track/year/car.
WTCC races /DTM stints are actually around 50km, so I say racing softs.
WRC change tires every 4 special stages (50-70km) but have to last other 200-250km at road legal speed. Maybe racing medium then.
NASCAR reports tires life on 150miles. Racing medium.
Hard for historical slicks.

Offline for road cars, Sport Hard max
Offline for Race cars, Racing Hard max

Online I find Sport Soft is needed for the supercars, there just seems to be no grip even after a lap or two.

Zonda 7.2, in an online race at the High Speed Ring on Sport Hard feels like the same grip level as doing it in the rain with realisitc grip offline.

It appears from some discussions elsewhere that it can also be a car to car thing too.

It seems that 2 steps down might probably make things comparable to reality. So if I wanted the grip of harder slicks I would use medium sports and so on. It's a shame this is thrown out the window when we think tyre wear.

I struggle with the search function on here and after pages of viewing I didn't really read a clear discussion based on what I am thinking.
Have people experienced doing top gear test track times easily faster than those published using say sports tyres?
I guess what I can do with this information is have a discussion with others and have fun trying to achieve laptimes that compare to reality.

Tyre wear is a big PD fail. I hope they fix it in a future release.
For lower step tires, I don't agree about the -2 step. You have to think about 4 factors:
- here there are better drivers than some 'pro'
- track condition is everytime 100%: no dump, no dust, lot of rubber
- no fear to make errors
- kerbs, grass. The '2 tires on track' rule can break irl shocks
- imho the Stig doesn't warm tires very well before the attempt.

I guess you know Stig times are also done with standing start, not launched.

Also, the Nurburgring 7' barrier with SH tires challenge could be beaten with more than 2 stock production cars (actually, the Veyron and the McLaren F1)

I don't have much experience with racing tires, and sports soft. So it's possible they have to much grip. How are Ferrari F1 times with racing medium compared to real ones?

This is what I do, in real life the car have a skid pad specs that you sometimes find in some magazines. Once you know the skid pad/ lateral grip/ g force all the same for the real car, try the tire in the game which allow you to pull simular g force in the corners and that will give you the correct tire.

I'd actually never thought of looking at the G metre.
I guess that is the best way to measure grip, I'll definitely pay attention and look at any data I can find on the road cars.

At the end of the day some of us should be able to beat real world times as the track and car are in optimal condition, and we don't have to worry about destroying our cars or ourselves. This shouldn't enable us to beat them by mega amounts though.

There is a thread here arguing this, with very detailed informations about cars, tyre manifacturers and stuff. It seems that every car in GT5 has its own tire scale

The bad is the lack of a steering pad in gt5 and the lack of detailed informations on HOW these G forces was misured by car testers.

Without that infos, I can't be convinced I'm wrong, and will continue using the proposed scale for semplicity

Saw the pic, thats just a slick tire that someone cut 2 rings into.

Can you give me a link to that thread Duck? Searching is the only problem I have with this forum :-)

Having done a few laps swapping tyres etc and keeping an eye on the G metre earlier today, I think that the cars might have their own setting regardless of tyre. With an ISF I was getting the same corner G (just over 1) with Comfort Soft or Comfort Medium though the Medium was much slower overall, now this could be that I only maximize the corner speed to a certain degree but I would have thought I would be able to see a difference.

Click here for a link to the thread you're after, I use this tyre formula for all cars we race at my Saturday Stock Car Series event aswell, & here's the tyre chart that calan_svc made after a lot of testing.

For instance, the Lotus Elise 111R comes with Sports Hard tyres, but I've personally found skid pad data ranging from 1.03g to 1.08g for the real life car, so it should really be on Sports Medium. Now you all know why the Special Event on the Top Gear Test Track was so hard, it was on Comfort Soft!

You are right, that's the thread

Remember that skid pad testing isn't an exact science, & that you will find some difference in manufacturer claims vs the reults from different car magazine tests. Just work out the average if you find several differing numbers & then choose a tyre.

I've been using calan_svc's tyre formula since he worked it out, & have to say that every car I have drove using it behaves in a very appropriate way. Some cars come with the right tyre already in GT5, like the BMW M3 Coupe '07, but others like the 111R, Camaro & Challenger SRT8 do not.
