Question about Tires in Gran Turismo 6

[Bobby Steel]

What are the comparable tires to te tires in GT6?

For instance what type of real world tire woud a Sport Medium represent AND WHY.

Ive been looking for data on tires abilities and with so many choices and such, it seems like figuring out the GT6 tires real world counterparts is going to take a long time. So Im asking incase its been done already, or there is some info I cn go on that might shorten the work load.

 

[Streeto]

Sports medium would represent a semi-slick tire with a "medium" pressure level (Psi).

It's pretty much understood that Comforts are road tires, Sports are semi-slicks, and Racing are of course slicks.

You can actually see this when you view the tires on a "premium" detail car (must have gallery view) when you switch from sports to racing tires. The racing tires, as far as I recall, show a tire with no tread, i.e slicks.

I wish we had more options instead of just 3 pressure levels, if we could change the pressure levels to our liking it would offer much better diversity.

There are lots of tuning options which I would prefer to be more in-depth, but PD have to cater to everybody unfortunately and a lot of the stuff already goes over peoples heads, even though there's detailed descriptions of what each part does within the game itself.

Kazunori said they may be considering a "pro" version of an upcoming game with deeper tuning all around for the "enthusiasts" but I'm not getting my hopes up.

I feel I might of gone on a little bit too much... sorry LOL.

Thanks, I'm looking for why each tire is comparable to the suggested real world tire.

Focused on Sport Medium and a Sports soft. They appear to have tread and not appear as semi slicks.

I'm trying to compare them to DOT Competition tires that have no real tread to speak of and while DOT approved they are pretty much slicks like G-Force tires for example. They last about a weekend at the track then time for a fresh set.

 

[TexRex]

I'd argue that the Toyo R888 actually has more tread pattern showing than that of the sport tires in the game when equipped on premium cars.

Your joking right?

Have you looked at some like G-Force? They have no tread to spread of. Slicks with DOT approval. The Toyo's have a bit of tread but less than Sport Softs in the game, the tread on SS in game looks like budget brand tire tread, cheap.

They represent different compounds of rubber rather than tyre pressure. A soft compound deforms easier to fit the surface of the road giving a higher surface area and more friction (grip) as a result. Being soft it is also easier to wear away leading to shorter tyre life. A harder compound is more resilient to wear but also less flexible and therefore cannot offer as much surface area and grip.

Comforts = Road tyres (full tyre pattern/water dispersal)
Sports = Road legal Semi-Slicks (less tyre pattern/water dispersal)
Racing = Full slicks (no tyre pattern/water dispersal)

What's funny is the pic when you buy the tires looks close to the Toyo's tread, but not the actual tires when on the car.

All Sports tires have the same tread pattern, one that doesn't look like tread off a performance tire but a regular radial.

Not even close to Toyo's the Sport Softs in the game have much more tread.

I don't know what tires you were looking at.... Are you sure about that position though????

Have another look

In game Sport Softs on a Lamborghini Aventador (premium enough?) it's tread stays like the pic from sports hard to soft.

Here is the Toyo's a pattern style much more familiar to performance tires, and much less tread than sports soft..

Why is the "why" such a difficult question to answer?

@DolHaus

Check out DOT comp tires that are practically road legal slicks. They get lower grip rating then crap tires because DOT test wet grip not maximum grip ability on a hot track.

I get the thing your saying about compounds, but tire wear off and it's all about grip level.

I look at Sport Soft like DOT Comps but how accurate is this? I don't know, seems neither does anybody else.


BUT

There is no reasonable argument to sport Softs in the game APPEARING to have less tread than Toyo R888's.

I'm not entirely sure what kind of answer you are looking for? Are you looking at them from a Replica POV (trying to match real life fitting to GT tyres)?
I don't know masses about real life tyres unfortunately, just what the various forms are roughly supposed to represent in game and how to tune to suit them.

 

[Bobby Steel]

I'm looking for the grip levels in game to be comparable to IRL.

Tire deformation if it is or is not simulated is another story but while it IS a contributing factor it is not relevant when comparing end results.

In the end each tire up is a step up in grip a step down in tire life. Each step up Cool grip goes down a bit but hot grip is more. From what I see so far.

I also see a difference in grip on older cars. Classics cars with Sport Soft are not as grippy as when on a Aventador for example. Some visually different I think too, but I'll have to check that.

I'm curious if RH might be closer to DOT Comps than SS, I would be interested in seeing IRL data of how many cornering G's a particular car can hold on DOT Comps to compare to in game Data Logger results now that we can see sustained cornering G's more clearly.

Here's a couple of things you may not know if you never hybrided.

First, there are different types of tires within each designation that are hidden from you. That is, while the game says "Sports Hards" there are actually at least 3 kinds of sports hards which you cannot see and your car could have any one of them. They each had different levels of lateral and longitudinal grip. I believe they were C and V rated if memory serves. That's why some cars like the Stratos drive like they are on ice because they have the combination of 40/60 weight distribution and the crappy (hidden) version of SH tires on the back, not the same standard higher grip SH tires that might come with an 02' RX-7 for example. And changing tires doesn't help either. C and V ratings come at all levels. So if a stock Stratos comes with Sports Hard C's and you upgrade you will get Sports Soft C's, not regular, high grip Sports Softs.

Second, all cars come with a fixed grip level. You cannot change this (unless you hybrid) , you can only tune the grip you get to it's optimum level with suspension, ballast etc. But you cannot make a 69' Vette grip like an HSC or an NSX, it's just not possible given the grip limitations programmed into the game.

So to try and figure out what tire model in real life equals what in the game it's almost impossible unless you stick with cars that are known to have the best version of each tire. Those would be the cars that do the best in the game, the NSX's, the Elise's, the LFA's etc. , all the top PP performers. When you get away from those cars, you could have a mishmash of grip and tires in unknown combinations that could skew your estimates.

 

[Bobby Steel]

On the other hand Sports Hard I look at like High a Grade Tire DOT approved and found on some cars from factory in real life. I disagree that Sports Hard to Soft are ALL DOT competition tires. What is there to support that conclusion beyond vague generalized in game description of comforts being most comparable to what cars are sold with? That is still true as most cars are sold with regular tires. That doesn't negate the fact a few cars IRL are sold with higher grade tires then the average tire cars are sold with. This is why it's no surprise to see some cars in game come with Sports Soft from the factory, they are not DOT competition level.

My opinion is Sports Soft are DOT Comp level, Sports Medium are on the line of high grade and DOT Comp, while Sports Hard are equal to the Highest a Grade tires sold on a car.

Lol, I think RH are a Track only tire with grip above DOT competitions, but I have nothing to show this beyond theoretical possibilities. If someone were to make that argument, what do we have as fact to show otherwise?

I thought since people had fixed ideas of SH to SS being comp level tires this would be based on comparing max grip of tires IRL vs GT, & that data would be available. The g-meter we see while driving being vague and showing constant spikes would of had to of been used on previous test, now that data logger can show clear sustained G's I would think it appropriate to revisit those comparisons.

Sustained G's with Sports Hard tires seems very comparable to some modern cars on the skid pad registering G's on factory tires.

Nobody already running these test already is a bit of a surprise.

Try this, try to replicate the lap time and then beat it. If you feel the tire is too grippy compared to the real life tire used, go lower to SM ( read the notes for detailed info )

Notes :
I built this replica upon request from a fellow member f1357924680, he asked for a different version of the FEED RX7

So, after research of the car competing in 2011 Tsukuba Superlap Battle, I used the Touge FEED RX7 version and make slight changes for this replica.

The FEED Fujita Engineering FD3S produces 450PS using FEED T04RS Turbo Kit. Basically the FEED R7 is a street car with excellent tune ups. Weighing at 1260kg and a perfect balance of 50/50, the RX7 proved it's potential in the hands of Nobuteru Taniguchi during December 2011 Tsukuba Superlap Battle in Street S-Class.
During the competition, as the car is in street class, it maintained almost everything, air conditioner, stereo, and still uses H shifter gearbox. The tires used was ADVAN A050 R Spec G/S ( soft ) Compound 295/35R18, the tire only lasted for 3 laps , and they have to be replaced, the equivalent in GT6 is sports soft tire.
The car won the battle with 58.051s lap. A few months later, March 2012 precisely, the car was taken to Tsukuba again for further testing while also attempting to break the previous record. The 58s time was done in the winter, with low temperature, while this time in March, the weather is suitable for the tires and the car. In the hands of Nobuteru Taniguchi, the FEED RX7 posted an incredible 57.511s lap time at Tsukuba in the same setup as in 2011 Tsukuba Superlap Battle.


Suspension comes from FEED PRO-F09 coilover damper kit, I set the spring at 15/15 as the real life value is not possible in GT6, with a fine tuned damper and ARB, the car gives exceptional response throughout the corner, with tuning aimed at ultimate balance.

LSD is 2 way from FEED, this time I tuned for Tsukuba, which means high preload and high locking rate. This gives the best possible traction and flexibility on the limit.

Gearing is stock, I have to correct this according to real life OEM 5 speed ratio. The FEED RX7 uses FEED 4.7 Final Gear for Tsukuba, which gives the car explosive acceleration that is essential at Tsukuba

I mainly tuned and tested the car at Tsukuba. It easily lap Tsukuba on sports soft at 58s.

Aim to replicate the real life lap time, either the 58.051s or 57.511s lap time. My best so far after a few laps is 57.2xxs

ENJOY

 

[Bobby Steel]

Lap times in game and IRL not so accurate in comparison for too many reasons to list. Grip levels are objective, measurable, comparable.

That is interesting

While Yes I knew already about the hidden tires, I was unaware of the possibility that they applied different sets to different cars. I seen it as tire options not available to any car (unless hybrided) and basically only represent a few steps jump going from one series to the next (Comfort to Sports for example) but apply the same steps.

Are you certain they applied hidden tires to cars in GT5 from factory? How so?

It would explain why the classic muscle have crap grip on the same tire vs a modern car on the same tires.

I would think though they possibly carried this over from GT5 so if a car got a crapier version Of the same tire grade it would be the same in GT6. IF they still have hidden tires.

 

[Mirado_7]

There was a post by some one that went out to a skip pad and tested all the tires somewhere around here laying all this out. All I remember from it is RS = fantasy tire with no real world counterpart, RM = Fomula1 softs, RH = Sports Car softs, SS = Sports car racing hards, and then SM and SH would be your typical track day tires for Joe everyman.

 

[Bobby Steel]

Now that's some data Id like to see and is due for re-test with data logger

100% certain. Anyone that hybrided will know this. And I haven't done any hybriding in GT6 but it certainly feels as if they've done the exact same thing in this version of the game.

FYI, referring to someone as "you" in an open forum isn't really specific enough. You should either quote the post in question then make your remarks or preface your remarks by saying, " @Bobby Steel do you think...blah blah blah"..so we know who you're talking to.

I spent much time hybriding, but it is not clear that hidden tires were used on cars from factory. This is why I ask how you draw that conclusion.

I started hybriding in HxD and got full car data files saved for reference. If it's in the car data coding just tell me where.

 

[SiNS3V3N]

If you look at the tires of more cars you will see different tread on S tires.

Those are the average tread most cars get but many have different tread patters

Yellowbird, old muscle cars, and the closest I've seen to those R888's are on the Camaro RS

They all have different grip levels. It appears grip and tread pattern go together.
