Real Tire Physics. (aka Sport Sim Drift and Grip Tire Physics V5.1) I decided to rename them because that was becoming a mouthfull and this is done and a more appropriate name. I mean it's so done and real now that i even perfected the AI values for each tire and physic combination. I also added the .1 in grip i accidentally removed before my v5 release (the reason for the update) and fixed the tire heating/cooling to be more realistic. I also COMPLETELY REDID THE FFB MOD to be unbelieveably realistic feeling and leo's is no longer needed. Make sure you read the readme on that. I also added a code in the readme for very simple copy/paste edit style installation. Please copy this code into your selected cars upgrades.ini or add the 4 upgrade levels into an existing option for tire physics replacing the (size of your choice part) with either 15, 17, or 18... your choice for that car lol

So I lied I'm now at V5 of my physics and im positive this one is final now. I started from scratch and used all real world data and knowledge to build this version. See Readme for instructions. Basically choose which tire size and which physics model of it you want to use and either edit the hdv of the vehicle to call to it or open it and copy the data and paste it into that cars tires. V3.1 - V5 links will be available.
I reuploaded the link... I made a mistake cause I was uploading this in such a hurry yesterday and uploaded a alternate file with lower slip peaks for the super sport tires making it very hard to drift with lighter cars. If you d/l'd v3.1 yesterday or before this notice was posted please RE download it as your file is flawed. Sorry for the inconvienience.
V3.1 is FINAL VERSION I did some tweaks to make things feel a little more realistic... It's now realistic enough that I felt it important to include my FFB Mod with this so you can feel things properly. Please see all readme's for important installation instructions.
v5.0 I have started from scratch to make the best tires ive ever driven hands down. V4.0 I made several changes that affected the feel including the slip curve and added physics options. V3.0 I added several super sport tire options since v2.0 and completely redid the slip curves to be more accurate along with many other changes. This version may be TOO realistic and because of that I'm keeping the v2.0 link available since it is easier though less realistic.
To install this update I recommend you first extract the files to your rFactor\GameData\Vehicles folder. This way it will always be their to either be called on by an HDV file or to be a place holder to use to transfer it to multiple other mod or vehicle folders. You can simply modify the HDV file for each vehicle you wish to use it on by changing the line "TireBrand=" To call for my file if you do not wish to move or rename things. If you don't wish to modify HDV files for each vehicle you want to use my tire physics you must move and rename my file to replace the original one for that vehicle.You can also open the tire file of your choice with notepad and copy all of its contents then open the tire file you wish to replace and paste over all of its contents. Make sure you have a backup of the mods original tires prior to doing this however should you wish to go back to them.
Their are several choices of tire to choose from. Their are basically 4 different physics styles of 3 different sizes of tire. Sport 15 has a smaller diameter for cars like the ae86 and miata. Sport 17 is the standard size tire, sport 18 is for cars with slightly bigger wheels like soarer skyline etc. The standard one with no suffix is the normal set of physics your used to with most sim games/mods. Grip is the same in Normal, Simcade and Super Sim but what is changed is the way the tires feel to drive and the load character. Normal tires (arcade) have very high peak slip angles and less load fall off making them much slower to react and theirfore easier to control. Simcade is a happy balance of sim and arcade style, the peaks are only twice as high angle as they should be instead of three times higher like the arcades and the fall off is half way in between. The super sims and wet/ice have realistic peak angles and load character and are hard to drive. All 3 regular physics modes simulate dry and wet lat and long g values of the respective tires. The Wet/Ice physics convert all tracks into wet tracks and wet tracks into ice in super sim phyiscs mode. It can be quite fun if you can handle it =D
*NOTE: If you have the same file in multiple places it could cause a problem if you attempt to modify the file in one of the locations without changing all of them. I recomend not using the same file name in more than one place.
--------------------What the Update affects-------------------
These physics will ONLY AFFECT the tire physics and will not affect the individual car phsyics whatsoever. I am working on a update to fix all the drift cars physics also.
The used tires have about half their tread life left and are close to the wear indicators and have been sitting in a used tire shop for atleast a year making them very very hard compound and very low grip as a result. Both used tires will wear only slightly faster than a new tire as even though they are half worn they are harder compound and more resiliant to heat. TOUGE USE IS NOT RECOMMENDED, WILL HAVE VERY LITTLE GRIP IN WET CONDITIONS
The Continental's have softer sidewalls and flex alot more and have peak grip near the cold temperature and will lose alot of grip once overheated. They work well in the wet but are a master of none.
The Falken Ziex is a standard sports tire and has stiffer sidewalls and softer rubber giving more grip and higher heat tolerance but still provide good wet weather traction. These are the BEST tires for wet weather when new.
The rest of the tires are all popular super sports tires and have very stiff construction and very soft rubber with very little tread. They still work in wet weather. They also take alot of heat and wont grip as well untill they get up to working temperature typically in the 180-200 degree range. They all have subtle differences that can be felt but are generally very similar, some are better in grip than others and some are better in drift.
The differences in all the tires reflect those that were expressed in the manufacturers specifications as well as the results of tests performed on some web sites and many many reviews of those who have used several of the tires replicated.
*Note: I created these to replicate several different tire types. They are good for both grip and drift because I USED REALISTIC SLIP CURVES AND PEAK ANGLES!!!! Because of that it might take some getting used to if your using Super Sim physics or Wet/ice because they are so precise. Grip should feel natural and normal, but drifting will be much snappier than most drift mods original tires because of the realistic peak angles. I HIGHLY recommend you use the FFB update included in this It has a separate readme that must be followed to install properly. Also using high FOV will make drifting with low steering lock difficult because you cant see the angle as well and your reaction time is slowed. Using good head movement settings helps also. 100% lookahead if your using a wheel on a small screen is a must for example. Once you are accustomed to it you will realise that though it is difficult it is the most realistic drifting tire physics you will come across. You can ease into a floaty low angle drift or flick the car out to opposite lock with ease once you learn to balance the car sideways properly with proper tires. These tires are so realistic though that if a car your using my tires on has very unrealistic suspension or other values in the hdv are out of whack it might make drifting impossible. Or if it is a hard car to drift in real life you will find the same to be true if the car physics are accurate. Aasbo supra is a good realistic car to use and it's original tires feel almost as good as mine do to begin with.
ME!!! =P for wanting a true to life feeling set of tire physics and having too much spare time on my hands. LMAO
ISI for creating this AWESOME game
Tirerack.com for keeping so many records on tires.
Caranddriver.com for providing actuall grip data and direct same car compairison to most of the tires included.
Too many other websites to list that provided great knowledge on physics of real life tires.
All the moders who create the great mods to use my tires.
You may modify these files to your hearts content. This is a update I made for myself and thought I should share it with the community. Feel free to make them suite your needs and try them on any vehicle you wish.
