Master the Curbs in Forza Motorsport with Improved Tire Physics
We’ve already told you that the physics leap in Forza Motorsport is bigger than Forza Motorsport 5, 6 and 7 combined. This 48x improvement in tire fidelity results in a more fun and rewarding driving experience with how the car accelerates, corners, and brakes. 
Previous Forza Motorsport games had only a single point of tire contact on the surface that moved at 60 cycles per second. This was problematic for curbs and rumble strips which could cause inconsistencies and unrealistic changes in suspension forces. This could also lead to tires briefly losing contact with the ground as they rolled over bumps resulting in unrealistic loss of traction.
Our new tire physics has 8 points of contact with the track surface running at 360 cycles per second. This allows tires to find grip on any type of uneven surface. The result is better drivability everywhere and realistic behavior on uneven surfaces like curbs.
Choose Your Tire Compound
Forza Motorsport features a variety of tire compounds to support great racing and different types of competition across several decades of production cars and race cars. 
Production cars will have the option to use Street, Performance, Race, or Drag tires along with the Wet tire. The Race tire is further broken into three separate compounds – Soft, Medium, and Hard. Each compound has different grip and wear characteristics. The Soft compound has the most grip, but wear out the fastest making it ideal for a Qualifying tire. The Hard compound has the least grip, but lasts the longest making it ideal for longer stints without having to pit for new tires.
There is also a Vintage tire that is used for classic cars, but it is not a selectable tire for other cars. 
We’ve also dialed in the tire heat model. The biggest change is in the grip fall off at extreme tire temperatures. There is a much smoother fall off as tires reach higher temperatures, which allows for better drivability and predictability even when you are overdriving your tires.
