Better Tire Grip (ØnYx): realistic wet grip for American Truck Simulator

ØnYx adds wet grip parameters to every SCS tire so rain and snow don't turn ATS into an ice rink. In July the author confirmed it works on 1.60.

Author: ØnYx Compatible: ATS 1.60 (the author in the comments, July 18, 2026: "Yes, no changes have been made by SCS"; updated for 1.59 on May 6, 2026) Updated: 5 May 2026 Reviewed: 27 Oct 2026

What this mod does

Better Tire Grip is a physics mod by ØnYx that improves the wet grip of every SCS tire in American Truck Simulator. It has over 22,000 subscribers.

Why it’s needed

The author explains that, after the latest updates, rain and snow were far too slippery. SCS added the tire physics logic to ATS without adding its parameters, so almost every tire used default values. With the mod, tires behave consistently in the rain, with slightly less traction than in the dry and without losing control.

Tires covered

  • All stock ATS tires.
  • Those from the Wheel Tuning Pack, Goodyear Tires Pack and Michelin Fan Pack.

Values it adds

Standard front and dual rear: rolling resistance 4.5 and wet grip 1.3. Wide front: 7.5 and 1.35, with a bit more grip but much more resistance. Single rear: 5.25 and 0.975; the author recommends avoiding it.

Version

In May 2026 the author updated it for 1.59. In July, when asked about 1.60, he replied that it does work because SCS hadn’t changed anything. There’s no confirmation for 1.61. It’s about 68 KB.
