The next vehicle that will be added to the game will be a tractor. There are some things that need to be fixed and fine tuned, but the plan is to release it this week probably in the weekend. In tractors the tires have a significant contribution to the suspension, some relying exclusively on the tires for suspension. Using soft body physics tires will help with achieving a simulation closer to the reality. There are plans to add more tractors to the game in the near future.
