What exactly is wrong with the new one? I find it much easier to find the wheels I am looking for that I'm sure will keep the current tires, and the only issue is that a few mod cars spawn without tires now, no big deal, just put the tires on manually after spawning. If you have any other issues then it's probably either conflicting mods or something else. The only change I don't really get is how they made the biggest drag tires even bigger and they no longer fit in the wheel wells of my custom configs lol
What exactly is "the wheel code"? We fixed wrong tire sizes and stuff, the wheel generation code didn't really change?
How the wheels and tires are now is much better compared to 0.19. They are also somewhat easier to use for future mods. If you're just complaining about broken configs, just fix the few you use the most.
