This idea is super simple, but would be pretty neat! For being an aircraft based game, you would think this would have been done already, but there aren't any tires specifically for aircraft. A traditional tread used on aircraft tires are vertical strips on the tire. I'm not sure what they are called, but regular car or tractor tires use intertwined crossed treads. But aircraft tires use treads that run vertically with the tire
Its a very simple yet useful addition that would make your aircraft look ever better!
