So often on my builds I use the smallest tire size possible, I would think that it would have the least amount of drag right? Nope Any bigger than the base 1 is going to have less drag. I have actually seen the smallest tires create up to up to 400 points of drag while very large tires only around 100 to 150. This is very frustrating because I don't exactly feel like putting massive tires on my planes. This "Bug" has actually made some of my creations nearly unflyable. Also expanding the width tends to decrease drag.... I have no clue how making something larger causes less drag but I hope this will be changed in 1.8. Tell me what you think in the comments
