It's not jsut the tyre is it? I know on my Hyper 7 RTR the wheels look a bit wonky... but it's actualy jsut the fact that the pre glued wheels aren't actualyl glued straight onto the rims... My guess is at high speed the wheels bulge up and the wonkyness is far more noticable.
I'm totally new to RC though so don't take my word for it !!
