Hey guys I just got a new set of 15x8 drag stars with MT Et street bias ply 28x11.5-15's. Bought the tires through discount and discount doesn't seem to be comfortable mounting them without tubes because the tires say tube style. I have heard its better to run these with out tubes, is this true? I did some researching on MT's website and it looks like I should be running tubes especially with the mustangs weight.
