Smooth Move
Oh, wow. Imagine someone actually dedicating time and energy to use an orbital sander to remove the grooves on their car’s tires. We’ll admit that slick tires can come in handy on dry roads, which is why racers use them. However, they don’t manually sand down the treads of their tires to produce the silky smoothness that you see.
It’s smarter to leave the treads on than it is to remove them for a multitude of reasons. The most important of which is that it provides traction on both dry and wet roads. The OP obviously has no idea what traction is, and we hope someone corrected the problem before they hit the road.
