The result is that the tire will &#8220;go off&#8221; or begin to loose traction. Extremely low tire pressure (below 20 lbs) could cause sidewall damage.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li>TREAD DEPTH:\n<ul>\n<li>At <span style=\"text-decoration: underline;\">full tread-depth,<\/span> the inner two grooves of the TOYO RA-1 tires are 8\/32nds of an inch deep, and the outer 2 are 6\/32nds of an inch deep.\n<ul>\n<li>At full tread-depth the TOYO RA-1 is famous for it&#8217;s performance in the rain.\n<ul>\n<li>Rain pressures should be about 5 lbs lower than the &#8220;dry&#8221; starting pressure<\/li>\n<\/ul>\n<\/li>\n<li>At full tread-depth the TOYO RA-1 is an awesome performing street tire.<\/li>\n<\/ul>\n<\/li>\n<li>Shaving the tire eliminates what is called &#8220;tread squirm&#8221; and allows the tire to react quicker to driver input and vehicle directional changes.<\/li>\n<\/ul>\n<\/li>\n<li>DIRECTION AND ROTATION:\n<ul>\n<li>The tire rotation directions indicated on the sidewall of the tire are important for water drainage in rain or wet conditions.<\/li>\n<li>However, the direction of rotation can be changed to suit the driver&#8217;s needs once the tire has been shaved and\/or worn down. Thus, you may use the tire in any direction of rotation <span style=\"text-decoration: underline;\">when not in rain or wet conditions<\/span>.<\/li>\n<\/ul>\n<\/li>\n<li>TIRE DAMAGE:\n<ul>\n<li>The most common tire damage is when the tire\/wheel combination strikes the edge of a pot hole, a curb at the side of the track, or the edge of the pavement. If the driver should drop a wheel over the edge of the track and the track&#8217;s edge is higher than that of the pavement, the sudden sharp impact could cause the bead area of the tire to become broken. Should this happen, a bubble will appear on the sidewall of the tire.
