As my son (teen ti) stated earlier, 30-32 front, 35-36 rear, but that is for auto x, not sure if that translates to the track or not. Good luck with them. The RE-71r's have been working very well for us but we seem to be getting some funny wear on the center section of the tire. The outside edge of the center solid bar of the tire is wearing unevenly. almost like a beveled shape from low on the outside edge to normal on the inside edge. The rest of the tire is wearing pretty much evenly (considering 4 degrees camber and 1 degree toe out on each front wheel) Have not really been able to find out anything about it. I am thinking of taking the wheels to the shop and have them switch the tires to the opposite sides to even out the wear. Let us know how they perform. |
