Tires Front and Rear

Aft View New Tire & Shocks-1.jpg (43789 bytes)

145 or 155 SR 13 Radial (*Recommend Michelin 155SR13 XW4 Black wall, this is a symmetrical tire)

Note: 145 is the width in millimeters - 13 is the rim size in inches Make sure the tire is symmetrical in tread design.  The 155 width is the maximum size that will fit without spacing out the rear sprocket and creating chain alignment problems.

Tire Pressure ~ 30 to 35 PSI
I recommend using 35 PSI on the rear tire if you have the reverse unit.
Note: Running a low tire pressure on the rear tire will allow the reverse unit to spin against the tire.

Out-rigger tires

OutRigger Wheel-2.jpg (80575 bytes)

4.80x8 - Use a high quality 2 or 4 ply tire rated for Highway speed *Recommend Carlisle Brand
Note: Balance tires to provide for a smooth ride and to prevent repeated excess wear in one spot of the tire.  An unbalanced outrigger tire will rotate to the same position during its rest position (no road contact). Each contact with the road will then create excessive wear in one spot on the tire.  Run the tire  pressure between 10 to 20 PSI for increased tire wear and a smoother ride. The low tire pressure allows the sidewalls to flex thus reducing the scuffing effect/wear.
Note: Running a low tire may require tubes in the tires to prevent the tire from popping off the rim. (I prefer using tubes)
You can purchase a tire and rim together at Wal-Mart for $26.00.  This is a cheap tire and will not give you long mileage.
