Expert Buying Guide for 1998 Toyota T100 Xtracab
For the 1998 Toyota T100 Xtracab, the 6x139.7 bolt pattern is shared with 1995-1998 models. The 106.1mm center bore requires hub-centric rings for aftermarket wheels to prevent vibration and ensure load support. Offset must stay within 10-25mm; deviations risk rubbing or poor handling. Always use M12x1.5 lug nuts with the correct seat type (conical or ball) matching the wheel. Improper lug nuts can cause wheel detachment. Verify wheel weight rating exceeds vehicle GVWR. Re-torque after 50-100 miles.
