Expert Buying Guide for 1998 Cadillac Seville
For your 1998 Cadillac Seville, the bolt pattern is 5x115 with a 70.3mm center bore. When selecting aftermarket wheels, hub-centric rings are mandatory to ensure proper centering and prevent vibrations. The factory offset is 42mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify lug nut compatibility: the thread pitch is 12x1.5, and the factory uses a conical (60-degree) seat. Using incorrect lug nuts can lead to wheel loosening. Stick to wheels from 1992–2004 Seville models for guaranteed fitment.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to maintain clamping force.
- ✅ Avoid wheels with a center bore larger than 70.3mm without hub rings; smaller bores won't fit.
- ✅ Check for caliper clearance when using wheels with offset below 37mm or above 47mm.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
