Expert Buying Guide for 2013 Ram 1500 Regular Cab
For your 2013 Ram 1500 Regular Cab, the 5x139.7 bolt pattern is shared across 2011–2018 models, ensuring cross-compatibility. However, the 77.8mm center bore is critical: aftermarket wheels often have a larger bore (e.g., 78.1mm or 83mm), requiring hub-centric rings to prevent vibrations and ensure load is on the hub, not the lug nuts. Offset is sensitive; the factory 19mm offset maintains proper geometry. Deviating more than ±10mm may cause rubbing or clearance issues. Always use the correct 9/16" lug nuts with the proper seat (cone or ball) matching the wheel's design. Never use incorrect thread pitch or seat type, as this can lead to wheel loss. Re-torque after 50–100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 130–140 ft-lbs after 50–100 miles, then periodically check.
- ✅ Aftermarket wheels often require hub-centric rings (77.8mm ID to wheel bore OD) to avoid vibrations.
- ✅ Verify offset: factory is 19mm; aftermarket offsets from 0 to +30mm typically fit, but test fitment for brake caliper clearance.
- ⚠️ Torque lugs in a star pattern to 140 ft-lbs (190 Nm), then re-check torque after 50-100 km (30-60 miles).

2013 Ram 1500 Regular Cab — Frequently Asked Questions
What is the bolt pattern for a 2013 Ram 1500 Regular Cab?
The 2013 Ram 1500 Regular Cab uses a 5x139.7 bolt pattern (also called lug pattern or PCD). The center bore is 77.8mm and the offset is 19mm.
What other years of Ram 1500 Regular Cab have the same bolt pattern as the 2013?
The Ram 1500 Regular Cab uses the 5x139.7 pattern from 2011 through 2018. Wheels from any of these model years are dimensionally compatible with the 2013, provided the offset and center bore also match.
What is the center bore of a 2013 Ram 1500 Regular Cab?
The factory center bore (hub bore) for the 2013 Ram 1500 Regular Cab is 77.8mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Why is matching the 77.8mm center bore important for the 2013 1500 Regular Cab?
The 77.8mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
Will wheels from another Ram fit my 2013 1500 Regular Cab?
Only if they share the exact same 5x139.7 bolt pattern, a compatible offset, and a center bore equal to or larger than 77.8mm.
What is the factory wheel offset for a 2013 Ram 1500 Regular Cab?
The OEM offset for the 2013 1500 Regular Cab is typically around 19mm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
