💡 Reading the sizeExample: 275/65R18 116T. 275 = width in mm. 65 = sidewall as % of width. R18 = 18 inch wheel. 116 = load index (2756 lb per tire). T = speed rating (118 mph max).
🔁 Alternate Sizes That Fit
These sizes maintain stock revs-per-mile within roughly 3% (the threshold where speedometer, ABS, and traction control stay accurate). Always verify load index meets or exceeds OEM.

- 255/75R17
- 265/70R17
- LT285/70R17
- 255/70R18
📈 Plus-Sizing Options
Plus sizing increases wheel diameter while keeping overall tire diameter the same. This preserves your speedometer accuracy and gearing but allows wider tread and a more aggressive look.
- Plus 1: 33x12.50R17 (~285/75R17) fits Rubicon without lift
- Plus 2: 35" tires need 2.5"+ lift and bumpstop spacers
⚠ Watch the load indexIf you go below OEM load index, especially on trucks and SUVs, you risk a sidewall failure under load. Never drop more than 1–2 load index points from stock.
🔩 Wheel Specifications
| Bolt Pattern | 5x127mm (5x5) |
| Offset | +44mm (Sport) / +12mm (Rubicon) |
| Center Bore | 71.5mm |
| Common Widths | 7.5J–8.0J |
Hub-centric rings are required if your aftermarket wheel has a larger center bore than 71.5mm. Lug-centric mounting causes vibration and uneven wear.
