| SR / SR5 (16") | P245/75R16 | 109 | S | 30 psi |
| TRD Sport (17") | P265/65R17 | 110 | T | 29 psi |

💡 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.

- LT265/70R17

📈 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: 285/70R17 fits TRD Off-Road with minimal rub at full lock
- Plus 2: 265/60R18 to 275/55R20 on Limited keeps OD within tolerance
⚠ 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 | 6x139.7mm (6x5.5) |
| Offset | +25mm to +30mm |
| Center Bore | 106.1mm |
| Common Widths | 7.0J–8.0J |
Hub-centric rings are required if your aftermarket wheel has a larger center bore than 106.1mm. Lug-centric mounting causes vibration and uneven wear.
❓ Frequently Asked Questions
What is the stock tire size on a 2020 Toyota Tacoma?
The factory tire size on a 2020 Toyota Tacoma varies by trim. Base trims use P245/75R16, while higher trims may run up to P265/60R18. Check your door-jamb sticker for the exact size on your vehicle.
Can I put bigger tires on my 2020 Toyota Tacoma without a lift?
Yes, within reason. Most 2020 Toyota Tacoma trims accept one size larger without rubbing, especially if you stick close to stock overall diameter. Plus 1: 285/70R17 fits TRD Off-Road with minimal rub at full lock
What is the bolt pattern on a 2020 Toyota Tacoma?
6x139.7mm (6x5.5). This determines what aftermarket wheels physically bolt up. Center bore is 106.1mm, which matters for centering the wheel on the hub.
What tire pressure should I run in my 2020 Toyota Tacoma?
The recommended cold inflation pressure is on the door-jamb sticker, usually 30 psi for most trims of the 2020 Toyota Tacoma. Check pressures cold (before driving) once a month.
Do I need to match speed rating exactly?
You should at minimum match the speed rating your manufacturer specified. Going to a lower speed rating can void some tire warranties and is not recommended for highway driving, especially on heavier vehicles.
Can I run all-terrain tires on a 2020 Toyota Tacoma?
Yes. Many 2020 Toyota Tacoma owners run all-terrains in OEM or one-size-up dimensions. Just confirm the load index meets the door-jamb spec and add a few psi if you go to LT-rated tires from P-metric.
