Howo Mining Truck Tire Specs | 16.00R25 OTR Tire Size
Core conclusion: The 16.00R25 is the factory standard tire for Howo off-highway dump trucks of 105/110/120 tonne classes; models of 70-tonne, 90-tonne and 135-tonne are not factory-fitted with this tire size.
1. Tire Configuration List for Full Range of Howo Mining Trucks (Sinotruk Official)
Mining Truck Model | Rated Load | Factory Tire Configuration | Rim | Remarks |

Howo 90t Mining Truck | 90 t | Front: 14.00R25; Rear: 14.00-25 | 10.00/10.5-25 | Small open-pit mines |
Howo 105t Mining Truck | 105 t | 16.00R25 (All-steel radial OTR tire) | 11.25-25 | Standard fitment, 6×4 drive, 35/38 m³ bed |
Howo 110t Mining Truck | 110 t | 16.00R25 | 11.25-25 | Medium open-pit iron ore, earth & rock stripping |
Howo 120t Mining Truck | 120 t | 16.00R25 | 11.25-25 | Medium open-pit coal mine, 42 m³ bed |
Howo 135t Large Mining Truck | 135 t | 16.00R29 | 11.25-29 | Heavy-duty large tonnage, larger than 16.00R25 |
Tire quantity: All Howo mining trucks adopt 6×4 layout, 10 working tires + 1 spare tire (10+1)
2. Detailed Specification Interpretation of 16.00R25 (OTR Radial Mining Tire)
16.00: Tire section width 16 inches ≈406 mm
R = Radial, radial construction with steel belt
25: Nominal rim diameter 25 inches
Key Parameters of 16.00R25 Mining Tire (Common L3/E3 Mining Tread Pattern)
Standard rim: 11.25-25
Overall diameter at rated inflation: approx. 1535 mm
Section width at rated inflation: approx. 440 mm
Ply rating: ★★★ reinforced mining grade, generally 40PR
Maximum single tire load capacity: 8000 kg (under rated cold inflation pressure)
Recommended cold inflation pressure: 600~800 kPa (adjust according to load; use upper limit for heavy load uphill)
Tread depth: 40~45 mm, deep block pattern, good cut resistance and chunking resistance
Type: TL (Tubeless) / TT (Tubed) versions. Tubed type is widely used in mining sites.
Difference between radial 16.00R25 and bias 16.00-25
16.00R25: Radial tire. Better heat dissipation, higher wear resistance and load capacity, higher price. Factory standard for new medium & large Howo mining trucks.
16.00\\-**25: Bias tire with nylon carcass. Poor heat dissipation, prone to heat build-up and blowout. Used on older models, rarely factory fitted nowadays.
3. Selection & Replacement Notes (Common on Site)
Howo 105/110/120 tonne mining trucks are delivered with 16.00R25 as original fitment, direct matching.
70-tonne and 90-tonne models are not originally equipped with 16.00R25. Direct upgrade to 16.00R25 is not recommended: interference may occur with wheel arch, suspension, axle housing and rim mounting space.
- Multiple tread patterns available for 16.00R25:
L3: Crushed rock & gravel quarries, prioritizing cut resistance
E3: Earthworks & coal mines, prioritizing wear resistance
Different brands (Triangle, Fengshen, Guizhou Tire, Linglong OTR) have slight differences in load capacity. Confirm load index and star rating before procurement.
Mine-site modification: Some operators retrofit 70/90t trucks to 16.00R25. Rim replacement is mandatory, and check wheel cover clearance & steering interference.
4. Common Misconceptions
❌ All Howo mining trucks use 16.00R25: Only 105~120 tonne models come with this size as standard.
❌ 16.00R25 and 16.00-25 are interchangeable: Different construction, load rating and heat performance; cannot be mixed.
❌ Higher inflation pressure is always better for radial mining tires: Over-inflation is forbidden. Excessive heat under heavy downhill load may cause carcass separation.
