Fortune FAR603 315/80R22.5
Best for: Buyers who want tread features that support wear monitoring and even wear. The listed shoulder-rib wear indicators can help identify alignment issues, while optimized rib width is described as promoting even wear.
The FAR603 has multi-angle grooves intended to improve tread rigidity and reduce rolling noise. Its Movematic sipes are described as closing as the tire rolls through the footprint, allowing tread blocks to interlock and stiffen. The listing gives a 75 mph L speed rating.
Why it was selected: It offers several specific tread and wear-related features in the requested size. Limitation: The supplied details do not identify it as a steer-position tire; confirm that application before purchase.
Ironman Gen 2 I-31M
Best for: Buyers who prioritize the listed traction design for wet and dry driving. The Ironman Gen 2 I-31M is sized 315/80R22.5 and has zig-zag biting grooves that the product information says enhance handling and traction during driving and braking.
The listing describes the tire for on- and off-road use and identifies it as load range L with a 20-ply rating. Those details make it a useful option to compare when the truck’s requirements call for that size and rating.
Why it was selected: Its listed groove design directly addresses traction and handling. Limitation: The listing does not confirm steer-axle suitability, so check the tire’s approved position and vehicle requirements.
Kumho KLS09 315/80R22.5
Best for: Buyers who want a tread design intended to reduce stone retention. The product details say the KLS09 uses grooves with varied angles to help prevent stones from holding in the tread.
The listing also says the design reduces tension in the shoulder and bead area. It identifies the size as 315/80R22.5, making it a candidate for shoppers comparing tires in this exact dimension.
Why it was selected: Its stated groove and shoulder features provide a clear point of comparison. Limitation: The available information does not provide a load range or confirm steer-axle approval; verify both for your application.
Ironman Gen 2 I-52A
Best for: Buyers comparing another Ironman tire in 315/80R22.5. The supplied listing identifies the I-52A as load range L with a 20-ply rating and names Ironman as the brand.
Why it was selected: It matches the requested size and gives shoppers a second model to check against the I-31M. However, the provided product details do not describe its tread pattern or performance characteristics, so compare the full specification before choosing between the two.
Limitation: The available features do not confirm steer-position use or explain the model’s intended operating conditions. Verify those details with the seller or manufacturer.
Falken RI151 315/80R22.5
Best for: Buyers who need to compare a stated dual-load figure. The listing identifies the Falken RI151 as 315/80R22.5, load range J with an 18-ply rating, and gives a maximum dual load of 7,390 pounds at 123 psi.
Why it was selected: The stated load information gives buyers a specific figure to check against axle requirements. Limitation: The provided details do not list a single-tire load figure or confirm steer-axle suitability. Do not use the dual-load figure as a substitute for checking the complete tire and vehicle specifications.
Buying Guide: How To Choose A 315/80R22.5 Steer Tire
Is the tire approved for steer-axle use?
Do not assume that a matching size makes a tire appropriate for the steer axle. Check the manufacturer’s application information and confirm the tire’s intended position with a qualified tire professional. The product details here do not establish steer approval for every model.
How should load and inflation be compared?
Match the tire’s load capacity and required inflation to the truck’s axle rating and operating conditions. Pay attention to whether a specification is for single or dual fitment. For example, the Falken listing gives a dual-load figure; that is not the same as a single-load figure.
Which tread features matter for your routes?
Compare the feature that addresses your operating concern. The Ironman I-31M lists grooves for wet and dry traction, the Kumho KLS09 emphasizes reduced stone holding, and the Fortune FAR603 lists wear indicators and even-wear features. These are stated product features, not a guarantee of results in every operating condition.
What else should buyers verify?
Confirm the exact size, load range, ply rating, speed rating, and application before ordering. Check that the tire matches the vehicle maker’s requirements and your fleet’s service conditions. If a listing omits an important specification, request it rather than inferring it from the model name.
