KXA400-New is a radial truck tyre designed for steer and trailer axles on trucks operating across mixed-surface routes, including paved highways, gravel feeder roads, construction sites, and quarry access roads.

What KXA400-New Is Built For
KXA400-New is a radial truck tyre designed for steer and trailer axles on trucks operating across mixed-surface routes, including paved highways, gravel feeder roads, construction sites, and quarry access roads. The tread pattern is engineered for consistent grip and stability under variable loads and terrain, with a thick sidewall to resist impacts and bruises from curbs, rocks, and uneven surfaces. Stone rejection grooves prevent aggregate from lodging in the tread base, reducing the risk of casing damage. The tyre carries M+S and 3PMSF markings, allowing year-round use in winter conditions without seasonal changeover. Four sizes are available, ranging from 385/65R22.5 to 425/65R22.5, with ply ratings from 18 to 24 and load indices up to 165.
Manufacturer Feature Claims
- Suitable for Trailer and Steer Axle of Trucks Under All Kinds of Working Conditions
- Thick sidewall design protects against sidewall impacts and bruises
- Stone rejection design protects groove bottom from stone puncture
- Lasting grip and stability,with M+S and 3PMSF marking
Key Benefits
- Thick sidewall construction resists impacts and bruises from curbs and unsealed surfaces
- Stone rejection design prevents trapped aggregate from damaging the casing beneath the tread
- M+S and 3PMSF markings allow legal use on winter routes without seasonal tyre change
- Four sizes from 385/65R22.5 to 425/65R22.5 cover most steer and trailer axle fitments on medium to heavy trucks
- Load index up to 165 supports 5150 kg single at 825 kPa on the 425/65R22.5 fitment
Problems It Solves
- Standard steer tyres fail prematurely on unsealed roads due to sidewall damage from impacts and bruises
- Stones trapped in tread grooves can work through to the casing, leading to early failure before tread wear
- Running separate summer and winter tyres for steer and trailer axles increases stock and fitting complexity
- Low sidewall strength in some radial tyres leads to casing loss on rough terrain despite adequate tread depth
- Lack of M+S or 3PMSF marking limits legal use in winter conditions, requiring seasonal replacement
Who It Is For
- Truck and trailer fleet operators needing steer and trailer tyres that survive mixed-surface duty
- Distributors supplying tyres to contractors and logistics companies in markets with poor road infrastructure
- Importers sourcing one container of mixed sizes and patterns for regional distribution
- Government and municipal transport departments buying tyres for mixed-terrain service vehicles
- Contractors requiring tyres with winter markings for compliance in regulated markets
Application Scenarios
- Truck fleets running daily between urban distribution hubs and rural construction sites with unsealed access roads
- Trailer axles on long-haul trucks that encounter gravel roads, construction zones, and highway segments
- Steer axles on regional haulers operating in mountainous or rural areas with poor road surfaces
- Fleets in regions with seasonal snow and ice that must maintain legal winter compliance year-round
- Contractors transporting materials across mixed terrain where tyre durability and traction are critical
Technical Features
- Radial casing construction with thick sidewall design for impact and bruise resistance
- Stone rejection profile in the groove bottom to eject trapped aggregate under deflection
- Tread pattern optimized for grip and stability across on-road and off-road conditions
- M+S and 3PMSF markings certified for severe snow service, meeting winter road legal requirements
- ETRTO norm tread depth across all listed sizes, with 18.0 mm for 385/65R22.5 and 18.5 mm for 425/65R22.5

Where This Pattern Wins and Where It Does Not
Compared With Standard highway steer tyres
KXA400-New has a thicker sidewall and stone rejection design, which improves durability on unsealed roads but may reduce rolling efficiency on paved routes
Compared With Dedicated off-road trailer tyres
A deep-lug off-road pattern offers better traction in mud but wears faster and runs noisier on paved roads; KXA400-New balances off-road resilience with on-road performance
Compared With Separate summer and winter steer tyres
The 3PMSF marking allows KXA400-New to replace both seasonal patterns, reducing stock and fitting complexity
Use Guide
- Match ply rating to your actual axle load, not to the heaviest tyre available - overspecifying increases cost and reduces ride comfort
- Check the standard rim listed against your wheel: 11.75 for 385/65R22.5, 12.25 for 425/65R22.5
- Inflate to the pressure shown for your load in the size table; dual and single fitment pressures differ
- Inspect groove bottoms for lodged stone after every off-road cycle to protect the casing for retreading
- Rotate steer and trailer positions before irregular wear sets in, especially on fleets with one-way loading patterns
KXA400-New Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ of 385/65R22.5 or 425/65R22.5 typically fills at container weight rather than volume, so the practical minimum is one container. Mixed loads across sizes and patterns are accepted.
What is the lead time?
It depends on whether the size is in stock at the plant or has to be produced. We confirm current availability with the plant at the time of quotation rather than quoting a standard figure.
Which sizes are available?
385/65R22.5 in 18, 20, and 24 PR; 425/65R22.5 in 20 PR. Full load index, rim and pressure data for each is in the size table on this page.
Is this tyre legal for winter use?
It carries both the M+S and the 3PMSF alpine markings, which is the marking most European winter regulations require. Confirm your own national rule before ordering.
Can you supply DOT or ECE marked tyres?
Marking requirements vary by destination. Tell us the import market and we confirm what marking the plant can supply on that size before you place the order.
What warranty do you give?
One year against manufacturing defect on all tyres we supply, with claims handled by us directly. Cargo transportation insurance is provided on the shipment itself.
Can you ship a mixed container with other patterns?
Yes. Most of our customers load one container across several patterns and sizes, which is the main reason to buy through us rather than from a single plant.
