When winter weather hits, the right tire setup can make all the difference for your kei truck.
Snow, slush, black ice, and freezing rain transform even familiar roads into unpredictable challenges. For kei truck owners who use their vehicles year-round—whether for farm work, deliveries, or daily driving—studless winter tires are not optional.
In this guide, we’ll look at two of the most reliable studless tire options designed for kei truck and compact vehicle use: the Gripmax ICE X and the Gripmax ICE X SUV.

Why Studless Tires Matter for Kei Trucks
Kei trucks are lightweight by design, which gives them excellent maneuverability—but also makes them more sensitive to road surface conditions. In winter, that lightweight character can work against you:
- Less weight = less downforce on icy surfaces
- Smaller tire footprint = less contact area for grip
- Compact wheelbase = more sensitive to sliding
The right studless tire compensates for these characteristics, providing the grip and stability needed for safe winter driving.
Key Benefits of Modern Studless Tires
- Strong traction on snow-covered roads
- Reliable braking on ice
- Better water drainage during slush conditions
- Quieter operation than studded tires
- Legal in all U.S. states (unlike studded tires in some regions)
Gripmax: A Brand Built for Real-World Winter Performance
Gripmax has earned a reputation for producing high-quality tires engineered specifically for cold-weather and off-road conditions.
Unlike all-season tires that compromise across seasons, Gripmax focuses on purpose-built designs—meaning their winter tires are optimized for one job: gripping snow and ice when it matters most.
For kei truck and small-vehicle owners in cold-climate U.S. states (Colorado, Montana, Minnesota, Vermont, Maine, etc.), Gripmax offers two strong studless options worth considering.
Gripmax ICE X: All-Around Studless Performance
The Gripmax ICE X is built to handle a wide range of winter conditions, making it a strong all-around choice for kei trucks used in mixed cold-weather environments.
Key Design Features
- Asymmetrical tread pattern engineered for snow-covered roads
- Variable inner/outer tread sections to boost winter traction
- Zigzag edge design improves water evacuation and snow clearing
- Optimized rubber compound for flexibility in freezing temperatures
Real-World Performance
The asymmetrical design is the key advantage. The inner and outer sections of the tread are tuned for different jobs:
- Inner tread: Maximizes snow grip and slush displacement
- Outer tread: Provides cornering stability and dry-road handling
- Zigzag edges: Help clear snow from the contact patch on the move
The result is better grip and more stable cold-weather performance when conditions change unpredictably—exactly the situation kei truck owners face most often.
Best For
- Daily winter driving
- Light-duty farm and delivery work
- Mixed snow and dry road conditions
- Kei trucks used in moderate winter climates
Gripmax ICE X SUV: Designed for Tougher Conditions
The Gripmax ICE X SUV is built for drivers who need stronger performance in more demanding winter conditions—deep snow, frequent ice, rough rural roads, and heavier load use.
Key Design Features
- Four wide longitudinal grooves for snow and water evacuation
- Multiple directional grooves create additional biting edges
- Enhanced handling and braking performance under load
- Reinforced sidewall structure for rougher terrain
Real-World Performance
The wide longitudinal grooves are designed to expel snow and water aggressively, preventing the kind of buildup that causes hydroplaning and slush slip. The directional grooves create multiple “biting edges” that grab onto ice and packed snow surfaces.
For kei trucks used in heavier work—hauling firewood, plowing small lots, accessing snowy fields, or operating in mountainous regions—the ICE X SUV provides a noticeable upgrade in confidence.
Best For
- Heavy-duty winter use
- Snowy or icy rural routes
- Lifted kei trucks and overland builds
- Farms and properties with rough access roads
- Cold-climate states with extended winter seasons
ICE X vs. ICE X SUV: Quick Comparison
| Feature | ICE X | ICE X SUV |
|---|---|---|
| Tread Pattern | Asymmetrical | Wide longitudinal grooves |
| Best Use | Daily driving, mixed conditions | Heavy-duty, rough conditions |
| Snow Grip | Strong | Stronger |
| Ice Grip | Strong | Stronger (more biting edges) |
| Load Capacity | Standard kei truck use | Enhanced for heavier loads |
| Terrain | Roads, light off-road | Rough roads, rural use, lifted builds |
Style Options: White Letter vs. Black Sidewall
Both ICE X models are available in two sidewall styles, giving owners a choice between a bold off-road aesthetic and a cleaner, more understated look.
White Letter
- Aggressive, classic off-road look
- Stands out against dark wheels and lifted setups
- Popular for visual builds and show-quality trucks
Black Sidewall
- Clean, minimal, understated
- Blends naturally with any wheel finish
- Preferred for daily drivers and work-focused builds
Both versions offer identical performance—the choice is purely visual.

How to Choose the Right Winter Tire for Your Kei Truck
Picking between ICE X and ICE X SUV depends on three main factors:
1. Your Climate
| Climate Type | Recommended |
|---|---|
| Mild winters (occasional snow, light ice) | ICE X |
| Moderate winters (regular snow, frequent ice) | ICE X |
| Heavy winters (deep snow, extended freeze) | ICE X SUV |
| Mountain or rural cold climates | ICE X SUV |
2. Your Driving Style
- Mostly road use, daily commuting → ICE X
- Mixed road + farm/rough use → ICE X SUV
- Lifted or overland builds → ICE X SUV
3. Your Load
- Standard kei truck use (light cargo) → ICE X
- Heavier loads (firewood, equipment, cargo) → ICE X SUV
Installation Tips
Once you’ve chosen your tires, keep these tips in mind:
- Install all four tires at the same time — never mix winter and non-winter tires
- Check tire pressure weekly — cold weather reduces pressure significantly
- Break in new tires gradually during the first 100 miles
- Store summer tires properly — cool, dry, out of direct sunlight
- Inspect tread depth regularly — replace when depth falls below 4mm for winter use

Frequently Asked Questions
Q1. Are Gripmax winter tires legal in all U.S. states? Yes. Gripmax ICE X and ICE X SUV are studless tires, which are legal in all 50 U.S. states. Studded tires, by contrast, are restricted or banned in some states.
Q2. How long do studless winter tires last on a kei truck? Most studless tires last 3–5 winter seasons depending on use, climate, and road conditions. Because kei trucks are lightweight, tires often last longer than on full-size trucks.
Q3. Can I use winter tires year-round? It’s not recommended. Winter tire compounds wear faster in warm weather and lose grip on hot, dry pavement. Switch back to all-season or summer tires when temperatures consistently stay above 45°F.
Q4. What size winter tires fit kei trucks? Most kei trucks use 12-inch or 13-inch tires from the factory. Lifted builds may use 14–17 inch sizes. Always check the load index and speed rating before purchasing.
Q5. Where can I buy Gripmax tires in the U.S.? Gripmax tires are imported through specialty JDM parts dealers and tire shops. Availability and pricing vary by region. Many U.S. kei truck owners also order through Japanese exporters.
