Best For
The Track Day Hauler
You're pulling an open or enclosed trailer to the circuit 8 to 12 weekends a year and reliability is non-negotiable. The K399's stiff sidewalls handle paddock curb strikes and gravel lots without drama, and consistent wear means you're not babysitting tread depth mid-season.
Perfect Match
The Cross-Country Tourer
You log serious highway miles with a loaded trailer across varied conditions. The K399's low rolling resistance keeps fuel costs in check and its heat-dissipating tread handles long interstate stretches without the thermal buildup that kills lesser trailer tires.
Great Match
The Heavy-Load Commercial User
If you're running a commercial hauling setup or consistently towing at or near maximum capacity, the K399's 6PR rating handles a solid range — but extreme-duty cycles with elevated tongue weights may call for a dedicated heavy-duty commercial trailer tire with reinforced sidewall construction.

Frequently Asked
Ply rating is shorthand for load capacity. The 4PR suits lighter trailers with modest tongue weight, while the 6PR handles heavier setups with more cargo. Start with your trailer's GVWR placard — that number tells you which rating you actually need. Over-speccing is wasted money; under-speccing is a blowout waiting to happen.
Hard no. Mixing load ratings on the same axle creates uneven load distribution and introduces unpredictable handling under stress. Both tires on an axle must match in size, load rating, and inflation pressure. The risk of premature failure and blowout is real — don't cut corners here.
Bias tires like the K399 deliver stiffer sidewalls that hold up better under load flex and resist punctures from road debris — both common trailer-use scenarios. Radials ride smoother and roll with less resistance, but they're more susceptible to sidewall damage and cost more. For motorcycle trailer duty, bias construction is usually the smarter, more pragmatic call.
Run the pressure stamped on the tire sidewall — trailer tires typically require maximum rated pressure regardless of how light your load is, which is the opposite of how you'd think about car tires. Low pressure is the leading cause of heat buildup and sudden failure on trailer tires. Check cold pressure before every trip, no exceptions.
Tread depth isn't the only clock running on trailer tires — UV exposure and ozone degrade rubber even when the tire looks fine. Plan to replace after 5 to 7 years regardless of remaining tread. Under proper inflation and occasional rotation, expect 8,000 to 12,000 miles of real-world service life in typical hauling use.
It's not mandatory under 55 mph, but if you're regularly pulling at highway speeds of 65 mph or more, balancing is worth doing. You won't feel the vibration the way you would in a vehicle, but unbalanced trailer tires quietly accelerate bearing and hub wear over time. At MTC we can handle balancing when you bring your trailer wheels in — call (714) 516-9059 to set it up.
