When you’re running long miles at highway speed, this tire is made to stay cool and steady. The Karrier ST205/75R14 Radial Trailer Tire (Load Range C) carries up to 1,925 lbs at 60 psi and is speed rated M (81 mph). It meets Department of Transportation specs and uses radial construction that keeps rolling resistance low for smooth, stable handling mile after mile.
The tread design makes a big difference on wear and feel. This one uses a 5-rib pattern that spreads the load evenly across the tire to minimize cupping and promote long tread life. Silica in the compound and angled sipes help it hold traction in wet conditions while resisting hydroplaning. The result is quiet, predictable performance whether the pavement’s dry or soaked.
The carcass is built specifically for trailer duty, not repurposed from passenger designs. Reinforced sidewalls keep the profile stable with heavy cargo on board, and the 6-ply rating under Load Range C gives the structure needed to handle real hauling weight without excess flex. It’s a sturdy setup that inspires confidence when you’re loaded down.
This KR35-type radial is tuned for reliable grip across different surfaces and weather conditions. The radial cord layout—set at a 90-degree angle to travel—lets the tire flex naturally without cords rubbing together, which cuts down heat buildup and extends tread life. It tracks straight on pavement but also handles off-pavement stretches with sure footing through rain or dry dust.
Stuff happens on the road, but this tire comes backed by a 1-year worry-free guarantee. If it’s damaged in any way within the first 12 months, it’ll be replaced at no charge. That kind of coverage adds real assurance to an already solid tire built for consistent performance season after season.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"
