Built for serious towing, the Karrier ST185/80R13 Radial Trailer Tire with 13" Aluminum Wheel keeps its cool on long hauls. The 8-ply, Load Range D tire carries up to 1,710 lbs at 65 psi and is rated for 81 mph (speed rating M). Double steel belts and full nylon plies help it stay stable and run cooler at highway speeds, giving you dependable performance when you’re loaded down and covering real miles.
This combo pairs the Kenda Karrier tire with a 13" x 4-1/2" aluminum wheel that’s made to fight corrosion. The gunmetal gray finish looks sharp, while the clear coat on both sides protects against scuffs, scratches, and salt exposure. It’s rustproof, lightweight, and strong enough for a wheel capacity of 1,740 lbs—an ideal match for anyone who wants durability without giving up a clean look.
No need to schedule a mounting appointment. The tire arrives already mounted on the wheel so you can bolt it on and hit the road right away. The wheel’s steel inserts in the lug nut wells keep everything tight by preventing wear around the holes, meaning you won’t be constantly checking for loose nuts after a few trips.
Radial ply construction keeps this setup rolling smooth on pavement. The cords sit at a 90-degree angle to travel direction to cut rolling resistance and heat buildup. That means better tread life, improved steering response, and traction that feels planted in wet or dry conditions—exactly what you want when towing at speed on busy highways.
Kenda covers this assembly with a 1-year worry-free guarantee that replaces the tire if it’s damaged within the first year, plus a 2-year limited warranty overall. It’s solid peace of mind knowing your investment is protected from day one.
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"

New tires and wheels look fantastic Robert! I passed along your review to Adam as well. What body of water do you mainly get your boat out on? We are located in Missouri, you can catch me at the Lake of the Ozarks or Mark Twain Lake chasing that 10 pound bass =)
