This combo is made for serious road time. The ST205/75R15 radial tire is rated Load Range C, carrying up to 1,820 lbs at 50 psi with a speed rating of 81 mph (M). The matching 15" x 5" steel wheel is rated for 2,160 lbs, so both parts have solid capacity and meet DOT standards. The radial construction with double steel belts, double polyester cords, and nylon tread-firming overlays keeps heat down and tread life long on high-speed runs.
Corrosion doesn’t stand a chance against this finish. The modular steel wheel gets a zinc phosphate pre-treatment, an e-coat primer, and then a silver acrylic enamel layer that resists chips better than powder coat. This finish held up for more than 1,000 hours in salt spray tests, so it stays looking clean and resists road damage through plenty of seasons on the road.
This setup rolls out ready for smooth performance. Each tire-and-wheel assembly is match mounted and balanced using laser-guided equipment that aligns the lightest part of the tire with the heaviest part of the wheel, then fine-tunes with weights for an even spin. That balance means less vibration and wear from day one, no extra shop trip required before hitting the road.
Traction stays solid whether the pavement’s dry or slick. The automotive-grade tread uses ribs with breaks and cut sipes that channel water away from the tread surface instead of trapping it. The result is better contact with the road and confident control in wet, snowy, or icy conditions—all while maintaining stable highway handling that radials are known for.
Frequent tightening isn’t needed thanks to ITR technology built into the wheel design. A raised center disc with beveled, uncoated stud holes improves clamp force retention so the wheel stays snug against the hub over time. It’s a small detail that makes a big difference in keeping your setup solid mile after mile.
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"

Still holding up as expected. We put a lot of miles on our 6x10 cargo trailer, single axle. Ill wear these out before they dry rot or time out. Seems like a very fair deal, will do it again on my new trailer.
