This Loadstar ST175/80D13 bias tire delivers a 1,360-lb maximum load at 50 psi and carries an M speed rating (81 mph). The 6-ply design gives it the strength needed for steady towing across long distances or frequent trips. Paired with a steel wheel rated at 1,660 lbs, it’s built to meet DOT specifications for confident highway use.
No extra mounting work required. The tire comes already mounted on a 13" x 4-1/2" galvanized steel wheel with a 5 on 4-1/2" bolt pattern and a pilot diameter of 3.19". It’s aired up and ready to install so you can skip the shop time and hit the road faster.
Moisture, salt, and humidity don’t stand a chance against the galvanized finish on this 8-spoke steel wheel. It’s made to stay corrosion-free season after season, whether stored outdoors or used around water. That means less worry about rust and more focus on keeping your trailer rolling.
The bias design uses thick nylon cords set at a 30- to 45-degree angle in alternating layers. This crisscross pattern stiffens the sidewalls so the whole tire flexes evenly, helping maintain stability and a smooth ride when towing over rough or uneven terrain.
If this tire is damaged within the first 12 months, it’s replaced at no charge under Kenda’s worry-free guarantee. Combined with a 5-year tire warranty and limited 2-year wheel warranty, that kind of coverage makes this combo a dependable long-term choice for everyday trailer use.
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"
