When you’re towing long distances, you want a tire that won’t flinch under load. This Loadstar ST175/80D13 bias tire delivers a 1,360-lb maximum load at 50 psi and carries an M speed rating of 81 mph. It’s built for trailers, not passenger vehicles, and meets Department of Transportation specifications so you can stay steady and legal at highway speeds.
This tire’s 6-ply rating uses thick nylon cords set at a 30- to 45-degree angle that crisscross through the sidewall. The result is a stiffer build that helps the entire tire flex evenly over dips or uneven ground. It’s that bias-ply strength that gives a smoother, more stable ride when loaded down, whether on farm roads or rough pavement.
The 13" diameter x 4-1/2" wide Dexstar-made steel wheel resists rust with its e-coat primer and durable white powder coat finish. The classic 8-spoke design looks clean while sealing out moisture and grime season after season. With a 4 on 4 bolt pattern, 2.65" pilot diameter, and zero offset, it’s straightforward to mount and built to stay looking good.
Skip the extra steps—this combo arrives as a complete tire-and-wheel assembly that’s tested to meet all DOT requirements. Rim dimensions are already matched to the ST175/80D13 tire’s section width of 6.6" and outer diameter of 24", so fitment and balance are dialed in from the start. Backed by Kenda’s 5-year tire warranty and a limited 1-year wheel warranty, plus a 1-year worry-free replacement guarantee if the tire is damaged in the first year, it’s a setup made for real use right out of the box.
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"

I loaded my zx14r ninja on this trailer and drove it from Florida to Michigan and back to Florida with no issues. It was awesome.

Its a year later and these tires are still going strong. Multiple camping trips with the now lifted popup under our belt and these tires have made pulling the trailer at highway speeds a breeze. The larger diameter combined with the axle lift also means getting the trailer into the back country is easier. Highly recommend these tires if youre doing a lift on your popup!

Tires are still doing well after their second 2500 mile trip. In my application they are not loaded to max, but are inflated just under maximum inflation. They have been running at speeds up to 75 mph without adverse effect.

Glad to hear you are liking them so far, Chase! Kenda makes very good tires and I'm sure they will work very well for you! ^___^ What kind of camper is that in your picture?
