The Kenda K353 Bias Trailer Tire – 5.30-12 – Load Range D is built for serious hauling. With its 8-ply rating and maximum load of 1,250 lbs at 105 psi, this tire gives you a sturdy margin when towing. It’s been rigorously tested to exceed Department of Transportation standards, so it’s ready for real-world trips where strength and reliability count.
Rated for highway speeds up to 65 mph, the K353 keeps steady on long runs without overheating or squirming under load. It’s designed to hold its shape and maintain traction across varied terrain, delivering confidence whether you’re cruising on smooth pavement or hitting rougher backroads.
The Kenda’s bias construction uses durable nylon cords positioned at a 30- to 45-degree angle in alternating layers. That crisscross pattern stiffens the sidewalls so the entire tire flexes evenly, giving you stable handling and a smoother feel on uneven surfaces. It’s a simple, proven design that performs when the trail gets bumpy.
This tire comes with Kenda’s 5-year limited warranty and a unique 1-year worry-free guarantee—if it’s damaged within the first year, it’ll be replaced at no charge. That kind of coverage means you can put real miles on it knowing you’ve got solid support behind every trip.
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"

Hey David. I can understand where you are coming from, they don't look right. When it comes to bias ply tires this is actually really common because of the way they are made. I have linked a video that talks about this if you would like to take a look at it.

The wheels should take shape fine after they are seated on a wheel.

Patrick I am just now getting to use them up here in Colorado. I pulled frm Texas up here with no problems. I am very pleased. As we speak I am in Ridgeway, Co with the camper. Thanks for the follow up. There are few vendors that follow up on their products after a year. Hats off to you and your company. Etrailer has always served me well. God bless you and Im praying you have a wonderful day.

I had the tires mounted last year before any camping was done. My first trip was about 250 miles each way and they held up well. The second trip was about 400 miles each way and they still did well. I was pleased with my purchase. Even the date of manufacture on the tire was only a couple of months old, so I knew they were fresh tires.
