This combo is made to stand up to moisture and salt exposure. The 12" x 4" 8-spoke steel wheel is fully galvanized, creating a corrosion-resistant surface that holds up where painted finishes can fail. It’s a durable choice for long-term use in wet or humid environments while keeping a clean, bright look over time.
The 5.30-12 bias tire has a 4-ply rating and carries up to 840 lbs at 55 psi. Paired with a wheel rated at 1,250 lbs, it gives plenty of strength for small and midsize trailers. Each assembly meets Department of Transportation specifications, so you’re running equipment that’s built and rated for real-world hauling.
Bias construction uses thick nylon cords set at a 30°–45° angle in alternating layers. That crisscross build stiffens the sidewalls so the entire tire flexes together, helping it track straight and absorb bumps when the surface gets uneven. It’s a simple design that feels steady whether you’re moving over rough lots or gravel access roads.
This tire carries a K-rated 65 mph speed limit that matches standard highway use, giving you predictable performance on longer drives. The wheel has a 4 on 4" bolt pattern, 2.84" pilot diameter, and 0 offset for straightforward fitment with common four-lug hubs using 1/2"-20 bolts.
For extra assurance, this setup includes a 1-year worry-free guarantee—if the tire is damaged within the first twelve months, it’s replaced at no charge. That backs up a design already covered by a 5-year tire warranty and limited 2-year wheel warranty, making it an easy pick for dependable service season after season.
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"

Great product, excellent service, timely shipping. Only problem was with shipper delivering to wrong address.
the galvanizing looks very nice, they will be going on 14 foot boat trailer
Shipped Fast. Perfect fit. Exactly as described. Highly Recommended.
Purchased 2 of these to replace rusted wheels and dry rotted tires. Very happy with my purchase.
Product was great but I did have to break down the inner side wasn't beaded in the rim straight so that took some time breaking the tire down and getting it to reseal on the beas but other than that tires and wheels are nice!
Site is easy to navigate,items shipped fast and arrived a couple days earlier than expected and the tires and wheels I ordered were exactly as described. Thanks again....will definitely buy from again.
best deal i ever got will always buy these tires and wheels thank you
Needed to replace a pair of very old boat trailer tires. These fit perfectly, trailer great, look good! Would definitely buy again.
Ordering was a breeze...price was about 30% below farm store for identical tire brand and wheel.Got order confirmaton and updates re: shipping and tracking. Order arrived on date promised and it eas even better quality tha i expected. Could not be happier with purchase and will order again!
My order took longer to fill than expected but etrailer kept me informed along the way. The tires and rims look great and I plan to install them very soon.
Same goes for the wheel and tire package I purchased. The wheels are the galvanized dipped ones and they are also perfect. As far as the tires go, I don,'t even know I am pulling the boat unless I look in the mirror. I have had this boat and trailer for over 20 years and it has never looked and handles as good as it does now.
THANK YOU for it all. I will never buy anywhere else!
I actually bought these to upgrade a trailer I had for sale. It sold quickly, so I didn't get a lot of opportunity to use these tires and wheels before it left my possession. The finish and fitment of the wheels were above what I expected for the price. The tires were high quality and towed nicely. Kenda is a well established commercial tire, and they showed it in the quality of these tires. In short, I would definitely buy this set again.
Quick shipment. Will continue to order from etrailer.
Looks as if surface rust was chromes over, we are concerned how long this rim will last.
I just received my new trailer wheels and tires. They arrived at my residence quickly and in good condition. The quality of the wheels and tires seem excellent. While these are bias ply tires, not radials, I see no reason to expect anything but a good lifespan for them. I installed them on my trailer and they fit as they should.
Communication from etrailer.com was great. They informed me of the status of my order on multiple occasions, and also when it arrived, which was helpful as I was out of town the day they were delivered. Good communication is always appreciated when ordering on line. I would definitely recommend etrailer.com to anyone who needs parts for their trailer.

What I believe you are seeing is a result from dipping the rim in the galvanizing solution. This creates a rougher finish on the rim however it will help protect the rim from rust.
