Built to handle serious towing, this Goodyear Endurance ST235/85R16 radial tire carries up to 3,640 lbs at 80 psi. The Load Range E, 10-ply construction adds strength without excess weight, while its N speed rating (87 mph) keeps it steady on the interstate. Reinforced sidewalls and durable tread design help it stay cool and confident mile after mile.
When heat, weight, and debris try to take their toll, this tire resists damage with double steel belts, triple polyester plies, and a nylon overlay under the tread. Goodyear’s Durawall sidewalls add another layer of toughness against punctures and scuffs, giving you the confidence to keep rolling through demanding hauls.
The 16" x 6" steel wheel comes finished in corrosion-resistant silver powder coat that stands up to road grime and moisture. It’s rated for 3,640 lbs and uses the common 8 on 6-1/2" bolt pattern with a 4.88" pilot diameter, so when you bolt it up, you know it’s a strong match built to last through seasons of use.
Skip the extra steps—this tire arrives already mounted and inflated on its steel wheel. It’s balanced from the start for smooth tracking and a stable ride at highway speeds, so you can get back on the road faster with less downtime.
Unexpected flats happen, but coverage helps keep you moving. Goodyear backs this tire with a 1-Year No Excuses Guarantee for free replacement under normal use, plus 2 years of 24/7 roadside assistance across the U.S., Canada, or Puerto Rico. You also get a 5-Year limited tire warranty and a 1-Year limited wheel warranty for added peace of mind.
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"

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at this Goodyear Endurance ST235/85R16 radial trailer tire in a low range E and it's mounted on this 16-inch silver modular steel trailer wheel with the eight on six and a half inch bolt pattern. Now, this tire wheel assembly is ideal for RVs, stock trailers, utility trailers, and even campers. The wheel itself is a steel wheel, has the modular design. When we say modular design, that's the one that has the round holes all the way around the wheel. It's very sturdy and corrosion resistant.
They do use a three-step finishing process on the wheel, which includes first phosphate zinc bath then an eco primer, and then they put a silver powder coat on the front of the wheel. A few diameter or a few dimensions on the wheel itself. Diameter of it is 16 inches, width on just the wheel is six inches wide. Now, the bolt pattern on this wheel is an eight on six and a half inch bolt pattern, and if you wanna measure that on a wheel, that's an even number of lugs. It's pretty easy because the lug holes are directly across from each other.
So all you have to do is pick one hole, let's say this one, measure from the center of this hole directly across to the center of the hole right across from it. So on this one, it'll measure six and a half inches. So that's gonna tell you it's an eight lug six and a half inch bolt pattern. Does use a wheel lug size of either a half inch by 20 or nine 16s by 18, and the weight capacity on just the wheel is 4,080 pounds. Now, if you notice, this does not include a center cap.
You do wanna center cap, we do sell those separately on our website. You do wanna make sure to get one that has the same diameter as this pilot hole 'cause when you install it, it'll go through this hole. Diameter on this pilot hole is 4.88 inches. (coughs) Now, the tire itself is a Goodyear Endurance radial tire. It's constructed with double steel belts, triple polyester cords for a nice long life, and the Goodyear trailer tire is made in the USA.
It is great for highway use. They do use a nylon tread firming belt overlay to help prevent tread separation. It is optimized tread depth and they do a decoupling groove design, which will help the tire remain cool when you're towing heavy loads. This Goodyear tire does use door wall technology, helps resist sidewall cuts and punctures, and they do even on the sidewall, have a scuff guard to help provide additional sidewall protection. Now, this is a special trailer tire design, couples the strength of a bias tire with the durability and stability of a radial tire. It is created specifically for trailers, it's not intended for use on other vehicles. And this whole tire and wheel assembly does meet the DOT specifications. Now, the tire size, (coughs) which will be stamped on the sidewall. Right here, you can see ST for Special Trailer, 235/85R16. The R means that it is a radial tire. Section width, 9.3 inches. Overall diameter from the bottom to the top when it's inflated is 31.7 inches and this tire is a load range E, which means it's a 10-ply rated tire, has a maximum load capacity of 3,640 pounds at 80 PSI. And the last thing I do wanna mention is they do a speed rating on the tire and they label it on the sidewall, but it is in a letter designation (coughs) and where you'll find that is right down here where the tire size is by the wheel. Right after it, you'll see two numbers for the load index and then the letter N. Speed rating N will mean this is an 87-mile per hour speed rate at tire. But that's gonna do it for a look at the Goodyear Endurance ST235/85R16 radial trailer tire in a load range E, mounted on this 16-inch silver modular steel trailer wheel.

All is fine. I dont use the trailer very much, but the Nitrogen fill is amazing, still holding recommended pressure. I have two Antique Car tours this season.. one is 1600 miles round trip. The other 1650 miles, round trip. I am confident of no troubles.
