The Nitrogen Advantage

Nitro Fill Logo

The NitroFill inflation process filters out oxygen to ensure that this tire-and-wheel assembly is filled with 95 to 99.9 percent pure nitrogen. Nitrogen-inflated tires maintain pressure better than tires inflated with standard air. This makes them ideal for RVs and trailers that are driven infrequently or sit in storage for long periods of time. Other benefits of consistent tire pressure are better fuel economy, improved braking and handling, decreased chance of tire failure, and longer tire life.

A tire inflated with standard air, which contains oxygen, is prone to fluctuations in pressure due to loss of air over time and ambient temperature changes. Nitrogen-inflated tires don't experience these fluctuations for a couple reasons. First, nitrogen molecules are larger than oxygen molecules, so they are less likely to permeate a rubber tire. Second, nitrogen is a dry gas, so it won't allow condensation to build inside the tire. A tire inflated with standard air may have moisture in it, which means it is more likely to be affected by ambient temperature.

In addition, the moisture that can collect in a tire inflated with standard air will contribute to corrosion of the wheel and deterioration of the rubber tire from the inside out. A nitrogen-inflated tire-and-wheel assembly is less likely to experience this type of decay. Less moisture in the tire also means reduced running temperatures.

If necessary, you can top off the tire with standard compressed air. But to maintain the benefits of nitrogen, the tire must be refilled with nitrogen.

Beveled Stud Holes

Beveled Stud Holes Front and Back

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.

Westlake Radials

This radial ply tire from Westlake is constructed with double steel belts and double polyester cords for increased durability. A protective layer of nylon is wrapped around the steel belts to help prevent tread separation.

Westlake Standard Tread Close-Up

The standard tread on this tire has solid, continuous ribs, and there are very few sipes (or thin grooves) cut into the rubber. This tire is designed for use on trailers, so it doesn't require the level of traction that would be needed on a vehicle that is braking or steering.

Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.

Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Westlake Tires and Wheels - Tire with Wheel - LHAW121 Review

Today we're to take a look at the Westlake ST205-75R15 Radial Tire in a load range D, mounted on this 15 inch silver modular trailer wheel, with a 5 on 4 and a half inch bolt pattern. Now this tire and wheel assembly is ideal for RVs, campers, and trailers. The wheel is a modular design steel wheel. When they say modular that's the one that has the round bolts all the way around the wheel. This one has a nice silvery coat finish on the front, and even on the back of the wheel. It is very sturdy and rust resistant. Now the tire that's mounted on this wheel is a Westlake Radial Tire. It's made of high-quality rubber.

It's reinforced by layers of steel and polyester belt. It's great for highway use. The tread design gives you a nice, excellent traction. They do use a nylon tread overlay to prevent tread separation. This tire even uses tread ware indicators like you'll see on your passenger car tire, and what that is you if you look at the shoulder you'll see TWI ever so often. Right wherever you see TWI that means "Tread Ware Indicator".

If you look in the tread grooves all the way across the tire there'll be a raised area, the tread indicator looks like a speed bump, its a 230 seconds tread depth. So what happens when this tire wears down, and it's a straight bar across the tire, that means your tire's officially worn out, so that tread ware indicator is telling you that. So basically as you are using this tire if you look right where it says "Tread Ware Indicator" that will give you a good visual and indication as to how much tread you have left on the tire. Now this tire and wheel assembly is inflated with nitrogen, that's why they use the green valve cap on the valve stem to let you know that. Nitrogen will maintain tire pressure for a longer periods than standard air. It also help prolong the life of the tire and even the wheel. This is a special trailer tire design, it'll couple strength of a bias tire with the durability and stability of a radial tire.

It is created specifically for trailers, it is not intended for use on any other vehicles. Also included with this tire and wheel assembly is a complementary 24-hour roadside assistance program for one year from the manufacturer. This assembly does meet the DOT, or the Department of Transportation's specifications. A few specks on this, the diameter wheel is 15 inches, and that is measured inside to inside. The width on just the wheel is 5 inches wide. Bolt pattern on this wheel is 5 on 4 and a half inches and if you want to measure bolt pattern on a wheel like this that is an odd number of lugholes, which would be five, you just pick one of the holes like this one and then you'll measure directly across to either one of these holes. When you measure you measure from the center of the starting hole to the furthest edge of the hole that you measure to.

So on this one would measure 4 and a half inches. So 5 lug, 4 and a half inch bolt pattern. This wheel does use a wheel lug size of a half inch by 20. Weight capacity on just the wheel by itself is 1,870 lbs. Pilot hole diameter, which is the large hole here in the center of the wheel that goes over the hub on your trailer, the diameter of that opening is 3.19 inches. Now the tire size, which is stamped on the side wall, ST for "Special Trailer", 205-75R15. The R designates that it is a radial design tire. Section width on this is 8 inches. Overall diameter from the bottom to the top when it's inflated is 26.1. Now this tire is a load range-D which makes means it's an 8 ply-rated tire. So maximum load capacity is 2,150 lbs at 65 PSI. And one last thing on a lot of your new trailer tires, they are coming through with a speed rating stamped on them, and the speed rating is always designated with a letter designation. Where you'll find that is right after you go to the size on the side wall, you'll see 2 numbers for the load index, and then the letter at the very end. This is speed rating L, which means 75 miles per hour. That should do it for the review on the Westlake ST205-75R15 Radial Trailer Tire in a load range-D on this 15 inch silver modular trailer wheel, with the 5 on 4 and a half inch bolt pattern.

Long wearing tuff tire. I frequently run them at max load to 45 mph off road without any issues. 669049

- LHAW121

Ordered this rim for a spare; to match what I have and the D rated Westie tire mounted; with the intention of getting 3 more of the same tire (only) in the near future. I’ve had a set of Westlakes before and trust them. Sidewall is stiffer than some and the rubber looks to be high quality. I think the brand is under-rated, in fact. I prefer etrailer for my trailer / towing needs. One concern is not getting a tire that has been in their warehouse too long. You are at their mercy as to what you get. The warranty is 2 years and that’s okay, but if I change tires every 5 years, getting one 2 years old would not be a good thing. This tire was made 5018, or the about December 7 to 15, 2018. Not too bad. Tire and rim looks perfect. 651684

- LHAW121

The tire and wheel are excellent and hold up well . I liked these four I have on the trailer so much I bought another as the spare just so I keep the same tires all the way around. They handle the loads well and they track well. Wheel looks excellent for a steel trailer wheel. 590404

- LHAW121

I needed to order a replacement tire with rim and fender for a Homesteader Enclosed trailer due to damage from a blow out on the highway. Received my order earlier than expected and the replacements worked great. You would never know the trailer had been damaged previously. 582770

Product was exactly what was shown. It matched what i have on my trailer and was what i wanted as i travel twice a year to bring my daughter to college.

Ask the Experts about this Westlake Tires and Wheels

  • Will Torsion Axle Lift Kit for Camper Allow Larger Tires
    You may be able to add larger tires if you use a lift kit, though you would also have to get different wheels for the tires to fit. In regards to clearance, with trailer tires, the general rule of thumb is you want at least 3" of clearance from the top of the tire to your fender and at least 1" of clearance between the inside of the tire and your trailer's frame rail. So with that in mind there is some information you need to know before proceeding, starting with the torsion axle you...

  • Clearance Between Tire and Frame With Timbren Axle-Less System
    As an example, tire and wheel combination # LHAW121 uses a 5" wide wheel and 205/75-15 tire, which is 8.1" wide. If the Timbren Timbren Axle-Less Trailer Suspension System # A20RS545 has 4-7/8" of space between the frame and hub face, that would leave roughly 4/5 of an inch in space between the tire and frame, so your tires would not be rubbing against the frame if that's what you were using.

  • Recommended Trailer Tire and Wheel for Tow Dolly
    The issue is that a 205/75R15 tire is designed to work on 15 inch rims and if you plan on using a 205/75/R14 tire that means you will need to stick with the 14 inch rims on your tow dolly. The best option is to continue on with a ST205/75/R14 tire but increase it to a load range D, upgrade the tire quality and ensure you keep it inflated to the proper psi. I strongly recommend the the Goodyear Endurance # 724864519, which is the best trailer tire we offer because it has automotive-grade...

  • Can Trailer With 14 Inch Wheels Upgrade to 15 Inch Wheel
    You can absolutely upgrade from a ST20575R14 tire, which fits a 14 inch wheel, to a 15 inch wheel and larger tires, so long as you have enough clearance from the top of the tire to your fender, which we recommend to be at least three inches. A ST20575R14 tire and wheel will measure 26.3" in diameter when inflated while a ST205/75R15 tire and wheel measures 27.3" in diameter.

  • Spare Wheel/Tire and Mount for a 2020 Coleman Lantern LT 274BH
    In order to choose the correct spare wheel/tire for a 2020 Coleman Lantern LT 274BH we first need to know the tire size and load range. The tire size is listed on the sidewall of the tire along with the load range which should be LRC for load range c or LRD for load range d.
