Parts of a Wheel

A wheel might look like a single object, but it is made up of several parts. To understand a wheel, you must understand the parts of a wheel. Let’s get acquainted with the most important wheel parts by starting at the center of the wheel.

The center bore is the opening that allows the wheel to fit on the axle. This is the part of the wheel that actually attaches the wheel to the vehicle and bears the weight of the vehicle. When you buy aftermarket wheels, you must ensure that the center bore is at least the size of the OEM wheel. This generally isn’t a problem as most manufacturers make wheels with a large center bore in order to fit as many vehicles as possible. When the center bore is larger, hubcentric rings are used to fill the gap. Center caps will cover the center border style.

Going out from the center bore is the center disc. This is the portion of the wheel into which the bolt holes are machined to create the bolt circle. This area is the point of contact to the axle seat, the lug bolts and the lateral surface of the rotor. Everything on the wheel connects in some manner to the disc.

The lug holes create the bolt circle with 4 or more openings. The diameter of the bolt circle is called the bolt circle diameter and abbreviated as BCD. The amount of holes and the diameter of the bolt circle is what defines the bolt pattern. Now that we’ve got the center covered, let’s move outward in our wheel anatomy.

The spokes connect the center disc to the outer ring of the wheel. The spokes give the wheel structural integrity and are one of the major elements of style in wheel design.

The outer lip is the portion of the wheel in front of the spokes. For the most part, the dish only comes into play when it is a large area. When the spokes are significantly distanced from the outer edge, the wheel is considered a deep dish wheel. This is done purely for aesthetic reasons. As the dish gets deeper, the face is more vulnerable to damage from impact.

Now, on the very outer portion of the wheel is the barrel. The barrel is what creates the structures necessary for mounting the tire. The barrel has many parts. The smallest inside diameter of the barrel is the drop center. If the drop center is close to the front face of the wheel, it is a front mount wheel. If the drop enter is close to the back face of the wheel it is a reverse mount wheel. The barrel edges are flared to create the flanges. The flanges keep the tire from slipping off. The outer facing flanges are part of the cosmetic face of the wheel.

Great Value for a Comfortable Home Office Chair
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
I’ve been using this chair for a couple of days now, and honestly, it’s been a solid upgrade from my old one. I work from home most days, so comfort matters a lot—and this chair delivers better than I expected for the price. The first thing I noticed was the lumbar support. It’s actually adjustable and makes a noticeable difference, especially if you tend to sit for long stretches. My lower back used to get sore after a few hours, but that hasn’t really been an issue since switching to this chair. The mesh back is also a nice touch—it keeps things breathable, which I didn’t think I’d care about until I had it. Assembly was pretty straightforward. Took me maybe 20–25 minutes without any frustration. Everything lined up well, and the instructions were clear enough. In terms of comfort, the seat is firm but not hard. It doesn’t feel like one of those super plush chairs, but I actually prefer that because it feels more supportive over time. The reclining feature is smooth, and I like that you can lean back a bit when you need a break. Overall, I’d say this is a great value for a home office setup. If you want something ergonomic and comfortable without spending a fortune, this chair is definitely worth considering.

Excellent Office Chair
Color: Black+white, Size: Pack of 1
I just received my TRALT Office Chair. First of all, I was impressed with the packaging of this item. When I opened the box each piece of the chair was wrapped in plastic or bubble wrap. Everything in the box arrived safely and without damage. Secondly, the instructions to assemble the chair were very each to follow. I was impressed with the Allen wrench which had a handle attached to it. This made screwing in the screws very easy. I was able to assemble the chair without any difficulty. Lastly, the look of the chair and the comfort is exceptional. I ordered the black/white chair which looks amazing. The comfort of the chair is really excellent. My back is supported by the lumbar seat and having the armrests being able to go up when not needed is wonderful. The quality of the chair is definitely worth the price.

a good choice
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
Assembled chair only to find that the lift cylinder was faulty. Would have preferred to be able to just get a replacement cylinder but calling China didn't seem like a viable option. Guessing which one & buying it online would involve paying for a good portion of what the chair cost. Customer service could only offer a replacement or refund. We're disassembling (so much fun?!) to send it back. The chair itself was very comfortable, assembled fairly easily and instructions pretty clear. Again, if we could only have asked the seller for the replacement part......**Update**...Or if the instructions that seemed so clear were clearer!, as we started to disassemble, we decided to see what would happen if the tension knob (see photo) was loosened. IT ALLOWED THE LIFT CYLINDER TO WORK. Not at all what the instructions say. At any rate, we're keeping the chair.

This chair is amazing

⭐⭐⭐⭐⭐ Absolutely love this chair! It was super easy to assemble—I had it set up in no time with clear instructions and minimal effort. The comfort level is fantastic; the seat cushion is just right and the back support makes it great for longer sitting sessions. The color is beautiful in person—clean, modern, and adds a fresh pop to the room without being overwhelming. I also really like the smooth wheels and sturdy build; it feels stable and well-made. Overall, this is a great combination of style, comfort, and value. Highly recommend!
