This is a perfectly good wheel. If it fit my chair I would give it 5 stars, but the description is misleading, thus the reduced number. I ordered three different sets of 8 inch wheels, none of which is quite right, mostly because of the website descriptions. I am a reasonably savvy shopper and quite mechanical, and an experienced do-it-yourself-er. Each time I thought, "This one is right for sure!" I have a very standard, ordinary Medline transfer wheelchair with 8 inch wheels on the rear. What could be so hard about finding the right wheel? I read reviews and all the questions on ten or more products. The descriptions and the Q and A and the reviews are all misleading. All three sets of the wheels I ordered ended up being wrong. One of the sets I can make work so I'll keep that one. Maybe this review will help you with this task which should be easy, but somehow, isn't: 1.The price point of this wheel is excellent. One can find a nearly new wheelchair on Craigslist for $75 or less, so paying upwards of $30 a wheel for four replacement wheels makes no sense. Don't hesitate to buy an open box wheel, at a slightly reduced price. I'm returning wheels that have not even touched the ground. 2. The bolt this wheel needs is 7/16. That part of the description is accurate. Don't eyeball your bolt. It matters. I did not want to dismantle the wheelchair until I had the new wheels in hand . That was a mistake. Take off your wheel, take out the bolt and be sure what you have. Take it to the hardware store and measure it on a gauge if necessary. You can buy a longer bolt if you need to, but if the frame of the wheelchair has a larger or smaller hole than 7/16 don't buy this wheel! 3. My old wheels are 8 inches, even worn down. These are called 8 inches, but they are just over 7 1/2 inches. If you can adjust your brakes to clamp down properly on this wheel, this slightly smaller wheel will be fine. But it's not 8 inches. If you can't see how to do that adjustment, don't buy this. Your brakes have to clamp down on the wheel well enough to be safe. 4. This wheel is 1 inch wide where the rubber meets the road. That's what the description says, and it's pretty standard. But it's 2 1/4 inches thick at the hub. Many of the questions about this wheel and the other wheels on Amazon ask how wide the wheel is, and I think they are all asking about the width at the hub. The answers varied so much it seems the question must have been understood. The wheel I am replacing is 1 5/8" "thick" at the hub. The length of the old bolt just fits the old wheel. So had I used this wheel, which is substantially thicker where it attaches to the chair, I would have had to shop for a new bolt, so be aware of that. (I had to shop for a new bolt anyway, because I ruined the threads banging on one of the bolts to get it out of the rusty bearing in the old wheel. And I could not find a smooth shank bolt with fine threads at the end that was the right length. So I had to switch to coarse threads, which could be your experience as well. Replacing a wheel is easy. Anyone can do it. Depending on the bolt you have, you might need two wrenches or a hex key and a wrench, but it's not hard to do. Figuring out which wheel is a match for what you have is a challenge.
