- Reviewed in Canada on May 1, 2025Verified PurchaseArrived quickly. I got tired of having to pump up flat tires on my garden trailer. The axle was 1" and these fit perfectly removed the old ones and placed these on with the two washers and codder pins from the old wheels. These had bearings the old ones didn't. They also came with bushings to fit a 5/8" axle. They can carry any load I put in the cart. If your tired of looking for a pump to get the job done these are perfect.
- Reviewed in Canada on August 22, 2024Verified PurchaseSo far so good, we use the trolley daily and it is holding up for the month use.
- Reviewed in Canada on September 21, 2024Verified PurchaseI JUST UPPED MY RATING BECAUSE I HAVE BEEN LOADING THE TRAILER WITH LOTS OF ICE STORM, HEAVY WOOD. [OLD] ADDED TO GARDEN TRAILER. SO FAR GOOD.
- Reviewed in Canada on July 16, 2022Verified PurchaseIt was hard to find a tire and a rim that would fit onto a one inch axle for my little trolley. The trolley is handy to pull the boat out of the backyard. I am glad that you never have to deal with flat tires with these polyurethane tires. Easy to install and more sturdy than a regular tire.
- Reviewed in Canada on March 27, 2022Verified PurchaseI got 2 of these and just before mounting them I checked the bearings to see how smooth they were and was surprised at how bad they were. Of the 4 bearings only 2 were barely OK, the third one felt like it had gravel in it and the fourth was so bad I could barely turn the inside race by hand. Then there is the issue of the load capacity. The picture states it is 110 lbs and the write up states it is 330 lbs. So what is it. I will likely return these. If the bearings were OK I would keep them.
I stupidly decided to keep them and now find out they are NOT flat free. I used them on my log splitter and after sitting for a few hours they go flat on the bottom and are hard to roll. if they are rolled so that the flat is on top, they will eventually return to round (on top). So they are certainly not flat free and certainly not capable of handling 330 lbs, as stated in the description. Waste of money and now I am too late to return these.
- Reviewed in Canada on September 16, 2022Verified PurchaseI bought this 'wheelbarrow' tire and promptly returned it as it is not suitable for heavy loads AT ALL. Double check the specs, I believe it was 150lbs max. If you are putting anything heavy like stones/dirt/cement into your wheelbarrow (what else is it for????) then do yourself a favor and get proper pneumatic tires from Home Depot or your local hardware store.
- Reviewed in Canada on September 2, 2024Verified PurchaseVery sturdy, perfect
- Reviewed in Canada on August 3, 2024Verified PurchasePerfect replacement for pneumatic trailer dolly wheels. Hard to find elsewhere with a 1” axle.

5.0 out of 5 stars Careful of hub width
Verified PurchaseI got in a hurry and didn't pay attention to the hub width I needed. As a result, the hub is wider on the new tires and barely rides on my axle. I made it work kinda, sorta, but not ideal. I still gave them five stars bc they are what they say and decent quality compared to others I have bought. If you need to find out your existing width, run a wire or stick through and mark at your bearings, then measure. Hope this helps!

4.0 out of 5 stars Ideal pneumatic tire/wheel replacement, But specified axel fitting measurements wrong!!
Verified PurchaseBeing a solid rubber tire, you don't have to worry flat tires!!
The axel measurements indicate 25 mm diameter! WRONG!! Actually, it is 1 inch!! (25.4 mm.)
Through the hub distance is also more than 3.3/4 inch, more like 96 mm!!

5.0 out of 5 stars Replacement tire for wheelbarrow - good quality, fair price, and perfect fit!
Verified PurchaseI used this tire on a wheelbarrow that had a tire that consistently went flat. The diameter of the wheel and bore were just as specified and was a perfect replacement. This unit is well made and I appreciate that I won't need to worry about the tire going flat. Great value for the price!

5.0 out of 5 stars Worked perfectly
Verified PurchaseI had a small utility trailer that had larger tires and I could not and did not want to put a lot of money into replacing the tires. I decided upon these and they are smaller however they were perfectly. Couldn’t be happier
- David in AlbuquerqueReviewed in the United States on May 20, 2025
4.0 out of 5 stars Fit Nax Haul Dolly without problems.
Verified PurchaseFits a Max Haul trailer dolly like the original hub and wheel. I was skeptical about the fit but it works on a 25MM shaft. Not sure how it will hold up and the hub seems light weight. I plan on keeping it inside rather than out in the sun which will probably deteriorate the tire portion much quicker. Very reasonably priced,
