Review: Arrived quickly and as expected. No concerns with the product. - The product arrived quickly and as expected. Overall quality seem good. The valve stem is offset from the center, as in the picture I appreciate that! I did struggle quite a bit replacing this tube. I do not feel it was any issue with this product, moreover, an issue with the quality of the rim. I overloaded my original tire and had to draw horizontally and it poped this also caused significant damage to the rim. I repaired the rim and when this tube arrived I struggled installing it. The valve stem pulled in when seating tire bead, againwhen filling. I ended up using a flat washer and a wire tie to keep it in place. ( I would highly recommend this). This was no fault of the tube or the product more an issue with my rim. I have replaced many tires, tubes and all sorts of vehicles, cars, trailers, atvs, BMX. I struggle with this replacement due to the rim and tire. I did make this repair and able to use the dump cart, but also ordered, a no flat wheel assembly, to install later. Overall this product performaned as it should, and would recommend, but only if you have a quality rim!
