Really good tubes

  • Quality tubes
The tubes worked perfectly on my golf cart.

  • Good price
Got 2 for not much more than the price of 1. I installed it on my golf cart that had a leak around the bead. Arrived in one day. Only reason I didn’t rate it 5 was because It has only been on for a couple days so if it lasts, the 2 pack should be rated 5 stars.

  • Made mowing the yard fun again.
Great for keeping the rear tires up for an entire day and not carrying around a plug kit and air compressor. (Spent more time repairing tires them mowing) . Going to add four more to the next order for my grandkids trail carts and mini bikes. now I can get the lawn done in 3/4th the time it used to take. Holds air well , and after a total of 15 hours it still holds air, my lawn is 10 acres and there are cactus all over it. So far nothing punctured them. ( I also filled them with Slime for tubes when installed as a precaution) . Next set I get will be for the bigger Husky . ... show more
