AR-PRO (2-Pack) Universal Fit 145/70-6 ATV Inner Tubes - 450/530-6 Inner Tubes Compatible with 90cc 4-Wheeler ATV, Go-Kart, Mini Chopper, Lawn Mowers, and Hand Trucks - HEAVY DUTY Inner Tubes

I ordered these to put in my front tires of my zero turn. tires were tubeless and was losing air, no matter how hard I tried, I could not get the tires to hold air. instead of wasting money for new tires/rim I found these and decided to give them a try. they're a pain to install, use some dish soap and water to make it easier. it's raining today so I wasn't able to try them on the mower yet but so far everything looks good.

Seems to be very durable. Fit well. A little hard to install due to the small size of the tire.

Good quality replacements

I bought these because other users claimed theirs had a lock nut and the stem was metal. Mine did not. The very end of the stem had metal threads for the cap is all. A bit worried the stem will not wear well. Also, one of the 2 tubes would not fill with air. Tried to adjust the stem valve and ended up having to replace it. Also, some reviews said they received a stem valve tool. I did not. The tubes do seem to be fairly heavy duty,,,,, except for the stem.

A little tricky putting the tube in the tire, so hubby went to the neighbor and he had a smaller tool . Got it in fine then. Works great on the wheelbarrow now. Arrived quickly.
