I can't find a tube for this tire size. These tires are on my lazer hp and a nearly brand new. Picked up a nail near the side wall and it won't hold a plug and the slime helps but still requires air every week. This is now my personal mower so I rather spend 20$ on a tube than 80$ a new tire. I usually get my stuff on j-thomas. Anyone have any other suggestion to where I can buy this size tube or if I can get away with a slightly different size tube.
