Perfect fit, installation was a chore. A darn tire is still slow to leak though. Within a week he had lost half his air. I kind of expected the "goo" in that tube to fix it, but - inexplicably - it didn't. I've given it a few weeks and mowed to evenly distribute the 'slime', no improvement so far. Nice tube but don't expect it to fix anything but the smallest leak. The picture on the lid of the box is a joke based on my personal experience.
