The only reason I gave 4 stars instead of 5 is because these irons damage my aluminum rims. However, I have yet to find a set that doesn't do damage like irons do I think. Also, the metal is cheap foreign steel, so they're a little more flexible than I'd like. 3 irons are great for a tire that isn't very stiff, but if you're changing a rear tire on a dirt bike I recommend having 2 sets, 3 irons just won't cut it.
