I used these to change tires on my 350z. The tires were staggered to 275/30R19 and 245/35R19. The short sidewall made them an absolute do-it-yourself bear (I probably just had to pay a tire shop). I used these three spoons along with a pair of Ken Tool spoons (part number 32114) that had slightly curved corners. in this. These spoons were great for lowering the bead slowly and getting a good grip on the tire sidewall. They don't have an aggressive flex, so they slip easily between the tire and rim bead. The edges were absolutely smooth, with no sharp burrs. They gave great leverage and never felt too long or too short. The grips felt good and there were no issues with shaft flex. I think they worked great and I couldn't have done the job without them. There have been a few situations where Kentools has outperformed them. Not having an aggressive curve meant you could only peek so far. The Ken tools were perfect for the initial inspection when you lift the tire off the rim to begin removal. I don't think I could do this part with just those 3 spoons. I personally recommend you to buy both sets. The extra variety was really helpful. Probably obvious, but start with the inside of the wheel (not on display). Spoons can (and will) damage the rim edge. If you only work with the inner lip then there is no visible damage. When I was done, the inside edge of my wheels was pretty chewed up, as was the bottom of the wheel.
