I recently offered to help a person change a tyre following puncture. They had a long type nut wrench which made it very easy to compared with the wheel brace which i was accustomed to. Decided to buy of these wrenches but found it would not fit on to the nuts of my car (almeira 2006). the "thing" to fit onto the nuts had two markings 17 and 19mm. will i have to try and find the relative size of the nuts and proceed likewise with the wrench. sorry for being long winded but i am not "into" cars.
