I do not want to or need to start a "which tire is best" or "which tire size is best" discussion But I wonder if one of the inmates using Mefo tires would be willing to measure the rear tire width. I know that a tire sold as, for example a 130, can measure less than 130, or it can measure more. The question I am asking: is Mefo smaller or larger than the size stated on the sidewall? What is the actual size of a rear mounted Mefo? One seller of Mefo tires says the 130/80 - 18 is the same as the original rear 4.60 -18 the XR650L was sold with. The math says a 130 should measure 5.11 inches. The seller says they cannot provide the actual measurement. Is someone willing to actually measure a rear mounted Mefo to answer this question? If you do measure a tire, please tell me both the sidewall size and the actual measurement. Thanks.
