I have a 1982 Honda CR480.The rear wheel is a 18x1.85 which needed replacing.The bike wreckers tell me it should be a 18x 2.15.Can anyone clarify this.Not even the genuine workshop manual gives specifications for the wheels.Thanks

18x2.15 ist the right size.
18x1.85 ist for the CR125. if your hub is also of the CR125 82 you will have a problem with the chain line. it is 5mm towards the rim in relation to the 250/480.
