         A 130 is the same as a 5.10 give or take...
        If yer ride on lose surfaces "gravel roads" go down to
 a 120 / 4.60... a narrower tyre cuts though
 the lose top into the harder base easyer..
 A wider tyre just rolls around on the top...
 mud/sand go with the wider tyre...
 
 yer choise the tyre tread patten for what yer on
 & also how wide the tyre is...
