17" on standard sudan

[itHaKa]

for 17 inches i recommend no more than 7 inches if you have stock guards , because the front wheels needs to turn ...

for offsets, the higher the number, the better, since you can always put spacers to get the rim to the outer side
offsets et 52 - et 55 are key

not sure if you have short swing axles, for short swing axles you will need spacers on the back
i am running cup 3 twist replicas with 17 X 7.5 et 52 all around , long swing axles and no spacers requiered for the rear, for front i have a 2 inch narrowed beam which helps but a 7 inch rim would have fitted better

sorry about my english
just my two pesos ,i am Argentinian
