50cc new shape on to a 200cc old shape

Does anyone know if 50cc wheel of a new shape runner would be ok on a 200cc old shape runner.. there the same size just don't know if they will be safe lol?? I like the look and due new tyres and found a new shape pair of wheels with good tyres for 35 quid cheap then one tyre lol

 

Try it?

 

Was just wondering because 50cc does what 45-50mph where 200cc does 80-85.. imangine wheel crumbling at 80 haha ouchhh

 

Oh yeah, check the tyre speed and load rating...

 

Oh so the rims should be ok just get the rigth tyres ??

 

Rim should be fine at speed, its the tyre you want to check. L rating or above should be fine, L is rated to 75mph
