hey maybe its different on dif year maxi's, you might be ok. I was trying on a 78 mkII sport.
I have a couple sets of those old skinny wheels that the early maxis have i know they need the 2.25's and i can bet they will be a nightmare to put on there, so skinny!
Honesely though i just got 4 sets of the 2.5's and 6 of the 2.25's so if it doesnt work id gladly swap a 2.25 then i can mix up a set front and rear.
God if this works out and they deliver all these damn tires for free shipping im gonna be stoked , ive paid almost the same amount for 2 sets before, and i got tubes coming for all these too, and they are gazellles ( crossing fingers! )
