[barncobob at aol.com]

i have a stock 65 tiger with 13" minilites and 205/60/13 tires.
i want to upgrade to 15" something(panasports or look alikes)
i do not want to do any body modifiations.
is there a wheel of this type in 15" and tire size etc. that will work.
i would really like to hear from someone who is currently running this combo'
do u need 6" on front and 7" on rears?
