You can get 15" Bundts [FUCHS] off an early 405sel , 6.9..
Otherwise , the 108/111 had them in 14", as did late 113s.
Some guys use the 107 [450sl]14", but they are 1/2 " wider.
I have the original 250L steel set so I can keep my 2 piece cap set , a 14" bunt 108 set, and the wider 107 bunt .
They are all in 14, so you can maintain the tire diam by changing the aspect ratio and still be close to orig.
Remember, the original side wall is Euro 80mm, so use this when considering your aspect ratios.....
Added note*
In US sizing , the best you can do to remain close to stock tire circumference in 14" is 195/75R/14, and if you are lucky enough to find some 15 Bunts, the ideal size will be 205/65R/15.
In the 205/14 sizes you are stuck as the 75 profile are too tall and the 70 are too short..both by about the same % amount , +/-
215/70/14 are a good circumference match, but too wide [ although, many guys use them without hitting]
Whats everyone running?
