Tyre sizes

[garry a]

Hi I have fitted a husky 610 front end inc wheel to my 1989 100gs I'm going to put new tkc's on it rear is easy 130/80 17 but what size front should I fit a standard gs size 90/90 21 or should I go for same as fitted to the husky rim which is a 2.75 21.im thinking the 90/90 21 or is the rim to narrow and will distort the tyre profile. I haven't got standard rim to measure. Any ideas thoughts welcome

TKs are only fitted for their looks so what does it matter? they will be crap on bitumen no matter what size you use, and one you hit dirt it wont be a lot different.
