3.50 x 19 ribbed front
Unfortunately down here it have to be a V rated tyre, a little quicker than the M20 will go
And a K 81 on the rear
I like the handeling better with the rib on the front and have found in general girders seem to handle better with a ribbed front.
Thank you all for that great input! I think that you have helped me make up my mind. Since I'm going to put the front mudguard on the back (none on the front) I'll make it fit with the big tyre. I currently run a BMW R80 chopper on knobblies so I hope I'll cope with the reduced handling capabilities. Thanks again one and all.
