tyre size ?
« on: December 06, 2007, 05:27:38 PM »
I'm considering fitting Dunlop TT100 K81 tyres to my F1 when the rebuild is finished. Whats the best size; 4.25 x 18 rear, and 4.10 x 19 front, or should I go smaller ie; 3.60 x 19 front and 4.10 x 18 rear  ??? As the standard size is 4.00 x 18 rear, and 3.25 x 19 front, is the gearing affected, will the speedo be way out?

I have always used (boring sod) 425.18 on the back and 410.19 on the front, TT100's, shows my age a bit.

I'm with Den.

425/85 on the back (110/90 is probably the closest modern equivalent)
