Hi all.

Would like to replace my ageing Pirelli City demons with some BT45s and and would like your views on the most appropriate sizes to fit,Have found that one makers 3.50 H 18 and 90/90 H 18 will physically be of a different size to anothers! so what should they be

Thanks,Dave.

You really can't go wrong with 90/90 front and 110/90 rear.
