Lets have some info based on hard facts ....... A lot has been made of 180/55 or 190/55 making the bike steer better, and a lot of nonsense has been talked about different tyres benefits, etc., and I have always maintained that the stated size is not the be-all and end-all, as different manufacturers supply tyres in sizes different to that on the side-wall ..... so lets get some hard dimensional facts ......
I have a 190/50 Diablo Corsa on at present, the overall width of the tyre across the sidewalls is 189mm and the rolling circumference (after approx. 600 miles road use) is 1980mm
So, what sizes are your tyres :O measure across the sidewalls and around the circumference in the centre of the tyre.
I am betting that not all tyres are made equal :devious
