Just finished fitting new MITAS E08 tyres FROM TRELLBORG
http://www.trelleborgtyres.co.uk/category_Trail_1.htm . To all those that ask will a 140 fit the rear wheel the answer is yes. If you look closely at the last photo you will notice that the bike is resting on the rear swinging arm after I used the side stand to break the bead on the rear tyre and the main stand slowly came off. If you think that getting the bike onto the main stand is hard then you want to try it with out the back wheel, that is VERY HARD.
