i have a gsxr 600 and i beleive that the bike came with a 175 rear tire, i decided to go with a 190 rear tire when it was time for a new tire. a lot of people have told me that it was a mistake and that i should be careful when taking curves because the bike is not made to have such a wide tire...is that correct? can anyone tell me what concerns i should have, and should i go back to a thinner tire? im not drag racing or anything, i usually use it for in town transportation, and i dont ride it everyday. its more of a pleasure vehicle to me. its my first bike and i figured that the more tread i have on the ground the better, but some tell me otherwise. any info will be greatly appreciated.
