2007 WR450F - Max. rear tire width? Hey guys! The standard rear tire is 110/100-18 1- Did anybody tried a larger 120/100-18? Will it fit? 2- How could I find out? Is there any charts to find the answer? 3- What is the largest tire that could fit? I used to have a 130/100-18 on my XR650R :-) That was cool. Thanks in advance.
