Sir you are 100% right. Though the width is the same, surely the size of the tyres will/ may create problems. In fact i had the plans to make a custom built/ self designed trolley from the rear tube of a suzuki but found this one ready made. The only advantage of this one is of the extra ordinary light weight, it being made by aluminium (around 35 to 40 Kg's). I have tested it on road, not yet checked off road. Will surely share my experience once move it offroad. Lets hope for the best.
