You all really need address a few things....1st why fill the tires in the first place? 2nd, inquire if mechanically the machine can handle the way you are adding weight to the front end. 3rd, are there other options to add weight to solve the original problem? Really, if you have a small (but capable) machine, learn it's limitations and live with it. Or upscale. That's why they have larger models. Why all the hype on this thread if you're trying to achieve something the original equipment was not originally designed for? Yeah, I know, it's all about adaptations and project machines, but why place a subcompact on an application it was not originally intended for? all the best. bb
