They do smell initially, yes. My understanding is that this is just a bit of outgassing from the manufacturing process. While the odor was quite strong when I opened the boxes, it wore off after about a week or so. Though I never had the need to do this, some have said leaving them outside for a few days in the sun and rain will help speed things along. I'm not sure how my ramps differ from yours Dan, but the smell on mine wore off much faster to the point that after about 2 weeks it was completely gone. You could ride in a hot car/van with them and never know!
