Not always. My trailer is a 50ft wedge...the 3 axles are pretty far away from the truck, and at night the tires are impossible to see when nobody is on the road behind you. Pulled over one night to get some fuel and discovered that the rear passenger side tire had blown at some point and all that was left was the rubber that could no longer touch the ground because of the limited droop. Never felt anything and couldn't see any smoke. Now I have a few running lights over the axles so I can see the smoke when a tire blows. On a 3 car trailer with 3 jeeps on it, you don't feel anything even when a tire explodes, you can only look for smoke or hope to catch a glimpse of rubber go flying, because if it's not the front axle you aren't going to see anything.
