I just installed E track in my enclosed bike trailer. I would not use screws. I used 1/4 in bolts with flat and lock washers. May be overkill but i dont want to open the trailer to a pile of bikes. I put a bolt every 4th hole so i skipped two unless it hit on a crossrail then i put one in it too. I layed it out drilled the holes and got a buddy to hole the bolts while i installed the washers and nuts and tightened them up. The bikes weigh 500-800lbs and i compress the suspension when towing and try to use a spot where it has a bolt.

I have it in my enclosed and i haul atv's and bikes and have never even seen them give at all and mine are screwed into the floor, although i did use every hole! We use them at work to tie down everything we haul and i work for a trucking company, and we tie down things that weigh as much as a car easy. As far as your over the tires deal, i would also tie it around the axles through the d-rings and it isnt going anywhere!

Here is the ticket on this!!! You can use wood screws on most holes and then get a self tapping metal to wood screw and put them at each frame crossing! I have this in my 48 foot 2 car enclosed trailer and it holds the cars fine... Just make sure to use self tapping on the frame crossing!

If you cant see the frame joints then I would do the bolt with washer and nut!
