I wanted to do that, and with a regular sized tire you'll be fine. The problem is the 37 covers the mounting holes nearest the second row seat, which is why the rear hoop extends so far beyond the vertical support. Also, I can't build over the wheel wells as my third row seats are still there. If you want to build a platform that keeps the third row seats but also can cover a 37, you need to offset the rear supports with a plate, but you'll need a spot on the floor pan to support the vertical tube where it attaches to the plate, and the floor slopes down there and there are no bolt holes, so it's just a perfect spot for stress cracking or ripping the bolt out. Trust me, I wish I could have fit it horizontally!
