There isn't anything wrong with squatting the suspension as long as you use carabiner style hooks. Ive seen a lot of cars, sxss, and motorcycles come loose because a big bump or pothole is hit, the suspension compresses, the strap comes loose and the straps hook comes free of its D ring. I totally disagree with your assessment that the tire bonnets are "not a great way to tie down". There is a reason car transportation companies use them. Like I said in my original post, I have about 7,000 miles on my straps in all kinds of terrain. Hills, mountains, windy 2 lane, high speed interstate, high speed washboard dirt in Colorado and South Dakota, swerved to miss an accident on I80 near Chicago etc. The Talon never moved. I definitely recommend the Vulcan tire straps. The hooks are caribiner style for added safety as well.On mountain roads, driving behind people who just tie down their tires....I watch their SXS flop around on the trailer. Not a great towing setup. Just squat the suspension with the tiedowns and there is none of that!
