I have the newer Thule Sidearms on my roof. Been deflating my fat bike tire to cram into the front over the last 2 years without issue. HOWEVER, 3 weeks ago on a 4 hour drive the front tire continued to deflate on me to the point where the hook had nothing to grab on to. Bike came off the roof rack at 120km/h. Luckily nobody ran it over nor did it go through anybody's grill. Tough bike though, all it needed was new bars, stem and grips.
I now add a toe strap to the front wheel as well as deflating the rear tire to the point where the stock strap works instead of relying on a toe strap.
That's what I get for using the wrong tool for the job.
I also gave up on continually removing the roof rails/towers from the car. I'll take the 0.5L/100km hit on the wallet vs. scratching up the door frames/roof.
I don't notice the fuel issue when there are no bikes on the roof. When the bikes are on the roof it's like driving with a parachute off the back of the car. Driving back from Marin County a while back I did the I5 Sacremento to Eugene stretch into a headwind. Got slaughtered in fuel consumption, was so brutal . The rear racks are much so better IMO, although it feels like a big hit in the wallet for the hitch and rack cost. Way cheaper in the long run for sure
