I love my Yakima hitch rack. But I did need a hitch extension.
All we needed was a couple inches extra and a smaller insert since we didn't have a hitch small enough to fit the rack.
I have 31s but as you can see there is plenty of room for a 12" wide tire.
Fits one road bike..
Or a mountain bike and a road bike.
There's space for four bikes but I wouldn't put more than three on it. That's just me acting like a scared parent but my uncle has had a brand new road bike fall off and crumble against the road(not with this rack). Like my jeep, my bikes are my babies.
