Got a 45 front and 40 rear. Front is fine but rear wore down faster than any tire I've ever owned. Got little cuts/tares after only a month or so of riding. And then started getting flats on the road after like 4-5 months of riding.
Love the feel and proformance absolutely excellent tire for feel and has just enough grip for gravel and a little mud, super smooth on the road. Can't afford to go through tires that fast so will have to think hard before getting another rear.
