I'm running the MUCH smaller 37" PBR's, and apart from them not measuring out to anything even close to 37", they are hands down the best tire I've ever had. Miles ahead of the bias TSL's that they replaced. My buddy running the 42" PBR's also loves them, and he says that the larger sizes are a lot closer to being the advertised size. If I was looking to go 44's, that is probably the tire I would buy.
