從來沒有聽過mtb的輪胎有high low profile..
只有輪胎的大小，比如：26*1.5，26*1.95,29*2.1這樣等等而已。 ...
是从这边看到的， 不明白profile指的是什么？
3) Front and rear specific tyres
Many manufacturers have front and rear specific tyres, this doesn’t mean that you can’t use a “front” tyre on the rear, or visa versa, it is just the tread and design of the tyre has been optimised to provide the best performance if you use them on the intended wheel. Typically, a front tyre will have more directional knobs with lower profiles, these maximise speed and cornering traction. A front specific tyre can also be a larger profile as it typically encounters less of a problem with “digging in” and building up mud. A rear tyre by contrast tends to feature more horizontal spanning knobs that improve traction, avoiding the rear wheel from spinning in wet or muddy conditions. A rear tyre can also be narrower to improve mud clearance when the tyre begins to carry a lot of debris. What tyres should I get for my riding style?XC Disciplines – Cross country riders tend to look for fast rolling tyres, with smoother/smaller knobs and a narrower tyre width. These tyres maximise performance in conditions that are not overly demanding; i.e. normal trails and grass riding conditions. In wet conditions XC riders may look at changing their tyres to narrower profiles to increase mud clearance, as well as moving to larger profile knobs to increase traction. Trail Riding Disciplines – Trail riding requires tyres with more grip and more durability than cross country tyres. As a result they tend to use softer compounds that “stick” to rocky surfaces better, as well as wider profiles to handle more extreme cornering. conditions/more grippy tyres/softer compounds/wider tyres
