Liikluse suund ja rehvide kulumine

[efendi]

Tee kalle on (kui seda on) ca 2% ja see ei saa kuidagi tsiklirehvi ühelt küljelt märgatavalt rohkem kulutada. 2% meie Eesti sõiduradade puhul (2,75-3,75m) 2-4 cm kõrguse erinevust sõiduraja kohta. Minge maanteele ja loodige oma ratas ära ning vaadake kuidas rehv asfaldile toetub. Alljärgnevas lõigus on "road crown" just seesama tee kalle mida siin mitmes postituses mainitakse

OTHER THEORIES DISPROVED:
But what about road crown? Plausible and many claim it, but road crown plays no part whatsoever in left side tire wear. Though it does seem logical and also allows that in European left side driving countries, the crown is opposite which could explain right side wear there - road crown just doesn't hold up under scrutiny. The main reason the theory falls on its face - road crowns are simply not steep enough. If you examine a picture of the front tire upright, you can see that even a very steep road crown (one inch drop in one foot run) would not even contact the tire at the necessary angle to produce the evident wear. Typical road crowns are much much less (three inches drop per twelve foot run). In fact, if one examines the picture of the tire one can see that where a road crown would actually contact the tire, there is a PEAK rather than a valley (check our extreme wear pic at the top of this page http://www.rattlebars.com/tirewear/wear00.html). Plus, as described in the paragraphs above, road crown contact is mostly "rolling" contact which produces very little wear if any at all. Just so there is no misunderstanding, road crown plays no part whatsoever in left side tire wear. Road crowns, if they exist at all on a road, are completely inconsistent and vary greatly as to pitch, vary even more greatly in turns (road engineers do indeed "bank" turns), and crowns in no way contact the tire at 20° off horizontal where the wear occurs. Road crown does not cause side tire wear.
