SwissVan Posted October 2, 2008 Share and the slippy slide at Waterworld in Benoni. Correction Johan' date=' it's called Wild Waters and its situated in Boksburg. [/quote'] and a rave held there gave us vernon koekemoer. Wild waters still going strong, does the wave pool still work?? Going back to the tyre (or is it tires) direction thread.... BEST advice is to install it as per the manufactures recomendation arrows or whatever... Remember doing a race once (Karkloof classic) and while standing on the start line pointed out to one of my subvet racing mates/competitors that his front tyre was installed the wrong way (tyre direction arrow was pointing backwards)... Needless to say he had a terrible race and complained that he felt like he was loosing the front end on corners... Never under estimate the power of the mind hehe!!!

TNT1 Posted October 2, 2008 Share Well' date=' it clearly has nothing to do with tread patterns, cause I've ridden that hill many times and the rear wheel slips, if standing OR sitting, on the road bike...[/quote'] Look TNT, you have enough experience with mature debate to know that it is easy to find extreme examples to disprove just about anything. I did say ice-rinks excluded. Why force me to exclude a bed of ball bearings, a slimy shiny wet tar road, a conveyor belt in a vaseline factory and the slippy slide at Waterworld in Benoni. There are plenty of situations where traction is extremely limited. Point remains, turning your tyre around under those (or any other) conditions will not suddenly return traction. But, conveyor belt in a vaseline factory, was classic, we wouldn't have got it otherwise Link to comment Share on other sites More sharing options...

Christie Posted October 2, 2008 Share Some excellent posts by JB and Golefty - sound technical arguments. Well done guys sounds like you know what you are talking about. Very little of substance was said to argue against their position, except that we should belive the marketing of the big tyre companies because they always tell the truth? Very poor show, just from reading this it seems like the hubbers in opposition are pretty clueless, but keeps on arguing. Link to comment Share on other sites More sharing options...
davetapson Posted January 25, 2009 Share Ok, so tell me something then - and let's exclude ramped leading edges of blocks from this discussion... For tread patterns that have some form of v shape, I always figured the v should point in the direction of force - for power (can't thing of a better description) at the rear and for braking at the front. Reason being that if you are on loose material, the tyre will slip and (hopefully) scoot the loose material away, allowing traction on harder surface below the loose stuff. The opposite would happen if they were reversed - loose stuff would get pulled under the tyre and provide poorer traction. Anyone care to tell me why I am wrong?

Johan Bornman Posted January 26, 2009 Share Now that the Hamas and Israel have calmed down, out pops Dave with this tried and proven missile. OK, I'll try though. Your question has several elements in but I'm going to deal with the one about the V-shape moving material in and out of the tyre. Most of these V-shapes in tyres are inspired not by real function but by the average tyre owner's perception of how things should work. Most of them in turn are inspired by the distinctive V-shape of a tractor's rear tyre. Their argument is that if this is good enoug for a tractor, it should be good enough for my BMW/Motorbike/Bicycle. Truth is, the V-shape works very well on a tractor and its function is purely to expel mud from the tyre and attempt to have the tyre make contact with harder substrate. On a tractor tyre it works. The tyre bed is smooth and the Vs have nice smooth shoulders where they meet the tyre. The tyre's shape is tubular. Mud is squeezed out quite nicely and it is interesting to watch those Vs at work. However, the process doesn't scale down well. On a macro scale the mud move, on a micro scale not. I consider car/4X4 and MTB tyres a micro scale. Here it doesn't work. Although a motorbike or bicycle tyre is also tubular, the crud is coarser than what those little channels can handle. As you say, you want even gravel to be maneuvred by those tyres. That doesn't happen in real life. Likelise, siping grooves in bicycle tyres don't work. On a car tyre where the surface area is large and the contact patch is square, water is moved out by grooves, but not on a bicycle tyre. Here the boat shape of the tyre does all the water evacuation.

GoLefty!! Posted January 29, 2009 Share correct, the shape of the grooves on bicycle tyres means nothing. The fancy patterns merely appeal to your subconscious. Generally on bicycle tyres,v-shapes just give the perception of more grip so you are more committed in corners, thus riding faster. You think it's the tyre but it's actually the rubber and the size of your balls. on mtb tyres the only mud clearing factors are, rubber compound, space between tread blocks and roundness of the edges between tread blocks. Edges that face each other do not clear well, edges that rest at angles to each other do.Thats why Conti Mountain King tyre works so well in all conditions. No two edges are parallel.

davetapson Posted January 29, 2009 Share Thats why Conti Mountain King tyre works so well in all conditions. No two edges are parallel. Strange you should mention that - I'm not happy with my MK's at all. Front nearly slid out from under me on one of the downhills at Barberton - in a place it really shouldn't have. Mate of mine in the UK also doesn't rate them... Also when I ride on a slope, it feels like the rear wheel is tracking downhill of the front wheel. And for anyone who's going to tell me that this is how it should be, this is more so than for any other tyre I've used. As hard as I try to like them, I'm failing miserably. Which leads one to think that maybe there is more to the shape of the grooves than is given credence. Link to comment Share on other sites More sharing options...
