Coned wheels effecting downhill?

For all you experienced downhill bombers out there I have a question. If your wheels are coned or developing a small flat spot on even one wheel, will that effect the boards performance for downhill use? I understand it will feel more uncomfortable and develop vibration, but could it say impact on stability ? If "yes", is there a speed range where issues like this come into play and are more noticeable?

more coning = less grip? probs wait on faster riders to say something

Wtf?

love the italics in use.

coning your wheels, is basically losing grip, so going downhill and hitting a corner you may come unstuck.

flatspots in wheels, reduces your speed because there is constant rotation, but its like rolling over a speed bump (or crack in the pavement) over and over is gonna reduces your speed.

i wouldnt suggest hitting over 50km/h before you either get vibrated off or you just wanna crack into a nice slide.
but i'll comfortably say "the day you catch me bombing on coned wheels is the day i live in a trolley"

coned wheels are rad for sliding but they are slow in a straight line. i have heard that they have more grip because of the more surface area but there are no good things that come from flatspots.

nah mate, because of the cone shape on the wheel there is actually less pressure on the inside of the wheel when your going into a turn and on the straight the inside of the wheel in bad cases wont even touch the ground --> which is why k-rimes and james kelly give away there set at the end of each race.


Richard if you think of a flat spot well try to imagine a square with curved edges rolling... although our wheels don't get that bad. it will effect your speed and grip when turning as you can bounce out of the corner.

coned wheels bad for downhill flatspots even worse. Run fresh wheels.

Thanks for the replies so far. By the way, the reason I am asking is that I have one board for my freeriding/sliding and downhill.  My street is good for at least 80kmh. Being new to downhill, I currently ride in the 60 and under bracket practicing short bombs and lots of sliding and stopping practice. I am just wondering what to expect especially in regard to stability and control, now my wheels are coning as I try to increase my speed.

Last run at around 40- 50 my board felt totally different in a bad way. I don't have the luxury at the moment of a fresh set of wheels or dedicated downhill board.

You'll work it out as you go Richard, most of this stuff is just commonsense. Like asking if you can drive a car in the rain with bald tires... Can if you want just be ready for it.

my freerides, which are pretty much to the core are not round, and anything above 40km/h will just throw you off...
