Gear ratio
hello, im currently using 46/17 as my gear ratio. but when i try to skid its really heavy. and im thinking of changing the ratio to 46/18 or maybe 46/20, is it a good idea? what do you think?

Skinnier tires, not new gears.
700X19 skid better but leave a smaller mark.
Brakes only if you desire greater safety.

I suspect this should have been posted in the singlespeed/fixed gear section.
One thing to be aware of is how your gearing will affect the spots on your tire where you are burning away tread during a skid. Since your crank position will always be essentially the same while skidding (right crank back and horizontal-ish, most likely), some gear combinations will result in less possible spots on the tire at that crank position. Other combinations will provide more. I don't know what the specific answers are, but this is a topic I read about a little while back regarding setup of "tracklocross" bikes. More spots is preferred to spread the accelerated wear of the tire over a greater area. It's something worth researching, IMO.

There is something remarkably Freudian with someone that is concerned with skid marks.

You should post the question in the single speed and fixed gear subforum, or the fixed gear freestyle one.
They will tell you the same thing: skidding is kind of stupid, but do whatever makes you happy.

Ironically, arguably the best gear ratio, 48-16 (the stock ratio) only has 1 skid patch.

I would suggest riding through a busy intersection, right in front of an oncoming vehicle.
I'm sure you'll leave a skid mark somewhere.
