Gear ratios, tyre size and skidding.
So i finally ''fixed'' my singlespeed and i was wondering about gear ratios and skidding. I've been googling violently but i figured it was best to come here and just ask instead.
Right now i'm running 38/16 With some really big tyres. I'm mostly riding a fixie for the workout so don't question that.
The roads in my town are horrible. There are potholes everywhere and to get to my destination i usually have to go ''trough'' town, Which means a million curbs. Hence the big tyres.
So I'm building up strength but i can't really see how i'm going to skid on this. I'm running 2.25 in front and 2.0/2.1 in the rear. I will buy smaller tyres soon when i get my other bike for commuting.
Also considering changing my ratios, depending on how much that will help. I ride everyday to build up strength so hopefully that will help eventually.
this is the frame i'm running btw: https://www.specialized.com/us/en/bik...rumsport#specs
everything else is customized except the crank.

That bike looks like a really fancy cruiser type, you will have a much easier time on a track or road bike frame. It is difficult to lock up the rear wheel with your weight set back. Why do you want to be skidding up your rear tire?

Well mostly for fun. And i want to learn more about gear ratios really. These kind of things fascinate me.
Edit: i don't mind stand skidding tbh. I found some vids on a good technique. I'm just stuck at gear ratios and my tyres really. I can provide pics tomorrow

38/16 should be a pretty easy ratio to skid on. but you probably won't be doing any skidding until you get some kind of foot retention.

Fatter tires tend to be more difficult because they tend to run at lower PSI's and grip the road more, but it can be done.

there's two factors which account for the degree of difficulty to initiate a skid.
-gear ratio (you're good here. normally people start out with a ratio WAY TOO BIG)
-tire grip.
plenty of factors go into determining how well your tire will grip.
easy skidding: high tire pressures (120psi+), slippery surfaces, sandy surfaces, skinny tires (700x23), light tires, downhills.
tough skidding: rough surfaces, wide tires, heavy tires, low tire pressures, poor technique, too much weight over rear tire, not committing.
the one X factor that'll get ya skidding over most anything, is consciously resisting w/ your front foot (pulling up).
