speedometer off with 7 tooth?

[Scott]

In snow...lug height does not alter speedometer. Not at all.
In snow it's not really the same as having bigger tires on a truck.

Maybe on pavement it might...haven't tested that one.

Lets look at this from a different perspective. On the trail with no fold over.

7 tooth drivers with 3.0 pitch and 3" track
7x3=21
21*3.1415=6.6847 actually, 21*3.14=65.94 did you mean 22/3.14?
6.6847+6=12.6847 What does the +6 mean?

8 tooth drivers with 2.86 pitch 2.4" track
8x2.86=22.88
22.88*3.1415=7.2831 22*3.17=71.84 did you mean 22/3.14?
7.2831+4.8=12.0831 tell me about this +4.8.

Lets use a 2.5" track
7.2831+5=12.2831 And also this +5? What are those numbers representing?

Can we agree on paper the 7 tooth 3" pitch track 3" lug is geared taller?

I think I think you divided, but you showed multiply. Now I get what you were trying to say.

formula for converting the circumference to to radius

radius=circumference/pi/2

Maybe Robbie can jump in here....

No. The lug Height does not alter the speedo.. The skid is a flat surface, The belt is moving at the same rate as the tip of lug, ONLY on a round wheel does the tip run at a faster speed.

Yep, what he said.

So what you are telling me is this is not a round wheel. Where do you measure a snow tire or let's say a tractor tire? So if I run a 16" wheel with a 215 or a 265 tire the speedo will not change. I also don't get the skid in this discussion.

I'm bad. Yes it's divide. What happened to the old school symbol?

 

[Scott]

I can't find the written divide symbol on the keyboard. LOL

The computer uses the slash "/" for divide. It reads it like a fraction bar. Like 10/2 = 5.

mechanical engineer, trust me. the axle shaft will spin the same speed regardless if the track is 1/2 inch or 3 inch. The tips will excel Only while traveling in a sphere[ like around the drivers]. The skid is flat and the belting at the hyfax will travel the same speed as the tips, A wheel is not Flat like the skid.

You are correct.

Byeatts is 100% correct. This subject was beat to death a few years ago. Lol
The profile of the track gas no bearing on ratio.

No, I haven't been drinking.
When I read byeatts post, the light went on and I said I know that, so how did I get side tracked? I have no idea. Thanks byeatts.
I hope you guys will forgive me.

I'm gonna have a few after reading all this gibberish at one time.

I'm still tring to figure out how my '13 with a 3" and 7 toothers reads 42mph while my wife's '12 Assault stock reads 28mph???

THAT doesn't add up.


How is the speedo pick-up put together on these? Did something get moved or bumped or...???

Stuck in KPH?

 

[Scott]

Very possible

 

[diamonddave]

LOL.....no it's not in kph, it's in MPH.

Not sure why. Someday when I care about it, I will dig in. That is, if we ever get snow again. GEEZ.
