Capt.Storm Posted September 10, 2016 Share Posted September 10, 2016 (edited) a taller tire does change the length of the tire so you would think taller lugs would also change the length/circumference of a track also.

A taller tire definitely makes a difference since it travels longer per revolution. A tracks length has the same revolution. The lug height should only come into play on hard pack or ice. In soft snow there should be no difference Quote Link to comment Share on other sites More sharing options...

Capt.Storm Posted September 10, 2016 Share Posted September 10, 2016 yeah..if the lugs are in snow the final gear ratio would be determined by the circumference of the track with out the lugs it would seem. Quote Link to comment Share on other sites More sharing options...
Capt.Storm Posted September 10, 2016 Share Posted September 10, 2016 if you took a sled and checked the speed with a 121 tack at a given rpm then put a 144 track on the same sled at the same rpm would the speed still be the same if the lug height is the same on both tracks?

Only if the track was thick enough to change the radius r then the speed at wr would be influenced by it. The speed at wR does change with the lug height but it is never in contact with the ground.

f7ben Posted September 10, 2016 Author Share Posted September 10, 2016 W is the tire cappy , the inside of the track is like the road. Nothing that is altered after W has any impact on drive ratio. Everything beyond W is a conditional variable Quote Link to comment Share on other sites More sharing options...
