Narrowed tires, cut and re-glued, explain the advantages....

i see in allot of the competition pics guys running narrowed tires. whats the advantage?

When you narrow the wheels and tires it brings the the treads down onto the side wall, which gives more grip on the rocks, it also makes the sidewall bigger which also gives you more grip. Hope that clears things up for you!

and more skinny the tire the tighter the spaces you can fit into

Skinnier tires have more weight/ tread contact ratio, which improves traction on a crawler. Also make them a bit easier to turn. Cutting the tread makes them softer and flexier so they grip better as well.
I used to think I was indecisive, but now I'm not so sure.

from my experiences, thats not a good thing Lowgear

Halgars right its true and they give a more realistic look too!

my new cut and shut tires. on my gecko. :) that im very happy with ...so far :wink:

Did you narrow the tire or just the rim?

both 8)

took abot one and a half inchs out of the tire and chopped the rim up to fit the tire to my liking :twisted:

Most people cut both the beads off the wheels and then just glue the tire onto that. You could norrow the tire but that's alot of work. :?

I just know from 1:1 crawlers and what r/c guys have said about the various clod tires. Wide tires are great if you are trying to float across water or snow, but when crawling, a little smaller contact pattern is better.

I also had my "smart guy" hat on when I answered that... :wink: :D :D

No one ever said that gaining the ultimate crawler will come easy :lol:

where can i get one of those hats? lol


soooo, do narrower tires realy get better traction??????
example: 10 pound truck, 2.5 pounds on each wheel if 50/50 balance
does 2.5 pounds on 1 square inch provide more traction than 2.5 pounds on 2.5 square inches? In situation 2, you only have 1lb per square inch, but times 2.5 square inches of contact. seems it would be equal?

1 lb/in^2 X 2.5in^2=2.5lbs
2.5lb/in^2 X 1in^2 =2.5lbs

maybe i need to set up an aparatus and do some scientific testing.


i can understand they turn easier because the distance from the center to the outermost traction section is a smaller distance, so less torque is needed.

kevin you are correct. i do believe there is a physical equasion for all that stuff and traction does remain equal. i know cuz i took physics... but that was like 5 years ago... :lol: so i forgot the formula. :roll:

ahhh, no need to remember formulas! the most important thing i learned was dimensional analysis.

pounds
--------------- X square inches = pounds
square inches


because the square inches cancel out. i love dimensional analysis. you don't need to remember any formulas! and let me tell ya, thats good because my memory SUCKS!!!!!!!!!!!

Kevin, the equation is:

Weight per tire divided by contact area. This gives the contact pressure.

(2.5 lbs)/(1 in^2)=2.5 lbs/in^2
(2.5 lbs)/(2.5 in^2)=1 lbs/in^2

A narrower tire has more weight per square inch of tire touching the ground. :)

You are using the weight per tire and dividing it by the contact area then multiplying by the contact area to find the weight per tire so they have to both equal 2.5 lbs cuz thats what you started out with. :D
