6" tires, both axles?

[Sir Steven]

Hello,

I have maybe a stupid question.

If you run 6 inch tires on a 2.2 must you on both axles 6 inch tires?
or is it possible with just the front of rear axle 6 inch and at the other axle a normal tire?

Thanks,
Steven

I think some words are missing lol but I think I understood it, you could use a bigger tire on either side and then use a smaller tire opposite of that, it would create a over and under drive because the smaller tire is going to spin faster

 

[Sir Steven]

ok, thanks for the answer!

Smaller tire will spin slower at a given speed. The greater circumference of larger tire is the reason.

So to over drive fronts, 6" tires on front, smaller on rear. Unless rears are quite a bit smaller, not sure how much difference there will be though. You would be better off doing this with axle gears if thats what your after.

?????? if two wheels are spinning at the same speed but one is larger than the other, the smaller should be the one spinning faster ish because it doesnt take as long to do a full rotation like the bigger wheel.......... so it should be the smaller wheel in front not the bigger?!?!

its the same principle as a screw driver handle, the handle is bigger so that the force and distance is more than the actual phillip head

If the axles are geared the same, then the tires will make a complete revolution at the same speed. The circumference of the tire is the distance it travels in that revolution. The larger tire will travel further in the revolution.

In one revolution a 6" tire will travel a little over 1.5" further than a 5.5" tire.

Put the larger tires in the front for an overdrive effect.

 

[Erin]

Yep. Put a point on each tire, the larger tire has to travel further at the same axle speed, so its covering a greater distance. All things being equal, it must move faste to keep up w point on smaller tire.

Or imagine two circles, one inside the other if that helps. This confuses alot of people.

"thumbsup" Wheelspeed is identical, traveled distance is not.

 

[C*H*U*D]

if two wheels are spinning at the same speed ...the smaller should be the one spinning faster

I think I see where your confused :mrgreen:

[EeePee]

Wow.

Did it on my Losi truck with the stock Rock Claws on the back and the bigger Comp Claw on the front. It helped a little bit. I even made a video of it.

maybe a visual for demonstation

We have Nascar style races sometimes in our club....so I put the larger tires on the passenger side of the truck and the smaller tires on the driver side....that way I can drive using only the throttle and not the steering!

+1. (I agree with others as well......)
Axle/wheel speed is the same (provided ESC's are the same, motor winds are the same, gear mesh is the same, etc.......) but CIRCUMFERENCE is different, thus distance traveled is different for a given wheel/axle speed."thumbsup""thumbsup"

How does that handle on the straights?:mrgreen:

Think of a record player (for those who remember wtf they even are) spinning a record. If you were to measure speed near the spindle and again at the outer edge of the record, you would have two different speeds even though the rpms are constant.

The same goes for tires. Though the rpms are constant, a smaller tire will spin more slowly along its outer edge (the tread) than a taller tire will.

That was what I was trying to explain when I said about one going faster, but it looks like I confused the speed, really thought the smaller would spin faster,

If you wanted to cover the same amount of distance in the same amount of time as the tall tire will, then yes, the smaller tire will have to spin faster.

But still, while the rpm of each tire may remain constant, the speed at which the outer edge travels will vary depending on how far away from the center it is.

RPM = measurment of speed, you are incorrect sir. If the inside of the record were spinning at a faster speed it would horribly warp the record :ror:

Think of muscle cars that we see all the time, very large tires in back and tiny up front.... all wheels travels at same speed.... so changing the gears is the way to go.
