3rd rear tire??

[Atv999]

Has anyone on here heard of or have tried running a 3rd rear tire in the center of the axle? If so, are there any recommendations on tire size, rim width, etc..?

Mike Clements did it. I dont remember if it didnt work or if it was banned.

What would be the point of a 3rd rear tire? That sounds like it would be a pain to get off and on.

Mark Bergfelt ran two RR's for awhile.
Don't know if he left for the Nationals yet but you ought to talk to him about it.

Unless the center tire was bigger I think it would be a pain in the butt.
And if it's bigger how would you ever have any stagger.
You'd have to setup to either run middle right or middle left switching between the two.

If it's smaller the what good will it do unless yer a big old super sumo racer?

I've heard of it. I've also heard it doesn't work because you push like crazy and it's allot of useless rotating mass.

Correction you would have stagger when the weight is on the LR and the RR is being slipped.
Heck might be ok thinking about it now.
And if your rolling the corner you could roll it on the center and RR.
... so ... heck maybe ... try it

I had a fella mention it to me at our track yesterday. He said he has seen guys running 450 karts running them. He thought maybe it would help us out on our small tracks with higher hp engines.

I believe the tire on Mike Clements was mid chassis on the right side .
May have been banned or just to far out of the box .

This was different than Mikes mid chassis mounted kart. Probably the first out of the box setup I remember seeing on Bob's and I'm sure it was before the big site crash.

Would love to see a picture of that.

Would love to see a picture of that.

mikes tire was mid mount on the right side

Seem like it was in the wka magazine around 05 but i can not find any pictures of it or the twin engine mount he had .
I believe it was adjustable 2 ways toe and surface pressure ..

 

["J'-remy]

old beast class (4 cylinder sport bike engines) ran a long axle and two right rears

 

[CarlsonMotorsports]

Mike's (Clements) was ran between the frame rails of his chassis (Cheyenne?)
Mark's (Bergfelt) is a "dually" hub that you put on the right rear.

Mike Clements chassis had a 5th wheel in the middle right side (3 wheels front, middle, and rear right side) of the chassis. He said that it did work and was banned at some venue's. I talked with him about this chassis after he sent it to me in a email. I don't have that email anymore otherwise I'd show picture of it.

 

[sundog]

I wonder what grounds they banned him on, just because we didn't think of it?
