I doubt the type of tire on a 12th scale has anything to due with laying a good groove down.

More drivers, and or Sedans will bring up the grip faster.

We have the same issue at our track with new layouts, where it can be difficult to find grip for 4 mins at the beginning of the day.
By the time we get around to the first heat race it's good, and even better in the mains.

Some tracks just can't hook up natural rubber type foam tires.

This video is like a psychedelic 60's trip...lol Not that I would know

hey guys i have a random question,i was wondering how do i take apart my speed merchant 3 shock?this is my first 12th scale and have no experience with this and also how to refill it and set the rebound,thanks for any responses.

Anyone know what year or race this is?

Looks like 2004 Ifmar WC at Kissimmee Fla.

Nice battle !

Thanks for that

Pretty neat race

It's amazing when one car is faster than the other but they stay within arms reach of eachother...lol

What I really want to find is the detroit worlds when the drivers we're pulling over to watch Neisenger swoop on masami to win

I think Jelich & Hohwart of Peak Performance we're in that A main but I've never seen any of those mains or practice just heard about them...lol

I don't have any video, sorry.

But I do have a few things from that race.

Keven Jellich had his FF race body signed by the entire A-Main.
I believe this was the order they finished as well.

T.Neisinger
M. Hirosaka
M.Blackstock
D.Spashett
J. Johnson
M.Radicke
J.Rosas
C.Lett
K.Jellich
R.Hohwart

And Ernie Provetti too

The body doesn't look like it was thrown into wall...lol

Gotta love the fast fashion and I'm still not convinced it's not still a competitive body

Maybe it is perfect body for the new inline associated car?

Anyway thanks for the memories

What is the methodology on choosing the right tire diameter for the application? I understand about rollout but that can be adjusted with gearing given any tire diameter within a reasonable range.

Please explain. Does it have to do with tire flex or traction roll? Would like to understand this when trying to setup.

You sort of have it.

Lower tire profile will tend to squirm less, roll over less and chunck less. However, it will have less life.

It all depends on what level traction you have, track surface and driving ability.

I have been known to run my tires until the glue and wheel show through. One Main I noticed that my rear was sliding a bit about 3/4 into the 8 minutes, the tires were completely worn away down to the glue. Fortunately I had a good lead at the time and finished in first but it was an interesting race.

The way I view tire compound and size is a combination of forward grip, and side grip.

For instance a softer compound generally will have more grip overall, but can cause issues on a high bite surface.
By using a smaller diameter you can reduce the side grip, while retaining most of the forward grip, to a point.

For stock 17.5 blinky you can run very small dia tires, as the side grip for this class isn't as demanding as it is in mod, where corner entry speeds are much higher.

Indoor track setups will work better with smaller dia tires due to the extreme grip level.
On Outdoor tracks full size tires with a rounded edge can be optimum if you're looking for maximum grip.

is there a "minimum"recomendation for tyre sizes ?? i usually true to 42mm front 44mm rear , but i see some drivers all the way down to 39mm front 41mm rear

What do you guys know about exotic compounds

Are they mostly used outdoors

And although offset plays a factor and is different between wheel makers I wanted to know are the wheels the same diameter?

I Only run club racing and I am cheap so I like to start my tires at about 48mm (mine come at 50 and I like to get them round by my standards so it takes a little bit to get them the way I like) For the rears and the Fronts I just deglaze the surface.

Now I do get chunking and I have a lot of old tires that when I get some free time I just cut off the rims with an exacto knife and put into Zip top bags labelled with their compound.

So when it comes time to fix a tire I have lots of bits to use and contact cement them onto the tire and re-true it to a uniform size and then I do the fronts to about 2-4 mm smaller than the rears but I also chunk the fronts too so the same applies.

I have been known to test different compounds together too like pink/magenta or Yellow/black and even Magenta/black Just too see what effect mixing compounds on the outer edge (like 1cm tops) does to traction and chunking

our track changes with temperature and I like to have 2-3 different kinds of tire just incase.

in my opinion I always run bigger tires in spec classes. Gives the car a chance to roll more. Makes it easier to drive. You cant run bigger tires in mod. Mod cars do not like big tires at all.
