Are you gluing a bead or just spaced dots? Inside,outside or middle?
I have a box of rock hard vintage Tamiya front tires (diplo ect) that I have been thinking about sacrificing.lol
How about chucking them in a lathe and cutting grooves in them to fill with glue?

Btw.. I have been getting some BIG time help from a former tcs f1 champ (and Cali driver).
I feel that the older number HBR Mediums have less steering than the newer number HBR Mediums.

What's up robk? Been good?
I glued up the sidewalls too.

When I did the glued slits, I made 8 slits around the outside edge thinking it would also help keep the wear down on that edge since that is what gets the most wear.
It worked well but was not perfect so I also did the inside edge and it was very dialed.

I made the slits with a pair of small wire cutters/dikes.
I opened them up a tiny bit then pushed the tips into the tire about 1/8 of an inch deep then pinched a tiny slit that looks like a mini smile.
I pulled the slit open and put a drop of glue in each one.
Done deal.

You can try just puttin several drops on a set of tires without cuttin slits and see if you like it cuz it'll wear out quickly and be back to normal if it doesn't work for you.

I assume that you are running the front black springs? I run front black springs with a 1.5mm spacer. Stiffens up the front end a bit. You might try useing the Tamiya mediums and the spacer in the front springs.
Also you can use Zac projetc tires as they go all the way up to 45 shore for fronts.

FN,thanks for the pic.

I took a set of med. fronts yesterday and cut two bands in them on the lathe.
Looks like I could try fitting a o-ring in the grooves (not sure if that will work or not). Or I could sling some med ca in there. Either way it's got to help.
What are you guys running for rear tire diameter? My soft rears are getting pretty low on the rim (50mm).

j.d. what are you running front tires at (mm) ? If your rears are at 50 Iam thinking the front are close to that, how are you getting your front ride height to a useable setting? I have been using the shaved steering hub method but can only pick up 1.5 mm. Thanks in advance.

Default Random tire thought

I notice that the F104 runs better with smaller front tires. I'm wondering if gyroscopic balance between the front and rear makes a difference in these light cars. A heavier tire with a larger diameter would create more gyro effect.

When you change the force on a gyro (a steering input, for example) another force known as "precession" occurs. Simplified, when you turn a rotating wheel to the right, precession wants to make it lean to the left. The slightest movement will cause precession and the reaction is instantaneous.

When the wheel is heavy enough, there might be enough precession to make the car want to turn more, which you'd correct by steering it to the left, which would start the process all over again. You end up with a car that wants to twitch left and right with no rhyme or reason.

This, of course, is only a theory.

Stabilizing it by adding weight to the rear rims?

Doing the same. I can pick up about 2mm.

Thanks bakadude,

Yep, that is one of the tricks I tried along with many others from the F1 gurus that are out there.

I always run Tamiya HBR Mediums up front, preferably the older # as I feel they have less steering than the newer ones.

I don't sauce the fronts at all, ever, on asphalt. Carpet, sauce varies.
Just use the sauce of choice for that track, match what is being laid down by the other cars.

I also always run the black front springs but don't like the spacer, gets unpredictable and doesn't seem to make it push any more than without the spacer, just seems to skip around a bit more.

The harder compound tires seem to take away all of the steering and not just some of it.

Still think there is a magic durometer/shore rating that I haven't found that will get it just right when the mediums bite too much.
Til then, the superglue has me pretty happy.

The premounts are about as close to perfect as you can get for touchy asphalt.
