What are some suggested changes or what can I expect to change when goin from a foam set up to rubber on carpet? Running an F109 with stock foams now.

Here is my rubber setup compare to the foam tire setup.

Less front camber than foam setup
Raise up front ride height 1~2mm higher than the rear, if you have a traction roll
Harder front spring, I used tamiya black spring.

Hope it helps...

Thank you

I have the tamiya front spring set, but I'm using associated pan car springs now .22s I believe these are harder than the Tamiya blacks. Good starting point. Won't get much if any practice before our first F1 race this weekend. We don't have any tues yet, but we probably will go rubber tire. So I want to go ahead and try them out right off the bat.

Default Mounting Shimitzu tires on Tamiya "Rubber" rims

As promised these are photos showing the Shimitzu F1 and F3 tires on stock Tamiya Rubber rims.
These tires can also be mounted on Tamiya foam rims too.........

I'm showing the front tires only here but the rears fit too.
You'll notice the two methods of mounting the outer tire rim.
Both work and neither seams better then the other.
I did notice though that with Shimitzu tires on these rims it does natrually through mounting give around 0.5 to 1 degree negative camber to the tire! This comes in handy for the rear of our F104's as there is no camber adjustment.
Mounting these tires on the rubber rims involves removing the outer support rim from the wheel and sand smooth before mounting the tire and glueing.
It pays to have some elastic bands handy to ensure they remain round and attached to the rim while glue dries

Any question just ask. I've mounted a few like this now. Need to try the R1 hard next. See how they fair with some hard inserts in

Conclusion
The new Pit Shimizu R1-H seemed to grip better than my used R1 (medium), but I am not sure if it's because that the my used R1 has already lost its grip. The fair comparison would be to use a new set of R1 and R1-H for the test. Note that the R1 and R1-H have thinner inserts than the R3 and R3-S. Next, I plan to test different combo out again using 3-series tires, and then finally, mix and match.
Hi There, eComet, I love how you used the graphs to represent how the tires are performing, may I ask what software to have these graphs created?

Many thanks! Cheers

Hi, I was using Microsoft Excel 2010 Radar Chart to do the graphs.

Ride Super Soft. The best i've used so far. When you compare tires, you must have in mind the setup and the motor you are using. Try running tamiya hard/soft with 8.5T motor... Ride's super soft gives you balance, great feel and stability after a couple of runs at the track. Im going to use shimizu next.

Ride Super Soft is good for colder weather because it overheats in the area where I tested the tires, in sunny California. The tires would grip well for the first 1-2 minutes and then losing grip thereafter (as noted in the Fade part).

Most racers here who ran Ride run medium front and back.

Here we ran 21.5T non-boosted motor and our tracks are not as huge and flowing as some of the Asian and European tracks (impossible to run 8.5T unless 1s Lipo), where I think Ride might be faster. For lots of turns, and acceleration, brakes, I think Shimizu might still provide more stability.

We just finished a pre-IIC carpet race at TQ RC Racing where racers who ran Ride mediums were slower than the ones running Shimizu combo. Temperature is about 70 degrees Fahrenheit.

thanks alot for the info! Im going to use a couple of shimizu tires for sure. Here @crete we have 70-75 farenheit these days and its autumn. At summer its much hotter (85-100 F). What about wet asphalt? what do you suggest?

Generally, The Shimizu F1-S and R1-H work well on all types of surface, it gives the car a very neutral balance and can last through the race time (we run 10 minutes, triple mains without any issue). They don't really overheat, but if the weather is really hot, F1-M might be better because F1-S could overheat and reduce steering.

For colder weather (less than 60 degrees Fahrenheit), F1-S and R1-S might work better.

One of the reasons the F1 R1 work well is because of the thinner insert, which provides some air gap. The F3 R3 has thicker foam insert without air-gap, like the ones come with Ride and Tamiya tires, which might make your car go faster at the expense of stability.

Most novice and sportsman racers prefer a drivable and stable F1. But for pros, they might run different setup for more steering because they are really good at throttle and steering control, and in this case, the F3 or the Ride might be a better choice (see ealier post).

In the end, you have to try them out. Just make sure before you glue the Shimizu on the Tamiya foam rims, drill at least 1 vent 3mm hole. The foam rims, unlike the rubber rims, do not have vent hole, which is required for rubber tires.
