Default Foam Sedan tires. Front type & Rear type. What's that about?

I have started noticing lately that most foam tires manufacturers are now making different front and rear foam tires.

Some that I have seen:
- Treadz
- Yokomo
- Suger G
- Even pro-line

What's the difference between them. Maybe size? anything else?

thanks.

Different manufacturers make their own branded tyres, some make them especially while others source from one location.

foams are pretty similar accross brands, find whatever is available locally and play with different shore, ie hardness, start with 35 rear and 40 front and work from there. The lower the number the softer the tire, and the more grip it will generate, but will also wear quicker.

A brand that is popular over here is Ufra, they are mounted cheap and long lasting and give heaps of grip.

i think what rodneybarrett ment was why are there different kinds of front and rear foam tires...

like, a 35 foam tire, theres one from the front and one for the rear, whats the difference between the 2?

If I'm not mistaken companies do this because in general racers match up tires like double purples front/ purples rear, so to make choosing tires easier we call double purples xtra hard fronts, and purples xtra hard rears.... doing this someone who doesn't really understand the whole foam concept can choose a matched set quite easily. However hard fronts may also be purples with hard rears being pinks.... these are all just compounds listed out of my head and probably don't equate to what you may be buying, just an example......

However.... CRC Xtra hard dual compound fronts are the same as Jaco plaids, and CRC Xtra hard fronts are Jaco purples, but they seam to wear alot longer than Jaco's and are mounted on 2.0 inch (inch-up) wheels.


BTW: I only use CRC foams, bringing the track magnets to touring cars is the single best thing that ever happened to racing and me!!!!

IMPACTPLAYR and Disaster999:

You guys understood my question exactly. Thanks for the responses.

Now what if you see something that says purple front and purple rear. It that really the same tire and compound or is there some other difference that I am missing?


I am trying to find some good combinations to work with.

I have used TRC purples and pinks. They handle great but the pinks wear out too fast. I have also used the suger G's in 45 and 40 compound but I am getting a slight push and wanted to lower the front compound some (the reason for looking at other tires and noticing this front and rear thing) to see what happens.

Try the CRC foams I use or Jaco plaids and purples. Plaids are basically purples with an orange ring around the outside. This gives you a slightly firmer front, but not quite a 5 shore difference. The purple/plaid combo seems to work quite well in a wide range of conditions such as carpet and indoor/outdoor asphalt between 50-125 deg.!!!!! EVEN WITHOUT TRACTION COMPOUND!!!!

I can't say this is true for all the brands, but I've been told this about Ellegis and Treadz (which are made by Ellegi)...

The front and rear compounds are slightly different hardnesses so that the wear will tend to be equal front and rear. During a long nitro main uneven tire wear front to rear will cause the car's handling to change. So when you see a pair of Ellegi 40 fronts they're not the same as Ellegi 40 rears, but they should wear at the same rate on the car.

I got this info from a Treadz dealer a few months ago at a race in Maryland, I was asking pretty much the same question then.

I was told simular information. They Treadz told us they were a different denisity foam front and rear. With you mentioning the wear factor this makes more sence. TC are not like my vector with a front 1 way and a straight axle odr of .98
