D30 15 - 35゜C
D35 25 - 45゜C
D40 40゜C -
The above is for standard chart for selecting tires. Depending on surface
condition ; dusty surface and by use of grip agent etc., choice of tires by
compound will change

NOTE 2
On operation, 　temperature of tire will fluctuate. As the result, the the
characteristic of the tire changes

1. Change to soft inner
2. It makes bigger hole on the wheel or make another hole.
3. Change soft wheel
4. Change hard tire

HOW TO CHOOSE TIRES FOR M CHASSIES

Difference of characteristic  RADIAL AND SLICK TIRE

RADIAL TIRE

D98J RACING RADIAL TIRE
 
SOFT/MEDIUM/HARD/EX HARD

Get high performance at various surfaces like

is smaller.  As the result, it is not easy to
overturn

SLICK TIRE

RACING SLICK TIRE FOR M CHASSIS

HOW TO SELECT OF DARDNESS OF TIRE
 
DEPENDING ON DRIVE TYPE, THE SELECTION OF HARDNESS IS DIFFERENCE.

FF DRIVE : 4WD

4 WHEELS CHASSY

Basically, hardness of both rear and front
tires are the same.
Depending on the characteristics of chassis and/or body, it  is possible to  get better result by putting different hardness to
front and rear。

ＲＷＤ　REAR DRIVE CHASSY

F1-S (FRONT SOFT)

COMPOUND
F1-M (FRONT MEDIUM）

COMPOUND

R2 (REAR) COMPOUND

special pavement road. Especially, high grip
power gets on the road where the use of the
traction

R2 (REAR) COMPOUND

For carpet and oil surface.

F3 (FRONT) COMPOUND

The above two type tires are easy to pick up
dust and rubber dust of tires, and, it does
not get good grip power.  For those track, this tire can get hight grip power without traction.
