Tyre Sizes!!!

[Toolboy]

Gday all,

I am looking at replacing both front and rear tyres on my TM400 (3.0 x 21, 4.0 x 18 std) and RM370 (3.0 x 21, 4.60 x 18 std).

So my question is "What tyres sizes does this convert to 120/100/18"??

and for owners of the following bikes "what size tyres/compound do you use on your suzuki's"

Thanks

Tim

80/ 21 for front, 110/100-18 rear for both bikes

As per Robins post      front   80/ 100 X 21       Rear   100 /110 x 18

On my 4  bangers  MC 5 front & rear   = Tend to last longer 
          2  smokers  Deli Tyres / Terra cross    =    value for $$

100/100 = 4.0
110/100 = 4.5
120/100 = 5.0

100/90 = 4.10
110/90 = 4.60
120/90 = 5.10

Michelins use their own sizes that relate to tread rather than carcass - basically, they're a size smaller than the numbers suggest.
