Looking to put Dunlop TT100's on my '73 Z1 resto. Just not sure on the correct sizes. 3.60-19 on the front, 4.10-18 on the rear or should it be the 4.25/85-18????

Hi RBY
standard tire sizes are: front 3.25 x 19 , rear: 4.00 x 18 speedindex: V
both have inner tubes and the rear wheel has two tire grippers.

Philippe, thanks for that I have the standard imperial sizes but Dunlop TT100's here in NZ only come in 3 sizes as follows;
3.60-19
4.10-19
4.10-18
4.25/85-18
so not sure which ones I should use.

The Kawasaki W800 uses TT100's as standard fitment - slightly bigger than original, but fit nice - I have a set on my A4 & recommend them

They look very "period"

Yep had them on my A$ back in early 1980's. The track true & grip well, so get my vote for the old Zeds.

There maybe other tyres that perform a bit better, but the tread patterns look too modern to my eye.

....... and Triples.

Guy's please, I don't need to be convinced about how good the TT100's look or perform, I just want some guidance on what sizes as the 'modern' sizes on Dunlop TT100's here in NZ are different to days of old and may even be different from northern hemisphere as my enquiries to Dunlop UK have just referred me back to NZ importer.
Should I use the 3.60-19 or the 4.10-19 on the front?
Should I use the 4.10-18 or the 4.25/85-18 on the rear?

I have tt's on my a1. Cant for the life of me recall the sizes after vino so i'll take a look in the morning.

Hi RBY
I would recommend the 3.60 x 19 and the 4.10 x 18 . Those get the closest to the original dimensions.
A 4.25 x 18 could be too wide and damage the inside of the chaincover.

4.10 x 19 & 4.25 x 18 on mine. Rides fine and rear fits with stock guard.
