Avons it is then ...
Current rear tyre;
Dunlop D402 30 17 23 DAF4 M17M MU85 B16 77H
Currenr front tyre;
Dunlop D402F MT90 B16 72H
There is just enough space to slide a finger between the rear fender and the sidewall. Although more rubber on the road appeals there does not seem to be too much space to allow for fitting a wider tyre on my stock 2005 SEEG rim.
I think that I will change them both. I don't speak "tyre-ese" so can anyone tell me what Avon Venoms to order that will go straight on without mods.
Many thanks.
Tony,
For the rear you want the 140/90 B16, which has a 77 load index like the stock Dunlop. It also is the same diameter, so your speedometer won't be affected.

Let me update that a little. Here are the sizes for the stock Dunlop as well as the 140 and 150 Avons:
D402 MU85 B16 77H
Diameter 25.71", Width 5.51"Venom 140/90 B16 77H Diameter 25.60", Width 5.60"
Venom 150/80 B16 77
H Diameter 25.20", Width 5.90"
Venom 150/80 B16 77
V Diameter 25.20", Width 6.20"
If you try the 150, go with the H speed rated tire, it is .39" wider than the Dunlop, but .3" narrower than the V speed rated tire.
