There are not too many manufacturers for the Bullet-specific tyres anymore. On the other hand it´s easily possible to order from all around the world with low price differences.
I´d like to summarise all the experience with well and less well known tyre brands, as by now these are spread ll over the forum. If possible, post e-mail-addresses or phone numbers for availibility, aswell as prices.

List will be completed bit by bit. I focused on the odd 19´ as the EFI-18` are easier to get. Input is welcome, I´ll update the list accordingly.
What I didn´t get is this 3.60/4.10-thing. Are these usuable without disadvantages? What is the difference between 3.25 and 3.60 respectivly 4.10 and 3.50?
