Yes indeed! There are plenty of fake Yokos being smuggled from neighbouring counries that enter via under invoicing.
If you want Dunlops go to Spinzer, I have given the number
If you want genuine Yokos, go to Sheikh Brothers behind Hotel Faran on Shahra-e-Faisal. Their rates are 500-800 more than more (for each tyre) but genunity is guaranteed because they are official importers of Yoko.
Fake tyres won't have rubber spikes and coloured strips. Originals will have these...
I say go for Dunlop LM701s.....
