Guys, I'd like to share my recent experience. 185 65 R15 and 185 60 R15 only have a 9mm (less than 1cm) difference, I doubt it will ever eat through the fender guard.
However, after extensive research and going through all market options from Yokos, Dunlop to options like Nexen, Kumho, Continental and excluding Value based Chinese Brands, I decided to experiment with local General Tyres because of the price difference.
The 4 tyres of BG Tracko Plus of General Tyres Pakistan came for a whooping Rs. 22,000 after adjusting old Yokos (which at the time were available @Rs.16,500/tyre from company outlet). BG Trako plus is the same tyre that's now the default in Toyota Yaris. The advantage was that the default profile of Swift (185 60 R15) is available in it.
After driving them 3,500km, I can say for sure that I found them comparable in road noise to Yoko DBs that I took off, and better road grip and comfort than the old Yokos. The experiment was worth every penny, the tyres I got were manufactured 2 weeks old and I'm sure even if they last 40,000km they would turn out half as cheap as Continental or Yokos with equal utility.
So, if you can experiment with Made in Pakistan, I would highly recommend General Tyres for this instance. (I got mine from AR Dynamics, Sadi Road, Saddar, would recommend the seller to educated buyers)
