W.S.
Bro, I would suggest following (in preference):
- Michelin
- Pirelli
- Bridgestone
- Continental
- Yokohama
Then in these tyre brands, there are different series, like sports, performance, budget, fuel efficiency, etc. etc. First select a brand, and then decide, which series to go for depending on your requirements, like low rolling resistance tires for fuel efficiency, tires for good road grip and handling, etc.
Still... to give some options, I would suggest to go for either Michelin energy saver series or Bridgestone Ecopia series. These 02 are low rolling resistance tires series, best suited for fuel economy. Continental & Yokohama are also good, but Michelin is much much better. Pirelli are quite expensive.
For shops; if you wanna buy non-smuggled ones, with proper import and warranty, and complete satisfaction, then look for No place other than Tire Point, Metro. Otherwise, for smuggled ones, the market is open to all sorts of offers.
If you would like to buy from authorised dealers of Michelin, Yokohama or Bridgestone, etc. Then best thing would be to call them (their contact details are easily available on internet), ask for their authorised dealers, get idea about prices, and most importantly, ask them to how to check that whether tire is smuggled or not? They will be happy to guide and assist you.
Zafar Enterprises, Pakistan Rubber and Tire Company, Tire Point (at various Metro outlets throughout Pakistan) and Sheikh Brothers, are official, sole, and authorised importers of Michelin, Bridgestone, Continental and Yokohama Passenger cars tires in Pakistan, respectively.
You can Google and get their contact details.
For size, it's up to you and your choice that whether you would like to go for upsizing, or stick with the stock size, or otherwise, etc. Still, I would recommend to stick with the stock, OEM recommended size.
If you would like to increase the width, i.e. 195 Vs 205, then slightly decrease the sidewall, so that overall dia. remains the same.
I hope, this all helps. Thank you.
