@imtishal:
I've been seeing Apollo AMAZER XL in 145R12 size for the last 4 years on different mehrans. Maybe those aren't available in Isloo.
Anyhow I'll recommend any Thai/Malai/Chinese brand if you don't exceed 110kph, which ppl in Pakistan don't usually do.
(Yesterday saw a civic w/ ZR rubber. OMG even if you can take a civic to above 249kph, where will you find a road for it.)
And don't go for India. Its not hate politics but if we'd so much like to support their industry, why in the first place we did demand independence?
