Yes Michelin is the best. I recently bought XM2+ 42week2020 thailand made for 15k per tyre from an official dealer in RWP. My old michelin tyres were also adjusted for good rate.
My guess is you should be able to get it for 14.5-15k. Call the official dealers or better yet go to them and break a deal.
Also when buying new tyres, do ask them if price include nozzles and fitting etc. Try to get nozzles, fitting and balancing in same price (weight charges you will have to pay)
The official importer for Michelin is Zafar enterprise, follow link below to find authorized dealers. Price difference is usually 500-1000 so bargain with all of em and see which one gives you the cheapest. Take note they might also have smuggled tyres so go only for imported ones.
