I just changed tyres on my Pajero Sport, so took me few days to find the good deal. First of all buy tyres that only few months old, means 2024. The difference between different shops/online is about 500-1000 baht per tyre max, everything else is scam. Michelin/Bridgestone is the most expensive, you dont need em anyway. Look for Yokohama/Goodyear/Dunlop for 4500-5000 baht per tyre(in your case it can be cheaper cause yours are smaller). If you want a bit cheaper Maxxis are good choice, can have em for 3800 or even less. Myself i found discounted deal on BFGoodrich Advantage Touring for 15K instead of 20K at Tyre Plus. Very happy with those tyres, feels better than GoodYears that I had before.
