Ya still using stock tire. Actually our stock tire is not that bad, after all it a Toyo, only thing is, it not a comfort and quite a noisy tire. 
iagree.
i aso heard that Toyo is not bad but to use in Msia highway which is very rough, scare Toyo cannot tahan the heat if we drive 300km (all the way to KL fr jb 2nd link), scare tyre pecah!
Along the highway, u can see some sisa-sisa tyres on the road right? That's the one!!!
Noisy, i aso agree with u. + the road quality!
