I have gone to batangas (via tagaytay) with my car... I ride on 195/50/15 tires at that time. No problems. But you have to be aware of rocks and other stuff on the road all the way and back.
i have a 195/45 R14. nadaan ko na sa mga kalye na malubak at mga unpave road with loose rock/soil (at madalas). Matagtag and its very uncomfortable. parang nakakawawa ang kotse. last tuesday night sumabog yung isa, nabiktima ako ng "squaring" ng DPWH dyan sa sucat
currently using 215 x 35 x18. Tagaytay/Batangas no problem. I use my stock mags and tires when I go up North because the roads are bad up there compared to the south.

I used to have 205/45/16s.... I drove them for 2 years... Grabe ako amgdrive and whenever i get home i'd do a visual inspection of the outer rims. I say to myself..."grabe ang tibay naman ng rims ko" then when the time came to replace my kalbo tires and they pulled out my rims i saw 9 bengkongs all on the inside! 3 each infront and 2 each at the back! and prior to that day i came from sta rosa and hit a lubak pretty hard. i checked the rims as usual and had a big one on the outside. i thought it was the only one i had so i was gonna have it repaired same time i change my tires... but oh well i didn't know what i had coming LOL. i traded in the rims and got my self 195/55/15s now LMAO!
