Re: 19" or 18" rims? Which tyres?

Bros,
Took the plunge on 19" with PSS at Ah Yang's. Gave it a few weeks to get used to it. Found it quite bumpy...thinking of going back to 18"!!
Would reducing tire pressure be the next best thing? What's the minimum pressure for 19" before I get weird wear patterns?
Anyone with similar experience and went back to 18" or once a 19 incher, always one?
Thanks hor...so pek chek!!
Such an experience is not common until you know what you are looking for...
Let me help to point out several contrasting requirements without bringing in the "look good" factor which is all up to one's taste...
1. Your previous setup of rims and tires was not mentioned. This will give others a benchmark to judge the entire unsprung mass of the rim+tire. The brand&model of the tire will also play an important role as that will determine the high frequency low amplitude (like going over the lazy policeman strips before some ride of the humps) performance. It is primarily the tire that absorbs these shocks.
2. Your present setup of which rim and which tyres. We know thetire brand and model but what if its a 7 series that has no diff between that 1" growth.
3. Your suspension and its age. Cos the type of suspension will determine the spring rates and that is the primary factor in determining how the car rides. All lowered springs will be harder than stock to prevent your car from bottoming out. Its the job of the dampers to control those springs. How many people have installed lowering spring just to get that look? As the dampers matched? Age of the dampers also play a very big part. We have seen many many cars here with leaking dampers and broken bump stops. Go figure...
4. If comfort was your top priority, then choosing a more comfort orientated tire could perhaps claim back some of low speed bump performance that you so desire.
I think what you want is the holy grail....The tire that grips in the dry and wet, is so quiet that babies just fall asleep in the car, has braking performance that stops without the ABS kicking in, is made of space age materials that allow it to last forever and yet weigh in at less than an F1 tire and on top of that cheap as hell.. ha ha... don't we all want that.
Please pardon my ranting but take pride in the fact that you achieved probably the most important factors above (according to my own opinion) for grip, handling and performance. Just remember all that is keeping you on the road is 4 pcs of rubber, that has a total surface area of about 1 sheet of A4 paper, generating the friction.
cheers
