1. any changes on fuel consumption after changing the rims & tyres? my current driving pattern with stock wheels earn me an average fuel consumption of around 8.5L per 100km, mostly city drives without much jam..
fuel consumption will be higher.bigger tyre more heavy.but better dry traction and handling.
2. budget matter.. if i put a budget around RM6000, basically what type of rims and tyres can i get?
u can get a lot..265 tyre cost around rm 450-500 for branded tyres like bridgestone/maxxis a/t type.rim usually cost below rm 2000 for lenso.average imported rim are somewhere rm 1300 plus minus
3. usually i see most ppl who changes the wheels will lift up their ride by few inches, isit really necessary?
if u dont change oversize don't have to lift up.because oversize tyre caused rubbing when u turn your steering.unless for aesthetic purpose.some thinks lifting make car nicer.
4. can i just change the wheels and needless to lift up?
usually change 8-8.5j.but it also depend on yr car model and also rim and tyre spec

do u like black rims?haha..feel black rims looks very sporty on 4x4 and especially the new ford ranger.so garang
