rims prices are very competitive now. u can get reasonably
priced rims but its the tyres that you won't want them to con u
into it. there ain't cheap & good tyres, and also the
'workmanship'.
just a side
note:
do note that every rims do comes with a rubber bushing, make sure
when changing rims, the 'installer' do not mistakening left the old
bushing on your wheel hubs. please check. if a case of 'double
bushing' the rims, the rims will be unstable (either toeing-in/out
or -ve/+ve cambered) and it may just break loose one day.
therefore not just cheap rims, but good tyres and reliable tyre
man.. just my 2-cents
