Congratulations!
Welcome to The PAJERO GENERATION 1 CLUB, to be precise
Don't change those Genuine Japanese STEEL Rims.
Advantages:
Very Tuff esp. for off-roading,jumps,hops
long lasting, durable, fixable, un-breakable, re-paintable anytime
Dis-advantage:
little heavy 20 pounds max each.(but in-fact nothing for suv like gen 1 pajero)
slight hardness on cornering
slight slow pick(acceleration) to re-gain momentum(this thing eats fuel)
---make sure all ur 6 Lug NUTS are superior quality! Tuff n TIGHT !
Its' easy to sell those rims off, but very HARD to re-possess them back at low cost
I'm using Good year H/T 225/70r16 Wrangler on those rims, with usually 33-35 psi on all 4 tyres. On & Off road, both very strong n easy! STEEL Rim is usually a tension free thing for me, cause i dont want my SUV esp Pajero giving small-filthy troubles like cars do, i want it Tension FREE! Hop n Ride Ranger all da time !!! :D, all u have to FIT is ur tyres shud be GOOD & NEW
Re-check ur front suspension for over-haul, Get the Double wishbones fixed n corrected, pressed, shocks, steering damper, ball joints, bearings and bushes etc.
