hey just wondering if 18" rims will fit on my 91 liberty?? ive been told 17" will fit easy but not sure of 18"s??

What rim width and what offset are the 18s? If you are in NSW be aware that you can't change the wheeltrack by more than 25mm over standard legally (doesn't stop a lot of people doing it though).

Really depends also on what tyres you will run on the rims. The correctest size would be a 225/40R18 but 215/45R18 is more common. I've spoken to a number of people who done 18s have gone back to 17s as the ride was too harsh.

Often the best way to do it is to trial fit the wheel & tire combo. If it fits on the rear, then go for the front, remember to test on full wheel lock both directions and under suspension load to see if it scrubs/hits anything.

This is quite handy: http://www.superjamie.net/garage/tire.xls

Not worth the headache mate... Due experience and seen other people and you will need engineer's cert and larger brakes before adding 18"
Depends what liberty you have, if you have gen 1 or 2 Lib the factory was 15" hence you can go 2 inches or under you won't have any problems, if its over 2inches then you'll come into problems..

depends on offset. Is the car lowered? you may have to get the guards rolled to prevent scrubbing, and maybe abit of negative camber thrown in for good luck.

the rears on my gen3 scrub when theres more than 2 people in the car. Especially when cornering hard obviously. Im running 17's and low king springs.
