Hey all, new 2004 xB owner here, rolling on studded snows till Spring. (the xb rips through snow with these)

Anyway, I started my shopping for summer wheels, and found some 18 Enkei's with tires for a good price. With a 45 offset, not sure if they'll fit. Here are the full specs:

225/40/18

18 x 7.5 with a 45 mm offset

and obviously, a 4 x 100 mm lug pattern.

I understand I may need a spacer, but will that do the trick? Any thoughts are appreciated, I'm a dullard when it comes to wheels.

 

If your at stock height the 40's will work but if you drop it any they will rub. Most use 35's on eighteens to clear if dropped. An 8 inch wide +40 wont clear control arm nub in rear, a 71/2 +45 sits back the same distance you will need at least 5mm spacer in rear to fit. a +35 would sit more flush to fender and not needa spacer
Fronts should be fine +40 or +35.
Here is a good site to compare wheel specs
