I won't be using these wheels since I sold them last night and am shipping them out tomorrow. I quickly fabbed up some spacers so I could see how they fit before I lost my chance. FFR told me that forgestar doesn't make a size that fits the 818. Instead of finding a matching front wheel, I decided to get all new wheels. Made out $50 ahead on the wheels, but lost $130 to shipping, but I don't need to strip and powdercoat the wheels I want and they're $300 cheaper a set so overall....I'm ahead (actually back on budget, lol).

18x9.5 + 48. Took 1/2" worth of spacers to clear all the suspension. You could go a little less, but not much. I only had 2 x .25" spacers for my test fit. Side panel was spaced to 13" from the shock eyelet as shown in the manual. I didn't do an alignment either, just how things were slapped together.

No guarantees from me, but it looks like with a narrower tire (ie, not a 295 that could fit, but a more conservative 255) it would fit.
