I have been a long time drooler over the LC and am finally considering taking the plunge on an '05. I have always like the looks and tire options that the 16" wheels provided, but now see that 18" wheels are now standard. Can someone advise as to the perceived advantages of 18" over the past 16" or is it soley cosmetic? If soley cosmetic, does this compromise the LC's longstanding off-road capabilities and will I be limited with future tire options? Reading some of the posts in the tire thread below make me a bit nervous that traction afforded by many 275/60/18s may be a concern in inclement weather, etc. The last thing I want is limited traction in a $55K vehicle known for its off road abilities.
