Ha, Ha... When I test drove my new 2007 I think it had the same bling bling rims on it (I think it was the exact same wheel)... I asked about it and the salesmen remarked about how cool the look was and it was 'only' $3500. I laughed and told him if he would pay me the $3500 I'd consider keeping the tires and wheels.
I bought the runner that night and drove it off of the lot with the promise that they'd replace the wheels with stock the next day. I drove it that way and the ride was weird and had a bit of a stutter over sharp bumps. The ride with the stock 18" wheels and cross terains is much better, even with the pressure at 40 PSI. It's still a bit wallowy, but nothing I didn't expect on a 5k+ lb vehicle, and nothing stiffer springs cant fix.
The limiteds come with 18" wheels that don't have to be polished and are beter looking in my opinion. The ride improved quite a bit when they (reluctantly) put the stock wheels and tires on.
Bling like this is not worth it to me on a V8 4x4. I bought the runner to use it, not to polish it and parade around town.
Just my two cents,
Sean
