Navigator and 28's?

[300CN24S]

Anyone know if 28 inch rims will fit on the newest model Navi (07 or 08) without major modifications. All I have been able to find are 6's. Any input would be greatly appreciated. Thanks.

Well the previous 28" tires were very thick (pretty much only made for hummers) but now they offer a 275 25 28. Not sure how it would ride, but it will definitely go on there now. I wouldnt think with that skinny of a tire that you would have to do much to it since the navi can hold regular sized 26's now (with the 305 tire)
