Found a Rickson estimate for the e450:

225/75R17.5 Toyo M143Z's load range "G" tires all the way around, cost about $3,200. includes mounting, harmonic balancing and shipping, also included an unmounted spare tire.

BTW on rv.net I found the following report, "I was able to get new wheels to allow for the correct offset and went to 235/85r16. They had 20% more weight capacity over all, istr. It slightly improved fuel economy and like you my "clock" is now wrong by similar amounts.

I had no blow outs but my tires had 66000 miles on them and were ten years old.

The extra height really helped with the tail dragging on ramps at gas stations. It is now a rare occurrence." [url]https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/26783432/srt/pa/pging/1/page/5.cfm [\url]
