We bought our PC brand new over 10 years ago. It has those flexible braided extenders attached to the center hubs. The rig has around 37,000 miles on it today. I have not yet disturbed anything with the tires, extenders, or wheel covers, untouched since Phoenix sold the rig to us. I have never had an issue with a leak, but I fear any disturbance will yield in extender leakage and then wheel cover removal.
I had looked into replacing 4 of the 6 steel wheels with Alcoa alloy wheels when it comes time to replace the tires. Here were some of the part numbers I found some years ago.
160241 - front wheels polished/finished for front mount
160242 - rear wheels polished/finished for rear mount
?????? - front center hub cap
?????? - rear center hub cap
190 - lug cap x32
13/99/87 - the lugs that accept the caps (I think we have these already)
I recalled locating a company in the south (maybe Alabama) that sold them so much cheaper than everyone else, including shipping. I wish I kept that information. Just now I just googled "Alcoa Wheels E350" and found
THIS RetailerYou don't want to replace the inside rear wheels from steel to alloy because the rear axle lug stems on the E350/E450 are not long enough for the extra thickness of the Alcoa wheel x2.
Of coarse having Alcoa wheels eliminates tire rotation. I would never rotate our tires anyway so that works for me.
I've seen high-end motor homes sold with Alcoa wheels and they really look sharp. Our PC would look so much better with them. It would be the perfect time, replacing tires and wheels together like that. I'd then sell my old wheels and tires mounted on them, on Craigslist to recover some of the cost. A local landscaper in my community running around with older-yet bald tires and bent & rusted wheels on his truck would surely be interested in them. He can swap them himself on his driveway, keeping his costs lower yet.
Our wheel covers untouched for the past 10+ years.
