Upgrading 19.5 to 22.5 Wheels on Ford F53

I am interested to learn how I can upgrade the 225/70R19.5 wheels on my 2012 Fleetwood on a 2011 Ford F53 chassis to 22.5. There was an older thread on someone who had done this but I can no longer reply there. I realize the speedometer will be off.

The question is: Can I just purchase Ford 22.5" steel wheels - the ones that come from the factory on 22.5" equipped F53 chassis models? Or do I need to go with American Force aluminum wheels and have the bolt pattern custom cut?

I suggest you ask Ford if the larger wheels are compatible with your chassis. The Ford website has a phone number for customer support. You may have to talk to a few different people before you reach someone knowledgeable enough to answer you question but it would be nice to know you have accurate info before spending a bunch of money.

Here's a link to the previous posts on the subject. The OP's site name is LVRVLUVR

https://www.irv2.com/forums/f23/am-i-...5s-278690.html

One thing the OP didn't address is the fact that the torque value on the 19.5" steel wheels is 150 ft. lbs. while the torque value for the 22.5" wheels is 450 ft. lbs. Also the lugs on the 19.5" hubs are smaller and would twist off at the higher torque. Another thing to consider is that the 19.5" wheels have a 10 lug design while the 22,5" wheels have an 8 lug design. Here's a link to the F53 brochure for 2014.

http://www.fleet.ford.com/resources/...2014_LoRes.pdf

Note the differences between the lighter and heavier chassis. The 22,000 lb. chassis comes standard with 8 hole 22.5" aluminum wheels, but can be ordered with 10 hole 19.5" steel wheels as an option

Keep in mind the OP seems to have an endless stream of money and claims to have owned over 60 motorhomes in the past few years. He is constantly "making improvements" on the Ford and other chassis. If you read through his 250 or so posts you'll see many of the "improvements" including the wheels had to be removed or redesigned several times. In his case the wheels were custom made.

Beside fitment issues you will certainly need to adress the gear ratio that is presently in your MH. Your overall tire diameter will increase by 5 1/2" when switching to the 22.5 wheels and the speedometer inaccuracy will be the least of your problem. A 5.5" increase in tire diameter will make your MH feel like you lost 100 hp, it will be very sluggish on take off and will not shift into high gear until speeds much faster than you want to travel and will likely downshift almost immediately. This change will net a 12 mph increase in speed compared to stock
