Hi,

I have the 22" PVD wheel with lowish profile tires on my 2016. Both are original equipment. Ford has already 3 wheels under warranty for peeling chrome. My warranty has run out. I know they will peel again and I will have to replace these wheels. When this day comes I thought I might get a smaller diameter wheel and a taller sidewall tire in hopes it give a less harsh ride.

My question- I will try to keep the circumference of the new tire/wheel combo the same, but if it is not is there a setting that can be changed somewhere that will keep the speedo accurate?

 

Yes using Forscan. Or buying a dedicated unit. Or buying a tuner.

You can generally get a tire/wheel combination that is really really close to the same as what you are starting with, then avoid having to reprogram anything. We're exploring a little bit of this type of thing in: https://www.ford-trucks.com/forums/1...a-limited.html

 

So I take it from the responses that there is no hidden setting screen in my Sync 3 that allows you to alter the speedo readout based on the circumference of the tire. No problem. I see from your replies it should be too difficult to come up with a combination that will replicate my current setup.

May I ask?
I stated I found the ride "rough" or "harsh". I am comparing that with my 2002 F-150. I really liked the ride of that truck. There are two major aspects of this 2016 truck I can think that would make it ride rougher; lower tire sidewall height, max tow package suspension. Based on your experience do you think I am on the right track?

 

BTW- I made a mistake. My wheels are actually the 20" chrome PVD wheels.

 

There is nothing in the stock console that allows you to "fix" the circumference of your tires. People will generally use a tool like ForScan to edit the tire circumference.

Those 20" wheels/tires have the shortest sidewalls of all the various options, and will ride the roughest. Going to 18" wheels and tires with taller sidewalls can make a big difference in the ride quality. The max tow and/or heavy duty payload package will also make a difference. A Lariat (I don't think) can be gotten with heavy duty payload.

 

I did not see anything on the window sticker about heavy duty payload. Just Max Tow package. Seems the tire change will be the easiest. I will live with the ride until the wheel really look bad and tires need changing.

Thank you all for your help !

 

I agree, more sidewall and less wheel makes for a smoother ride pretty much regardless of the other suspension parts. It's all relative though. Going to an 18 will take the edge off, but won't make it ride like an LTD.

The aluminum body doesn't help though. Less weight to push down against a bump when the suspension is being pushed up will do that. I'm not sure if Ford changed the spring rates much when they changed to the aluminum body.

I know what you mean with your 2002, those rode less harshly (in my opinion) than the new ones.

 

IMO more sidewall equals a bouncier ride with less control in the curves. I went from the stock tires and wheels to stock wheels with LT275/70R18's and the ride was less comfortable and the handling went to s....t. I then went with a 20" Platinum wheel with P275/60R20's and I now have a nice comfortable quiet ride with much better handling.

 

I think it all a matter of taste. Prior to this all my trucks had standard truck tires with higher sidewalls. From the first time I got in this truck I noticed the harshness over bumps. It actually rattles the passenger seat when empty. I also agree with a previous poster that this is where the lighter weight of the truck may not help either.
