Rear tire size

[Andy Feuer]

Velgen VF5 with Nitto NT555 tires: 275/35/20 front (20x10), 305/30/20 rear (20x11).
The rear tires stick out ever so slightly. Does it get stuff on the rear panel? Sure does. Do I regret doing this? Not for a second.
The 305/30/20 are essentially identical to the stock tire size, so speedometer isn't an issue at all. If you go with 35's you will be off a 3-4 MPH at 65 MPH (and off more at higher speeds) unless you get the computer updated.

Does your cruise still work with that setup?

From Alibaba

It never occurred to me to check Alibaba for wheels. Just checked and these prices seem crazy, I’m intrigued. $250-300 for each forged wheel?!?! Are you in the US? How much were the wheels you settled on? How much were tarrif/import duties? Were yours listed as forged? And are they?

the price depends on what you will order
And yes they are forged
I don't live in the US it costs 1770$ to the door including shipping and they send a lower price Invoice when they ship so you don't have to pay more for taxes

I received the wheels a week or so ago but still waiting on the caps should arrive this week hopefully

It's a very easy Forscan fix to update the tire diameter.

the problem is the adaptive cruise control stops working when you change the tire size something to do with the radar angle

My adaptive still works with 275/35/20 and 305/35/20

I still don't think that is the issue... easy way to find out, just change the angle of the radar sensor...

I too have had no issues with similar sizes. Though I did change tire size (rev per mile) in the PCM so speedometer would be correct.

I didn't have them change anything in the PCM and it works perfect (at least with the size I went with.

Update on my 20” wheel/tire change & loss of pre-collision assist (PCA) & cruise control (CC) on my 2024 DH/HP.
quick recap: changed to Michelin PS4 all season 285/35/20 front 1.6” taller, 305/35/20 rear 1.9” taller>lost PCA/CC>couldn’t recalibrate>Ford said d/t altered camera angle>back to stock 19” Trofeos> recalibrated >changed 285/30/20 front 0.2” taller, same 305/35/20 rear 1.9” taller> lost PCA/CC.
Someone suggested I put the stock 19” ones on the back with the 0.2” taller 20” on front & see if it would recalibrate. IT DID! Great tip!
So, I’ll put the front stock 19” ones, run them until it gets cold & put all seasons on with new rear 20s that match the stock diameter. Probably will have to go to 295s. I don’t know how others are getting away with 315, 325/20 rears & not losing PCA/CC. Doesn’t compute. Thanks for putting up with my whining & for all the suggestions.
