My bad. I didn’t put the sidewall ratio in my post re: “295/20’s” because it was late, and I couldn’t remember if it was 30 or 35 sidewall that was closest to the original DH HP rear tire diameter. Sorry for the confusion. Made the change to 20’s because I wanted a black wheel instead of Dark...
I’m thinking of going with 295/20’s for my rears. My 305/35/20’s affect my speedometer.
1 Is your speedometer affected?
2 How well do they fit inside the fenders - outside, even, inside?
I know others in this forum will recognize that I’m being repetitive, BUT, it needs to be pointed out that it’s not just the #’s on the side of the tire that matters. You have to take into consideration the tire structure as well. The Pirelli Trofeo RS has a curved side wall that results in the...
That’s the part that doesn’t fit. It took 4,000 miles before I had a problem. Why not right away? Why isn’t anyone else having this problem? I’m just happy to have it back right again.
Funny thing. I spent months gathering info before I changed tires/wheels. Read the Forum entries. Looked at numerous wheel makers products. Actually drew wheel & tire dimensions to scale on paper. Saw nothing like this problem anywhere. And, I still bought the wrong setup. No more mods for me...
Stock tires/wheels in place. System re-aligned. Problem solved. Adaptive & normal cruise control working. Dealer was awesome. Only charged labor for exchanging wheels. Since I had a replace CCM code, warranty covered the rest -$1,000. Now I’ll probably change the front tires on the Ferrada...
Thanks Skye for the advice & the tire comparison tool. I responded earlier but didn’t hit post. Took wheels to dealer today. Spoke with mechanic. Says there is a “SSM” about it. Pretty sure it’s the new tires being too tall. Says the camera in the windshield has to see the road to gather data...
I’m sorry if I’m over-posting or posting in the wrong place but i could really use some input. I posted in another location earlier today & got no response. Have meeting with dealer today.
Error message that pre-collision assist & adaptive cruise control not available. Can’t switch to normal...
Update. Dealer installed new CCM. Problem not resolved. Now they’re telling me me it because of my new 20” wheels & tires that I put on 4 months ago & that I have to put the original 19” setup back on. WTF! Does that make sense to anyone? I see lots of people changing wheels & tires on this...
I have Gorilla small diameter spline duplex lug nuts (short on front, regular size on rear) on Ferrada CM2 20” wheels. I texted Ferrada & Gorilla today. Ferrada says follow manufacturer’s specs (not sure if they mean Ford or Gorilla). Gorilla says 100-110 ft-lbs. I’m currently at 150 per Ford...
It is a speed limiter. I’ve tried using it lately while I wait for parts to fix my adaptive cruise control. When set to a specific speed, once you get to that speed, further small depressions of the gas pedal will not increase your speed, unless you depress the pedal a significant amount. Then...
I have this problem now. Also pre-collision assst not available. Dealer found codes for cruise control module (CCM) & tried to do a driving CCM “alignment”. Failed twice. CCM ordered. Follow up appointment in 2 weeks.
I just test fitted my Automotive Authority spare ($459.99) on my 2024 DH. Since I have changed to 20” wheels with Michelin 305/35/20 A/S rear & 285/35/20 A/S tires, the spare is slightly shorter than my rear tire - 3/8-1/2”. Front pretty even. Does anyone think the rear height difference will...
I’ve had this happen periodically on my 2020 Explorer ST (Sync3) It has always cleared with next start up. Also now having trouble with my 2024 DH re no adaptive cruise control or crash assistance. Can’t even get normal cruise control when I turn adaptive cruise off in Settings. Dealer checkup...
Compared to Escort radar detector with GPS speedometer.
DH reading lower than actual speed per GPS
DH 30 mph ——-GPS 32
DH 50 mph ——-GPS 55
DH 65 mph ——-GPS 72
Faster I go, more DH is off
I ordered one from Automotive Authority$459.99. I haven’t taken it out of the box yet. Don’t know if it will fit front & rear or in the spare tire well. I also carry the slime until I figure it out.
That’s difficult to answer definitively since there are different levels/stages of Roush Mustangs that include different suspension mods & different output level superchargers. Just as there are different non-Roush Mustangs (GT, DH, Shelby, Handling Package, PP, etc. Mine had 710 hp & I think it...
