My original Continentals had been doing well up until recently when I started to feel a wiggle going down the road.
The rear tires had started wearing a little oddly, figured this was the cause, front tires looked nearly perfect with very low wear.
So, I hadn't had the tires rebalanced or rotated since I got the truck, and it had 37K miles on it.
Took it to my buddy's tire shop and had them do a balance and rotation.
They had a hell of a time getting those oddly worn rear tires balanced, was taking lots of weight, so they broke them down and turned them 180* and rebalanced, still took some work to get them done.
So, went out on a job this past weekend and now after the rotation the front end was having some wiggle from those oddly worn tires.

So, I'm going to give up on those tires, think they are bad, and due to the miles I don't think Ford isn't going to warranty them.

Anyway, I had great luck with the General Grabber HTS60's I ran on my RAM, so I decided to find some of those.
I also decided to step up the size from 275/65/18 to 275/70/18 which is the size my RAM used, and the slightly taller tires have a higher load capacity.
Well, those General Grabbers seem to be in short supply, sort of like many other things lately, but I finally found a set, and am getting their last set at a decent discount.
Now, my speedo with my original tires reads faster than the actual speed, the new tires should make the truck run faster than the speed shown on the speedo, so somewhere in the middle should be where it would be accurate.
That will leave me to figure out how to get the speedo reset.
Have they figured out how to use the forscan on the 2022 trucks to correct the speedo yet???

 

Dealer can do this for you as 275/70R18 is a factory tire size option on the Superduty. If your speedo is already running fast this bump in size may just correct you.

I dont run 285/70R18 tires but every Superduty ive had since my 2013, the speedometer has been fast and the 33" tire size has been what corrects it. Seems the factory calibration is default to that size at least on every truck ive had.

 

Lots of trucks here, local tire shop manager told me to stick with either 275/70/18’s or 295/70/18’s because they are common sizes and easy to find.

 

Regardless of size, you need to rotate your tires properly so the same issue doesn't arise again.

 

I don't think the tire issue had anything to do with whether they were rotated or not, I think the tires were bad from the beginning.
I never did the old standard rotation on the tires on my RAM, never had any such issue.

 

speedo difference is going to be negligible from that tire size change. My 35's are accurate still based off my speedo and the radar BS on the sides of the road.

 

That is going from a 32" tall tire to a 33" tall tire. You should make an adjustment. It is pretty easy to do in ForScan. I have mine set within 0.5 mph of gps and went from 275/65-18 to 285/75-18. I think the guys not having luck with this adjustment in ForScan were trying to adjust for 37" tall tires.

 

I plan to check the speedo error after the tire change, before making any moves to adjust it.
Since the speedo is off already, it may be close enough after the tire size change.

 

I ran that size on a 2wd and thought they looked too tall. Switched to 285/65/18s, same load rating as the 275/70.


Also consider swapping in your spare tire and buying one. Save you 3 tires $$ for now.

 

I take it you're referring to me, I already bought the new 275/70's and they are only 1" taller, and I've had them before on my previous truck.
And, I also have a spare tire in that size from my RAM that I can replace my truck's spare with.

 

So, the new tires seem to have made the speedometer read slower than the indicated speed, it is running just a little more than 1 mph faster than the indicated speed when going 70 mph.
Going to ask the service writer at the dealer, when I go in for the trailer brake controller recall, if they will change the tire size in the computer for me.

 

If you never rotate your tires then you are only getting half life from them and you have no clue whether rotating would have stopped or prevented the abnormal wear pattern.

 

No, don't think so.
I didn't rotate the tires on my previous RAM and got 80-100K miles out of the them.
So, you are saying that had I rotated them, I could have gotten 160-200K miles out of them???
