Should I be frustrated or am I wrong?

It seems that everyone who responded has forgotten what the Owners manual says. Please read under Tire Care page 345/346. I move mine side to side at every oil change and believe me the tires last a lot longer.

Does Rotating Tires Side To Side Help?

Some tire rotation is better than no tire rotation at all. When rotating tires from one side of your vehicle to the other at the same end, you don’t change the wear pattern very much.

Your left front tire and right front tire will wear very similarly. Switching these tires will even out inconsistencies in wear between the two sides but they will still wear very similarly.

For instance, rear wheel drive sports cars, which are a common type of vehicle to have a staggered wheel set that can only be rotated side to side.

These sports cars tend to have rear tires that wear more on their inner edges and very little on the outside. Rotating the rear tires from one side to the other will not change how much they wear on the outer edge versus inner edge.

Moving one tire from one side to the other will do little to move wear to the more unused side of the tire. You’re better off flipping the tire on the rim if you have the option. This will be extremely effective on a staggered tire vehicle.

Effects Of Rotating Tires Side To Side

• Helps even wear pattern inconsistencies between sides of the vehicle
• Isn’t much better than not rotating your tires at all
• Doesn’t shift the contact patch to less worn tread
• Directional tires can’t be rotated from one side to the other

Directional tires can not be rotated side to side. When a directional tire is mounted on the rim and put on one side or the other of your car or truck, it must stay on that side of the vehicle.

I have always been diligent about tire rotations. All 4 the same size non-directional, are of course easy standard rotation. All 4 the same size and directional, front to back rotation assuming the rears (at least in solid axle cars) will wear more in the center, and fronts more on the sides. Staggered and non-directional, the side to side is of little use... except perhaps if the car has a poor alignment, you may squeak out a few more miles. And staggered directional of course have to stay where they are... In fact, in some racing circles, they recommend to always put the same tire back in the same position, under the assumption that that tire has the optimum contact patch in that position, and you may experience loss of traction if rotating them (at least until you wear in a new contact patch).

Bottom line, I would not worry about side to side rotation... just make sure you get an alignment done as most of our S650's come with poor alignment from the factory... and ford will cover it in the first 12 months of ownership.

It might equalise life over the 4 tyres, meaning replacing 4 at once rather than 2 at a time, but not really extending life per se. On old crossply tyres with crappy suspension yes, but modern cars - not really.

If the car is aligned, camber close to zero, and you keep them rotated, all tires will outlast the milage rating. Been doing this as a profession most of my adult life and always get the 60k 70k on car and crossover tires. It is simple geometry. Yes, when suspension wears out and not serviced tires will be junk in a couple thousand miles.

Currently have over 7500 miles on these P zero DH tires and even minimal wear on all 4

That’s awesome.
Let’s see a 0-60 run on those tires.

Let's don't get too off base. Rotating was done in the old days (and still is) to even out tire wear. These days, with a lot of vehicles having limited slip technology, uneven rear tire wear isn't an issue. Newer suspensions with virtually no toe in or camber does the same for front tires.

We also need to remember that performance vehicles often have both staggered sizes and unidirectional designs. These 'features' make rotating impossible. They also add to the cost of ownership. Imagine having a Dark Horse with a Whipple, and then bitch about tire wear!

Hey I have a Dark Horse with a Whipple. But no one is going to take my God given right to complain about tire wear.

That type of driving is what the "Track Attack" was for, beat on those FPRS cars. My ride is driven like and by "an old man" my car has not ever seen 3,500 RPM's under my watch.

First off: No judgment, implied or stated. Your car, your rules.

I would maintain that at that ... August mileage, those stock Trofeos are practically heat cycled to death and I would seriously question your ability to do really fast stop, not just a really fast take off.

They’re fantastic tires, I loved them for about 1600 miles. The last 500 miles I was definitely on eggshells.

Lastly, you don’t get to be an old man for nothing, so !

I'm not familiar with the Pirellis. Some brands continue to use arrows. Others, if directional, will have the words "inside" or "outside" somewhere along the sidewall, the "outside" being street-side.

If a staggered setup, moving from side-to-side would provide zero benefit. In your situation, I'd do what others with staggered setups do: leave them where they are at.

While the tires cannot be rotated, the mechanics could be asked to re-torque the lugs. Using a torque wrench, not an impact gun set to the highest setting. And, confirm air pressures.

It would be a good practice to check the tread depth every so often with a gauge, all tires, to confirm they are wearing as expected. I check mine once a quarter with a Milton tread depth gauge.

Thank you.

Because you have the performance package, your rear tires are a size larger than the front tires (Staggered sizes) which is why they don't move front to back and back to front.

I know they don't move front to back, but was curious about side to side. I don't notice any arrows or markings indicating unidirectional. Thanks though.

The braking on the car is still really amazing, have not to this point see any reduction. I will take tread measurements tomorrow, I will bet they are still like 7/32" plus at the lowest spot.

 

[LouG]

Tyre rotation is well worth doing if a car puts heavy wear on front or rear tyres. High power FWD's for one example.
I'm not so sure about swapping side to side though, I'd measure the tread depth then make the call.
As someone posted, I'd keep an eye on unusual wear patterns and get an alignment if needed.

This is 100% wrong, please disregard. Rotating tires prolongs life a ton.

Absolutely! I can not believe the positive impact on tire life for this simple procedure.
