Tramlining concern?

[S550HPP]

Pirelli P Zero Nero 255/40 ZR 19 96W M+S I think these are the stock ones??

Those would be stock. No one buys them to replace worn ones. Should be no tramlining with them unless they are at 5/32 or less. Pressure?

They are about 4/32 to 5/32 currently. Agreed, I'm not happy at all with these stock tires, they could give them to me and would say no thank you, lol.
Pressure: I've tried higher pressures but it doesn't seem to help. I like running higher pressure for stability and no tire scrubbing on corners (Old school from my autocross days). Been running 35 maybe i should try recommended of 32 or 30 even???

These Mustangs do that a lot.

Okay that makes me feel better. Haven't had this Gen 6 for long. The good news on my Gen 7 with Continental stock tires I have no tramlining at all. The steering is night and day, very light almost too light. So somewhere in between would have been nice, lol.

I’ve had 3 different sets of summer tires in size 265 35/20 and they all tram. Those big center ribs will grab pretty aggressively if the overlap is right. Stock pirellis, Yokohamas, and Nittos. So far the Nittos are the worst. Other than being ice skates the pirellis were ok when they got warm. But anything other than hot they were slippery.

Gotcha. So Michelin p4s4 or maybe continental??
Or is it just the geometry of the S550 that is going to dictate tram lining no matter tire choice?

many, including myself report no tram lining. alignment and tires do matter.

If you’re running a wide (greater than 8”) summer tire with a fat center rib, you’ll always tram on big seams in the road. Brand doesn’t matter.

I m running 305 s front and rear, Michelin PS4S stock tire. Dead straight, doesn t move.

Same ^^^. Mine did horribly with Cup 2's, but I went with PS4S and got an alignment (toe was out front and rear) and mine drives straight and true now. 305 front 315 rear, no issues...

I went from 305 Sport Cup 2 to 305 Continental Extreme Contact 2 with an alignment and the tram lining went away.
Find a really good alignment, brake, and tire shop and get new tires and an alignment. it's worth the money.

What’s your camber setting? I have mine pretty dead nuts center just about -0.8 +- 0.1 . Same with toe. It doesn’t tram all the time, just gets grabby on the asphalt sections butted up.

I ran almost -3 degrees on my GTI and never had any of the same driving characteristics. Those were a 225 45/18 on a 7.5 wide wheel. Different car and all that but they weighed within 400lbs of each other.

not sure, I ve never done it. Just got the car at 18K miles.

I’ve never run the MPS4S, but maybe they’re a less aggressive tread pattern. Maybe you have better roads too. But these cars will tug a bit, especially if it crowns on the abutment. I can’t say I’ve had it happen on a stripe, but these cars tram under certain circumstances. Like I said, it isn’t all the time.

It’ll bite eventually.

This. Tires is a huge factor. Wide tires and wide and sticky tires will accentuate it.
