Different types of tires make a huge difference. Michelin PSS likes to tramline a lot.
Not in my experience.

That's with three different sizes on two different cars, one set on max-width wheels, the other two on "measuring width" wheels. Two sets being run at close to -2° camber, one set around -0.5°.

I'd bet that OP's car would quiet down a bit if the front and rear toes were checked and reset to slightly less-aggressive values.


I do agree about tramlining being worse (sometimes much worse) with some tires and barely noticeable with others.

Tramlining in the GT350 as stock is less than it was in my '13 GT500... I mean way less.

To me is not an issue ?

I noticed the tramlining more especially when its on sport steering it dips into the grooves on the road and yanks the car and makes me fight the wheel

I didnt have this on my older GT, narrower tires

After i changed to 6G R spec wheels and Conti Contact DW tires it completely eliminated it.
Same here.

1st switched to the winter 295 square pirellis on stock rims 0 tramlining.
5-6 mos later popped on my new summer setup - 6GR R-specs w/conti dw summers and 0 tramling.

selling a set of four stock pirellis one tire has a nail in the middle thats an easy patch... pm a price

Not sure how accurate tire pressure sensors are however it showed all my tires even. I took her out for my weekly Sunday drive [sic]. Noticed it was tramming! It has never done this. So scroll through and find that all 4 tires are down 3# from my last recollection. I know temperature, its been steadily getting warmer, and car sits in a 40x80 closed metal barn. So do tires stretch when broken in? Anyway next Sunday they will get put back and then will see.

Not to my knowledge. But they aren't guaranteed to be 100.0000% airtight either.

Never mind that if your recollection was from after the tires had been warmed due to driving on them for a while, a 3 psi loss from there would be entirely likely.

For inflation pressures in the 30 - 40 psi range, the correlation between ambient temperature and inflation pressure is approximately 1 psi pressure change per 10°F temperature change.

My last alignment - before and after. Tramlining much improved after the alignment.
