All seasons are designed to operate ok in all conditions, which means they work great in none. Its a compromised tire off the shelf. You let them sit, or put it out in a change in environment/roads and run a semi aggressive/sport camber in the rear ie -2.5 removing 2" or better of contact patch and its not surprising what you are experiencing. Just drive the car accordingly to expect the rear loss of traction, or back off the camber, run a little less tire pressure maybe and or run a better tire. Sumitomos are totally budget and throwing the all season factor on there just compounds things for the worse. This car is really sensitive to tires and alignment man.

 

I don't disagree however I just find it strange its happened 2-3 times in 2 months, I've run these tires for a year and half without it happening once. Alignment is as its always been, rear camber bolts have been seized for over a year now and cutting them out is a massive pain.

 

what is the toe setting for the rear.

if you really think it's unusual, then i would suspect the front sway.

maybe something in your rear suspension is stuck, like shocks stuck and won't compress?

 

How low do the Swift springs lower the rears? I'm guessing it could be an experience you just had from the combo of road consistency and construction as well as the lack of travel on your rear dampers due to the springs. In other words, you may have taken some bumpy turns and the damper/spring combo couldn't accommodate and kind of skipped over the road irregularities causing the rear end to kick out. Might also be a toe issue, too. Hard to say.

The rear suspension travel is already minimal stock, I'm sure the springs aren't really helping to give you more.

 

Good point. If the rear bump stops weren't trimmed when the springs installed, riding bump stops explains a lot.

 

Yeah, but those swifts didn't make the car oversteer in VA.

Its probs them cool cool desert roads.

 

In VA the car understeers. In TX it oversteers. Somewhere in mid-TN it handles neutral. Move to TN, problem solved.

 

This logic seems irrefutable...

 

I dont know how I didn't realize it. Calling Uhaul now!

 

Obviously there are magnets mounted in this car
