tire scrub

[15silver]

got new wheels with stock tires

 

did the rough country 2" leveling kit, and had it re-aligned. Got it back and drove it a week before checking tire pressure, and found dealer had left it at 25psi.

 

Up till this point I never experienced anything other than smooth turning.

 

Adjusted tire pressure to 35 as per the door label. When making hard turns for parking, I notice the front tires being rough/scraping in the turn now.

 

So - is this normal - happens to others & i just never noticed it before?, or should I go back to the dealer.

 

about 10psi difference, with the alignment done at 25psi - could this affect the alignment with the tires being low?

what is the backspace on the wheels?

close to stock offset/backspace. I chose these rims as the manufacturer has different offsets for the same wheels depending on stock swap, or eg - lifted and need clearance for taller tires. However - rim is 1/2" wider than stock.

 

Doing some reading (not specific to this vehicle), and its normal esp for wider tires (eg vette). Haven't had it before, and mostly concerned doing the alignment with tires 10PSI low may have thrown the setup. Wider tires have a greater differential in speed between inner and outer sidewalls on sharp radius turns, as the outside travels further.

 

Also reading on alignment, and its done to the wheel, so tire inflation may not be an issue. Uneven inflation L-R might affect it, but mine were all low the same amount.

 

Curious what other's experience is. The sound is very apparent.

 

Funny I didnt notice tight turns scrubbing before the level kit and alignment.
