2007 Jeep Commander. In town or highway driving I will get a bumpy ride as if all 4 tires are going flat. I stop the car along the hywy or side of the road then begin driving and the bumpiness is gone. Or if I continue driving. I get this burning smell and pull over then begin to drive and the smell is gone.
Feel each tires with your hands.Any high and low spots on the treads?
Never run your hand across the tread of the tire if you can’t see the entire tread.
Worn tires can expose steel belts which turn into hundreds of small needles.
Rub you fingers/hand across those, and your fingers/hand will get all cut up.
And you’ll only do it once.
