Tires Firestone or Goodyear

The newer style Firestone WinterForce 2 are decent tires. Good tread design, not too hard, not too soft compound. Fairly priced $100-150/ea depending.

On a other note, the Indy 500s are a great tire. 90% of the grip of the Pilot Sports for a fraction of the price.

I have 205/50/16 Indy 500s on Dekagrams and it’s perfect. Have specR lowering springs also. And no rubbing (sits perfect to me).

I now have Firestone Indy 500s and am quite pleased with them.

Firestone indy 500. Rest of the world except usa they are known as bridgestone re003

fantastic tires. on my 3rd set on my z over the years. Great in the rain. good traction. not noisy. and affordable

Goodyear eagle ones on the factory 19s. Solid ride, comfortable, and plenty of traction

I've got Goodyear Reliant All-Seasons on mine currently. Got them for $62 a piece last Novermber, and have good luck with most Goodyear and Cooper tires.

If your car feels like it’s bouncing/bobbing sideways (I’m guessing that’s what you mean by “bubbling”), it’s probably due to the softer material used on the winter tires. I’m running a set of Goodyear Assurance WeatherReady and they show the same behavior. The effect will less noticeable eventually as the tire passes the break-in period.

I work at a dealership and I will say that I will never buy Goodyears, they dry rot faster than any tire I’ve seen

I had the Firestone Steeltex the ones before the Transforce with good tread They had less cracking than I see on yours. Drivers front blew out on the way home from vacation, 70 MPH and barely missing the concrete median. Personally I would replace them and personally I would not go with Firestone
