I'm looking to replace my OEM Pirelli PZero runflats with a non-runflat.

I noticed this new tire design and the price seems good. No reviews.
Do you think I could get away with a wider front/rear tire on the stock wheels?

--Current setup--
Non-ZTK
OEM 791M wheels = 8" front, 8.5" rear width
OEM Pirelli PZero runflat = 225/40R19, 255/35R19

--New tires--
Vredestein ULTRAC PRO = 235/40ZR19, 265/35ZR19

The Vredestein SPEC section says the rear 265 tire needs 9" rear wheel width. Will this work with 8.5"?

Additionally, what's the spacer setup for non-ztk? 12mm/10mm F/R?

Thanks everyone.

Stretching a tire "can" lead to rapid degradation, it all depends on how hard you drive. If you drive like a grandma then you should be ok, I personally wouldn't risk it.

I'm facing the same dilemma, I want more tread on the ground, but not ready to burn $3-4K for rubber on a brand new car.

As for spacers, I just ordered 12mm Front, 15mm Rear. Waiting on Dinan to get the 15mm's in stock. Also make sure whatever size, you get correct length lugnuts.

What's your current tire/wheel setup? Most of the spacers I would buy come with extended lugs, so should be good.

I have the factory 19" wheels, I believe 225F 255R.
