255 runflat on a 9.5inch rim possible??

Freestylerfalcon · 04-09-2018, 05:52 AM

Went in to tyre shop today hoping to get my stock runflat pzeros fitted from 403M 19x8 19x8.5 to my new GTC 19x8.5 19x9.5 wheels.

The shop said its 100% impossible to stretch the 255/35/19 runflat rears onto a 9.5 rim. Due to sidewall stiffness.

Is this legit??

Based on info on tirerack, P zero run flat 255/35/19 should fit on a 19x9.5 wheel.

There is little to no stretch with a 255 on a 9.5 wheel. I run this as a square setup and my fronts are run flats. You need to get a new tire shop...

I call it BS. I have 255/35R19 RFT in my 19" X 9.5"

Heck I even have my winter square tires on my OEM staggered so I has a 225 in a 8.5" those were hard but doable. they're just being lazy

As a reference 255mm is ~10" so yeah they should fit

Thanks for the feedback and pics guys.

I think they were trying to sell me a set of new tyres

Am going to a different shop

Interesting -you're running run-flats on the front and traditional tires on the rear? Different sidewall stiffness, braking coefficient and traction compounds front to rear. How does that handle??
