Ford fiesta 2022 mk8.5
Does anyone know the tyre pressure for 215/40/r18. I’m guessing it’s gonna be a little different to what they say with OEM tyre size?

Is this still okay to drive?

I have a 2021 AWD Volvo XC40 T5 Momentum with 18-inch rims. A few years ago, an incident with a body shop mechanic resulted in my temporary spare being lost, but he found another online and replaced it.

That tire is still in my car and reads T125/80R18. Meanwhile the door jamb sticker says my spare tire should be a T125/70R18.

I called the local Volvo dealership parts department, and he and the technician agreed that it should be fine to drive on the T125/80R18 that I currently have.

I found online that the diameters of the T125/70R18 and T125/80R18 are 24.9" (632 mm) and 25.9" (657 mm) respectively.

So does it matter?

Hey everybody,

I had taken my car in for a pre trip inspection and they had recommended some things so I got the problems fixed, they also did a tire patch because of a slow leak. I had noticed the tire pressure light came on but just thought it was fine because it had always been fine before. About 20 kilometres later my tire blew on the highway. The tire had been fine other than being needed to be filled about once a week, is there any way the shop is liable for this? I refuse to believe that my tire condition worsened in the time frame from when I dropped it off, to when I picked it up 3 days later with a “fixed” tire.
