Odd tyre sizes

nusya · 11-19-2023, 09:08 AM

Hi, I have an 5 series f11. We were travelling home when we got a blow out on one of the rear tyres. The only replacement we could get was a 245/55R18 while the other router login 192.168.l.l.link/ that's still on the car is 255/35R18. This is obviously a quick fix to just get us home. We are getting an FTM fault and a transmission fault. I'm assuming this is just due to size difference and wheel speed? Will be fixing this after our drive home just want to ensure we won't damage anything else.

You might break your differential with that kind of tire size difference's.

Both those sizes are very wrong, sure you didn’t typo?
