Nail in RFT

Went out to pick up a friend for dinner, and just as I took the car out from the parking, heard a flapping noise. Got off and saw a 1 inch nail sticking out of the rear left tire. Pulled it out ( it was only in by about 1.5 cm or less), and drove for around 14 mikes when all of a sudden the steering started getting unexpected feedback. This happened for a stretch of 3 miles, and the road seemed a lot uneven there. Then again everything got normal. Returning back, same thing happened on a similar stretch...and then for next 14 miles everything appeared fine. Also, there were no warnings on the dash.

I am just concerned if this is a known Z4 issue ( have driven it for almost more than 300 miles, though never been on the mentioned stretch, and nothing similar ever happened before), or related to the stuck nail.

My Z4 is a 2003 model ( I am the second owner, been only 2 months), and in almost perfect condition. Tires are also new.
 
Did any tyre pressure warning lights start flashing at you? Sounds like a very bad case of tramlining, maybe exacerbated by low pressure on that tire. You should have gotten an alarm if that was the case though.

Either way, get that tire damage seen to as soon as you can.
 
Hi and welcome to the Forum :thumbsup:

Think I might have checked the tyre pressue as soon as I pulled the nail out - for my own safety as well as everyone else's. TPM is an indication of a pressure variation in one tyre causing a change in overall circumference which gives an indication of low pressure only and which could be caused by a puncture. As MrPT get it checked quickly!
 
Hi not sure now thick the outer wall of a rft is, but I'm wondering whether the nail would have been better left I'm, driven slowly, then to a tyre place who can do repairs. Obviously depends on how much nail was sticking outside of the tyre, and where the damage was. However I'm thinking could have kept it in for trying to salvage the tyre if minor damage.

I so remember the flapping noise!! I had that when I drove over an L shaped rod that some idiot had dumped in the road, large enough to render my rear rft useless. Though it got me home safely. I didn't see it in the road and despise people who dump s**t in the road. This is dangerous for drivers and motorcycle riders :driving:
 
Thanks Alan, Okandacorns, MrPT.

It was late night, so couldn't get any Service Centers to have a look. There were no indicators for tire damage or any warning lights, so took the car to work today, and didn't feel a thing. Went through the entire owners manual last night. Isn't the dash supposed to bring up the pressure warning lamp if there was a puncture?


Will get some mechanic have a look today.

Check your pressure asap. The warning light doesn't show up if its a slow puncture. I know this from experience of runflats on my old z4. I drove on a rear runflat for quite a while with no pressure, only thing I noticed was TC cutting in more than usual
 
Was about to say the same thing as Dogmatic6, as far as I know the sensor is only capable of triggering if it registers a sudden drop in pressure.
 
Ah, that's interesting - will definitely be checking my pressures more frequently if that's the case.

I guess there must be some day-to-day variation in pressure/rolling diameter, and if the system normalises itself to take account of this I can see how it's possible that it won't detect a slow puncture.
