Most punctures in the tread area of a modern radial tire can be satisfactorily repaired today with what can be described as a combination "patch n plug". A careful tire tech will not enlarge the puncture significantly as the plug portion is fed into the hole with an injection tool - NOT like the plugs of old where a small nail hole was reamed out to about 1/4 inch. A careful tech will also use proper care and good equipment and avoid damaging the wheel in doing the repair.
Finally, even a proper repair reduces the speed rating of the tire but should not invalidate any tread-wear or manufacturer defect warranty.
Good luck and keep away from construction sites -- the best way to avoid flats!!
: I've got some experience with tyre patches since I managed to put a 4" nail into one of my 2 day old Dunlop SP9000's 3 months ago (Wasn't the Z3 but my Prelude VTEC). This was repaired at a tyre garage using a patch with a plug sticking out of the centre. The patch was glued to the inside of the tyre with the plug pushed out thru the puncture and cut level with the tread.
: I've since done two 700 mile trips running on the motorway at 100-120 MPH on average. I think after that, it's safe to say the patch works well enough! :) This method works only on tread punctures, not those on the sidewall.
: Personally, I wouldn't trust a plug (with no patch) simply pushed into the hole. Having said that, I believe many people have used simple plugs with no problems.
: Z3 2.8 / Prelude VTEC
: : Yup-
: : Unfortunately I looked out my office window this afternoon and noticed that the passenger-side rear tire was about half its normal profile. Drove gingerly to the nearest tire shop and they proceeded to extract a 1.5" finishing nail out of the tire. (Nicking the rim in the process *&^%$^%#)
: : Obviously the only other thing I could do is to lay out the cash for a brand new Pilot, but what I'm wondering is,has anyone had a bad experience with a patch? I was told it's guaranteed for the life of the tire, and the tire only has 9K miles on it...
