Tyre pressure warning...

Just wanted to comment on how clever the tyre pressure warning system is on the GTI.

I was driving into work last week and the warning light came on on my dash. Unfortunately I didn't have the means to accurately measure my tyre pressures so I put some air in each and reset the system to get me home.

The next day, I reset all the tyres to 2.4 and reset the system again.

A week later I'm thinking maybe it had been a system fault but, no, this morning the warning came up again. Now armed with a pressure gauge, I was able to detect that the right rear had fallen from 2.4 to 2.0 during the week.

Clearly I have a very slow puncture or a dodgy valve or something. I guess I'll need to get it checked out as I assume it will only get worse.

I was wondering what people's opinions are on getting tyres repaired - I've only done 8,000 miles and given it is a rear tyre it still looks almost new. If it does turn out to be a small puncture, is it a good idea / safe to have a repair done? I have 18" Continental Sport Contact 2 tyres.

All feedback welcome! Thanks in advance...

For my own peace of mind, i would always replace a faulty tyre, especially on a performance car.

I had a rear tyre blow out on me once, on the M11 doing over a ton.. was certainly an eye opener..

now i would rather just know that i had a healthy set of shoes on. 169144-ok.gif

I'd just like to add how stable the GTI is after an immediate tyre deflation.

We hit a pothole at 70mph on the M25 in the MKV GTI. The impact was severe enough to deform the 17" Monza and cause the front left tyre to deflate instantly. SWMBO was driving and didn't realise the tyre (Bridgestone Potenza) had gone down. To be fair the only reason I knew for sure is because I heard it go.

I guess if you lost a tyre completely it would be a different matter, nevertheless the car was extremely stable with a completely deflated front tyre.

I had a screw in the centre section of my rear tyre last month, first I knew was tyre pressure warning light. stopped at a garage and pumped up all four tyres, reset and continued journey, next day the warning came on again and the offending tyre had dropped down almost 10psi.

mobile tyre fitter came out and repaired the tyre rather than replace it (only had 3000 miles on it - at least half motorway miles)

haven't had any issues with it since.

As long as a Tyre Fitter believes its possible to do a safe repair, I would go with their Professional opinion. So far no tyre fitter I've been to has ever suggested doing a repair where it wasn't possible, or was even a risk. So far luckily its only been the once that it hasn't been possible - £20 max vs £100+ for a tyre, always a good thing when its a cost you aren't expecting.

I had a slow puncture on my rear left which was triggering the tyre sensor so when I headed for work one day and it came on I just assumed it was the same problem.

I managed to get to work, 25 miles, then noticed that it was actually the front left that was the problem and it was completely flat blush.gif In fact it was steaming.

The only time i noticed the lack of grip was heading onto a roundabout and I was getting a bit of understeer. Says alot for the Conti's and the car that is was still driving so well.

Needless to say the tyre was fecked and the next time the orange light comes on I will stop.

I've had a blow out before and your right about one thing it really is an eye opener to say the least. I have had slow punctures too and most tyre centres would repair these if it were deemed safe to do so, they would not repair one that was close to the side/tyre wall etc. and if grip/grooves were ow. But I do agree with other posts, its better to know that you have a solid set of shoes under you as the tyre is the only thing that seperates you from the tarmac and a good set of boots could make the biggest difference.

Oh well!!! Someone upstairs seems to have been listening to my posts, and decided to inflict me with a puncture :S, A nail toward the inside edge of tyre - essentially from what I can tell looks like it'll need a replacement. Seeing as the set are the original set and have managed 20K miles, I think I'm looking at a new set. ...at the same time as my insurance... lol

Luckily Chester where I live and work has seen fit to set up an 8 week set of roadworks near where I work, which is causing all manner of fun, so I've been cycling in, plus next week I'm on Hols, so hopefully I can put it off till I return (just as long as it looks like the tyre will hold its pressure until then - not keen on wasting the spare on this instance.

Give etyres.co.uk a try. I just had my other 3 tyres replaced today by them so I now have a full set of Goodyear GSD3s.

Kwik Fit charged me £172 for the privilege of letting them scratch my alloy while fitting one last week after a puncture.

The etyres guy came to my office today and did the other 3 without putting a mark on them, all for £116.90 per tyre! Highly recommended.

Don't know if they have any mobile fitters but a really good place i've found to buy tyres is blackcircles.com but if anyone's going to buy from there pm me first and i'll send you a link then I get £5 put into my account from them!! Yeh! 169144-ok.gif

i've used mobile tyre fitters for about 4 years with no problems at all. not a mark on my 18" Monzas either.

for the record the total cost of the repair on my tyre was £23.50 inc VAT, which isn't bad, and if the tyre had not been repairable they would have come back and fitted a new tyre without charging for the first visit. all very reasonable!

I took mine into Denmead Tyre Services on Saturday. I had a nail in my rear driver's side tyre causing a slow puncture.

I enquired as to whether they were confident they could work on my Monza II's without damage. They assured me I had come to the right place.

Anyhow, they repaired the tyre for £13.95 without putting even a hint of a mark on my wheel. They said it was safe to repair and would not have done so had there been the slightest doubt.

So a big thumbs up ( 169144-ok.gif) for Denmead Tyre Services. I would definitely recommend them to anyone in the Portsmouth / Waterlooville area. I have been impressed with them in the past and their prices seem pretty good.

4 days after getting 1 puncture repaired, my warning light went off again yesterday. I had a nail in the other rear tyre this time! Thankfully, I was able to get that repaired as well. I reckon the Tyre Pressure Warning Sensor could have saved me having to buy 1, maybe 2, new tyres. Without the warning, it would be quite easy I reckon to damage a rear tyre by driving it while too flat... given they are so low profile I'm not sure you would notice until it was too late.

Warning went off this morning on the way to work. Stopped at garage and after topping up 3 tyres, 2 of which were actually OK but the 3rd was down to 25psi, then found that the drivers side front was very low, and wouldn't take any air. Presumably there is something wrong with the valve; either way I didn't fancy putting space saver on as I travel home on M1/M25, so called etyres and someone coming out to fit them this afternoon. £129/tyre all in for Potenza RE040, 18s

Very impressed with the service over the phone, so hopefully will be the same when they come out. Will let you know...

They are bringing 4 tyres as I've now done 27.5k on the first set and had been putting off replacing them (27.5k - is that a record!? Right foot is fairly light, if not in general then I try not to spin the wheels from standing start). May as well bite the bullet and do all 4 even though the rears look OK. Guy on the phone said it's probably best to do all 4, which I assume makes sense from performance perspective

Went for Potenzas if only because that's what I've got now, although I have heard good reports on other tyres from this forum

As per other posts the tyre seemed pretty stable despite being way down: I think the Potenzas have a stiff sidewall so maybe that's why

Very impressed with the tyre pressure warning, which could quite literally be a lifesaver. Am driving London-Leeds and back at the weekend so good that it's happened now and not at high speed

I have done 7k on mine and have already had to put the fronts on the rear to get more life out of them (dunlops).

However after doing it my sensor has come on. I am a bit worried about this, not checked out the PSI yet, but does anyone know that the rear or front tyres would have more PSI on factory delivery as I have not checked them since purchasing the car!

Help!

I switched the wheels themselves not the tyres, so should I still keep it pressed?

I will go and check the PSIs, if they are ok, I will press it? - that the best course of action?

First check the tyres, and adjust if necessary to the correct pressure. Then press the button until you hear the "bong". You've now "told" the sensors what the correct pressure is for each tyre. The warning light will only come on if a particular tyre gains or loses pressure after that.
