Run-Flats ? Repair or Change

[Darien T]

Hi guys,

Had my first flat tire on the run flats last week.

The warning came on the idrive and i drove on for quite a bit as the ride was not compromised in any way.

Called the service people who advised me to pump air back into the tire to find out if it might be a false alarm.

All was well but the next day, the warning indicator came on again, confirming that it is a real puncture.

Following that I simply paid a couple of bucks and patched it up the usual way at one of them tire shops.

Alls well again.

Theoretically, it really should not affect the run flats and the run flat system.

In fact, I was pretty happy with the run flats as my night / day was not ruined just cos of a simple puncture! I could drive on and not worry about my tires will I patch them up at a more convenient time.

Of course, we shouldn't drive on forever but it was brilliant actually!

My run flats needs a serious pump every like 2 weeks, esp the one at the driver's seat. Wonder if its a tyre problem or its normal. Another problem is traction, find run flats have really lousy traction.

Isit better to drive on run flats or better normal tyres? Like CSC3. Bros pls hlep
Thkx!

pumping once every 2 weeks seems normal to me... I'm running staggered so i pump once a week to make them last longer/wear out more evenly. When they puncture, you'll get the tire flat warning within a week at most... more likely 2 days.
I've had 5 punctures on my run flats the last year... tried all 3 methods as mentioned earlier in this thread to patch them at various times... In the end, it was a huge mofo nail near the inner sidewall which rendered the rear 255/35 tire irreparable (internal patch only lasted for 3 weeks)... got it replaced for $520.
I was originally going to change to non-RFT after the entire set wore out, but i think the benefits of RFT technology outweighs the cons (stiff ride/avg grip etc.) so I'll probably stick with RFTs.

punctured on sidewall or near sidewall is not recommended to repair in the first placed
so what you did to replace new tyre is right and best solution.in term of maximun safety.

Here's some "official" notes from the Bridgestone website on RFT repairs, and the range of tires they supply for bimmers. Apparently repair is possible up to certain limits for RFTs supplied by Bridgestone ... read on pls ...

RFT need not be as expensive as $500 or more per piece...just need to enquire around . From what I understand, currently there's 2 brands available in S'pore - Bridgestone and Goodyear.

For my E60 (17", 225/50), I had it for $330 (w/GST) per piece (Goodyear). It was changed due to regular wear and tear. However if you just have a puncture, please have it checked at a regular tyre shop.

If the puncture occurs along the grooves / thread of the tyre, no sweat. It can be easily/safely patched for a mere $8 - $10 per hole. If the puncture occurs on the sidewall (ie. inner or outer), then in the interest of safety, the tyre (regardless of new or worn) has to be changed.

RFT are definitely more expensive than your typical tyres. Tyres are what separates you from the road. Get a good quality one.

So, RFT or regular tyres? The choice is really yours.

you are right safty is above everything,did you regular shop doing the proper repair internal patching which allow them to carry out the thorough internal inspection? is no point that the leak is stopped but tyre had a internal injuries or demaged which is still consider dangerous to use them.

I am no expert in tyres, so I leave it to the professionals. If the guy says it's safe to just plug it rather than to change the whole tyre, who am I to say he's wrong ?

Of course there are obviously others who will not hesitate to scare monger you into changing all 4 pieces too.

So, a regular tyre shop located in a shop house by the roads, bigger outfits (eg. Autobacs, Stanford Tyres), or back to PML ??

The choice is really up to you. Do your own homework (if possible) before deciding. That way, it'll save you a heartache subsequently.

Cheers!

if you read the tyre side wall(very small) that stated no repaired is allow,but i think if the punctured tyre if is not drivened for too long distance and get the proper repair procedure by seperating the tyre and rim get internal checking for any hidden injuries or demaged and patch up(plaster) you should still safe to use the repaired tyre,those tyre shop wether big or small carrying out a external insert is considered not the appropiate way of repair.
