RFT Tires Bulge

[TheTinkerer]

Finally got my car back from service centre and sent it straight to tyre shop for replacement. It's the exact same tyre as stock with a much lower price compared to what AB Sg. Besi quoted me. Chatted with the owner for a while. He mentioned that there are lots of similar cases. If he was telling the truth, he has already changes 40+ pieces of such tyres in this month alone (which I think he refers to Dec/Jan).

Jalan Tun Razak

These prices quoted by SC are ridiculously high.
The one along LDP facing the curve wanted RM 2200, yet Jalan Tun Razak quoted RM 1700. PURE MADNESS.
splee is right, outside is cheaper to replace.

Bro,
Did your guy specifically point out which brand or RFTs in general?

Like this still not manufacturing defect ah? Then I don't know what is?

I replaced mine at 1180/pc.

Interesting.....has anyone developed this bulge on more than one tire at a time? Funny that similar complaints have not developed on those running Michelin or Bridgestone rubbers......:listen:

Is this a problem with goodyear rfts?

Based on this thread, it seemed that GY RFT is experiencing high possibility of the bulge issue.
Another point to note would be whether it is localised to certain dealership.
And whether it is restricted to vehicle model.

My ride is on Bridgestone RFT, Quill, F30 320d - 4 mths passed so far without problems (touch wood). Perhaps others can also specify the tyre brand, dealership and vehicle model to see if there is pattern developing.

Cheers

Are the tyres differ by dealership? I thought since its SKD, hence all should be the same. What I can say is GY RFT sucks. When I asked, the technician said not advisable to switch to other brand for only one tyre. If want to switch, better switch all since different model is of different thread design. So, if anyone has the opportunity to choose, my advice is don't go for GY RFT.

Just sent my car for inspection by the Goodyear tech. They took plenty of photos and examined all 4 wheels. However they will only tell me the result tomorrow. So its another day' wait as to whether I have to replace the tire myself.

They mentioned that the Goodyear Efficinet Grip RFTs are the next generation with more "forgiving" side walls. After driving for sometime, I must say it drives quite nicely. It also performed rather well on d recent weekend rempitz up to genting rest area.

Downside is that it is now more susceptible to bulges.

But improvement on ride comfort should not be at the expense of reliability. RFTs should be more reliable than conventional tyre as that's one of reasons it was created in the first place.

Report is in.... apparently its due to external impact. There is a small scratch mark and therefore not claimable under warranty. Moral of the story is that the Goodyear RFTs has been made softer so that its more comfortable at the expense of durability and reliability. I'll have to think about replacements now - back to Goodyear RFT, another brand's RFT or non-RFT (Michelin PSS? :burnout.

go for another brand bro, michelin is quiet reputable for its reliability

 

[patgwh]

Bridgestone is good too

guys make sure when changing your bulged tire to a new one....apart of the same size...make sure the speed rating represented by Y or W is also the same...ours factory fitted is 91Y..the tire dealer staff may overlooked this spec..so please be careful..price should be different and performance would be affected...

i think speed rating of Y and W doesnt really matter as our cars cannot hit more than 250km/h?

Hmm..looking at this it would appear that it is only GY that has this problem.

Mine is a 320d 17" came with Bridgestone, so far 6 months already, 12K on the road, had one flat tyre and drove it over 80km (had no choice, cud not pump air into it for some reason) even up to speeds of 140 kph (rushing to the airport), this was 3 mths ago and the tyre is fine.

Is it mainly 328s that came with 18" GYs? If all the bulges are only GYs, then it is obvious that it is a manufacturing problem.

true it is not the max speed limit that matter but the performance, durability and consistency with the rest of the tires as tire construction changes the higher the speed rating. Different components and different tread compounds are used in order to ensure that the tire can hold together at high speeds. This can and does have an impact in how your vehicle will drive at legal road speeds. i think thats why our factory tire rated as Y consider its big hp and torque...this is for people who really cares...

Hi bro, I asked around and people seem to advise if the rest of your tyres are GY RFT, you should stick to that unless you're willing to change all four. The same thing happened to me and I ended up changing to GY RFT with much hesitation. The reason given was that it could affect performance as the tyre thread is different if you only have one tyre of different brand/model. As other forumer said, remember to check on your tyre. I forgot to check mine and only found out that its a 91V instead of 91Y. The difference is the max supported speed.

91Y = 300km/h
91V = 240 km/h

Anyway, I'm still happy with it as I'm not gonna hit up to 240km/h.

 

[splee]

I am sure there is a reason behind why BMW is using 91Y as OEM tyre. In my opinion, best to stick with the same speed rating as the original.

i dont think its a manufacturing defect. it could be that BMW drivers are more aggressive? haha.

i dont have any issues with both 328i tyres. most likely driver's fault.
