Senior - BHPian ![]() | ![]() They're great tyres. Double edged sword, the infamous soft sidewall that bleeds at kerbs, but in this case helps the cause by dramatically improving ride quality when used with caution. Coming from RFTs, they were a delight, both in the city and on the highway. Of course, they are no comparison to performance sport tyres like PS3/4, P Zero or ContiSC5; but they are the optimum balance between comfort and performance for a layman. |

| ![]() Experts, I need a little advice regarding my RFT in F30. My Right Rear tyre went into a pothole causing a sidewall chip. The service advisor said that I should not worry about it as the cut was not very severe. I do a lot of highway runs so I decided to change the tyre. My car has done 23k so far. I have two questions - 1 - Is it okay to change just one tyre or should I change both rears? 2 - Service Advisor asked me to maintain 35 psi in all tyres. Is it a good advice? Tyres are Bridgestone Potenza 215/50/R17 RFT. |

![]() Hope you know a 35 psi can go upto 40 psi after an hour of highway run. I have checked it myself in my drives. Thats one reason people usually release little bit of air mid trips or start the journey with 3 or 4 psi less. About changing the rear tire, its good to check the tread depth and decide if you need to do one or both. Uniformity is linked to safety. | |

| ![]() I finally bit the bullet and bought Michelin primacy 3 ST for the 320d. The stock RFTs had done 42k kms and were now up for change. Most people on the forum seem to prefer the tubeless route and highly recommend it. But I am not really liking it. I have driven around 200 kms as of now while maintaining 33 PSI. Positives: The ride has completely transformed. It has come very close to what my Altis offers. Soft, cushioned and the bumps are not felt much inside the cabin. Negatives: As a price for the above, he driving dynamics have been spoilt. The car no longer feels like a bimmer as it used to be. I am disconnected with the road. The steering is not so sure anymore. Even the pick up feels sluggish. It is as if the engine is revving and wants the car to lunge forward but the tyres are holding it back. High speed stability is something that I look forward to test during this weekend but within city limits it was just average. Moral of the story: I am not so sure if the improvement in ride quality is worth trading the car's DNA for. The F30 didn't have a horrible ride quality to begin with. I wish I had stayed with the RFTs. I am going to try increasing the tyre pressure gradually to see if I find a sweet spot where it behaves a bit closer to the RFT set up. Advice: For F30s do try to get hold of a BMW on tubeless before switching. You may not like it that much. |

There is always some chauffeur driven BMW owner wishing for a better ride.... sell your tyres to him at maybe a small discount over what you paid.... And then go back to RFTs. The sooner you do this, the better. Spread the word asap among your fellow doctors and BMW owners. | |

| ![]() I am not looking to change now. Will use them a bit longer to see how they behave. Wife is liking the added comfort and hence there is no going back now. BTW just to make everyone aware here, the following was BMW's reply regarding warranty status if you opt for switching to tubeless. Quote:

In your case you are not enjoying the tubeless for 2 reasons - 1) Your car has 16" rims with a higher sidewall by default. In RFTs the sidewall is stiff, but now you have switched to tubeless with a thinner sidewall. And with the higher profile tyres in your car it will be even more noticeable. 2) You chose comfort oriented tyres. Possible that more sporty options were not available in your size. But Primacy 3 ST is a comfort oriented tyre, so this along with the higher profile tyres are bound to take away from the fun. If your car had 17s, and you had the option of taking a sportier tyre (Michelin PS4, Yoko Advan Sport) the handling and grip would have improved and you would have gotten a better ride. Primacy 3 ST works on vehicles like the early F10 5 series which had a stiff suspension by default, on the F30 it was very bouncy in the initial days. So I would say your case is the exception, rather than the norm. As for the warranty, yes that is the official word - But many people I know including myself, have had warranty claims while running tubeless tyres, some even suspension related. But if you are going to ask BMW of course they will say any change from OE Spec will void warranty. | |

| ![]() Hi Members, I have year old BMW 320d (11000Kms done) with current setup of Goodyear 225/45/R18 91Y. I am facing huge issues with tyre bulge and have already got 4 tyres replaced. I am in gurgaon and road conditions are terrible. Now from whatever study I have done, the issue boils down to side profile of the tires. What should I do, try and downsize to 17inch alloys and RFTs with better side profile or change to tubeless with existing profile? I am ok with ride quality, just don't want these bulges and tire damage needing replacement. Also how does the insurance with tyre secure playout incase of after market fittment. Right now BMW manages the replacement and insurance. I have TATA Aig insurance with tyre secure. Thanks, Rohan |

| ![]() Hi Guys So I need to change the tyres on my BMW 3 series.. I currently have Bridgestone Potenza 225/50R17 94W Company installed. They are charging me a bomb for replacements and I am looking for the tyres from a vendor outside of BMW. I have a silly question. I have found Bridgestone Potenza S001 225/50R17 98Y - 98Y being the difference. Does this make a difference in terms of performance rating or is it just batch number of sorts?? Can I go ahead with the 98Y?? |

| ![]() 98 is load rating, higher the better. Y is speed rating. Y means 300kmph, certainly better than W. So just go for it man. BTW, I also bought the 330i recently and closely watching all such threads to smartly manage the ownership costs. Dealers loot, I see. Can you share the price the dealer is quoting and the price you are getting from outside? |

I am getting them from the Bridgestone website. Which is great come to think of it. Haven't really checked any retail store as I feel online costs would be cheaper than a brick and mortar store. Thanks again | |
