I am considering buying the BMW M340i and have heard from a few sources, including a BMW service technician, that it may be prone to frequent tyre punctures or sidewall damage due to its low-profile run-flat tyres and minimal sidewall height. Could you please clarify whether this is a common issue in real-world Indian driving conditions, especially on highways and roads with occasional rough patches? Also, would switching to non-run-flat tyres or opting for a higher sidewall setup significantly reduce this problem?

On the BMW M340i, what you’ve heard is largely true in Indian conditions. The car comes with low-profile run-flat tyres that have stiff, reinforced sidewalls. This helps you continue driving after a puncture, but it also means there is very little cushioning. On rough roads or sharp potholes, the impact is transferred more directly to the tyre and wheel, increasing the chances of sidewall damage or bulges. This is not a constant issue, but it is something owners do experience on broken roads or bad patches, especially at speed.BMW M340i

Switching to non-run-flat tyres does help. They offer more sidewall flex, which improves ride comfort and reduces the likelihood of damage. Moving to a slightly higher sidewall setup will help, too, but to maintain the overall diameter, you would need to switch to smaller wheels, which adds to the cost.

Since the M340i already comes with a space saver spare, switching away from run-flats is much easier and more practical, as you still have a backup in case of a puncture.

It is also worth noting that this is not unique to the M340i. Cars like the Mercedes AMG C43, which are sportier versions of the standard model with larger wheels and lower-profile tyres, face a similar risk on poor roads.

Dear Autocar India Team, I am writing to highlight a serious ownership concern with premium Volkswagen Group CBU SUVs in India. I own a Volkswagen Tiguan R-Line costing over Rs. 60 lakhs on road. After tyre damage, I approached the authorised service network and was informed that the OEM tyre size - 255/45 R19 - is not available in India. This is a safety-critical consumable, not a cosmetic accessory. For a premium CBU SUV, it is deeply disappointing that owners are left struggling to source the standard tyre size after damage. This concern may not be limited to the Tiguan R-Line alone. The Volkswagen Tayron R-Line in India also uses the same 255/45 R19 tyre size, and the recently launched Skoda Kodiaq RS uses another rare performance tyre size, 235/45 R20. This raises a larger question: are premium CBU models being sold in India without adequate long-term tyre and consumable support? Insurance has approved an alternative tyre size in my case, but that does not solve the core issue. Owners should not be forced into non-OEM tyre sizes because the manufacturer has not ensured the availability of the factory-specified tyre. I had publicly raised this with Volkswagen India, but received no response. I request Autocar India to kindly look into this and raise the issue with Volkswagen India / Skoda Auto Volkswagen India, so that either OEM tyre availability is ensured or formal written guidance is provided for safe alternative tyre sizes. Regards, Dr. S. Alagu Ganesh Madurai

We’ll take this up with Skoda Auto Volkswagen India right away and ask for a clear tyre support policy, stocking timelines for 255/45 R19 and 235/45 R20 in India, and written guidance on approved alternates. We will publish their response. You’re right to call this out. A Rs. 60 lakh CBU that leaves owners hunting for a basic, safety‑critical size is not acceptable. No doubt, import curbs and BIS rules have choked niche sizes, but that is the OEM’s job to solve with their tyre partners, not the owner’s problem.While we push for a fix, two practical options keep you mobile without straying far from spec. For Tiguan R‑Line 255/45 R19, the closest matches are 245/45 R19 or 235/50 R19. For Kodiaq RS 235/45 R20, 255/40 R20 is closest. Only choose tyres with equal or higher load and speed rating, check full‑lock clearance, and do an alignment. With AWD, replace in pairs at a minimum, ideally all four, to avoid drivetrain stress. Expect a small speedometer error.

I have a Grand Vitara Strong Hybrid, and I am extremely satisfied with its mileage (900-1000 km from 45 liters). However, I am losing the joy of driving. I migrated to this car after owning a Swift Dzire Diesel and an XL6. The mismatch between engine revs and acceleration is becoming unpleasant. Overtaking feels riskier, and even the brakes feel spongy. I have experienced a few unpleasant situations because of this. As a result, I have reduced my overall speed, making the safety of my family a bigger priority. But the driver in me is unhappy. Should I upgrade to the Duster Hybrid, the Hycross Hybrid, or the newly launched Sierra EV? Also, do diesel engines still make sense today?

From what you've described, the Grand Vitara Strong Hybrid has impressed you with its efficiency but left you wanting more from behind the wheel. If driving enjoyment is back on your priority list, the Duster Hybrid looks like the most natural upgrade. It is expected to offer a much more engaging driving experience while retaining the fuel efficiency benefits of a strong hybrid.The Toyota Innova HyCross Hybrid will certainly improve on comfort, refinement and performance, but it won't fundamentally change the character you're looking for. It is still geared towards relaxed family motoring rather than enthusiastic driving.The Tata Sierra EV is an interesting option and has now been launched. It promises strong performance, a premium cabin and a spacious interior. However, if the "driver in you" misses the involvement and confidence of your earlier diesel cars, we'd still wait to experience how the Duster Hybrid drives before making a decision.As for diesels, we don't think they should be ruled out altogether. With the right usage, they continue to make sense. However, given your appreciation for the fuel economy of your Grand Vitara and the direction the market is heading, we'd lean towards a strong hybrid rather than going back to diesel.
