Assalamualikum Brother. Honestly brother i mean you no offence but would like to add some of my advise into your kind words to the owners of the Grande. BUt firstly since i do not own the car variant, i mean no one any offence when i say this :
Tyre pressure per Manufacturer is 30psi so anything over 32psi is not advised at all.
Wheel Alignment and Balancing are to be done pronto, asap on day 1 and can cause serious damage to not only the tyre, rims but instability issues that can and may cause an accident.
Drive carefully to avoid bumps. And keep a cool temper and foot.
Properly maintain your car.
Use any synthetic or semi-synthetic engine oil that does not go below 10W-30 or 10W-40 (max 4k to 5k km change interval on semisynthetic and 8k to 10k for synthetic. 5000km max, is my advise for any oil) with and good Filter. (5 km was a typo from our brother's end so i assume everyone understands)
Use any tyre you like but ECO Tyres may give better Economy but that is for the tyre gurus to explain.
Then enjoy the fuel economy of your car, and stay blessed and safe. Ameen. Jazakallah and Peace Out.
Apologize in advance if any one is offended here.
