TIRE PRESSURE C205 C43 AMG COUPE 2018

I was just wandering what is the ideal tire pressure for a 2018 coupe? Its Summer in Australia and I just drive mainly by myself or a passenger and she is light lol. like 50kgs.

I found some info below about it but was curious what others have. Didnt even know there was a difference between Summer and winter, mind you in Australia our weather is not extreme. ie snow.

I did search other threads, but couldnt find a proper title which I think is half the problem with a lot of these thread titles in terms of searching for information.


----------------------------------------------

2018 Mercedes-Benz C-Class Tire Pressure Levels

First, let’s take a look at the tires on the 2018 Mercedes-Benz C-Class modelsThe wheels and tires included on the baseline model of the 2018 Mercedes-Benz C-Class sedan are measured and cataloged as 17″ split 5-spoke wheels with 225/50R17 all-season tires.The wheels and tires included on the baseline models of the 2018 Mercedes-Benz C-Class Cabriolet and Coupe are 18″ twin 5-spoke wheels with 225/45R18 all-season front tires and 225/40R18 all-season rear tires.
  • 225/50R17 tires for the 2018 Mercedes-Benz C-Class sedan have an ideal pressure range of 32-40 psi (pounds per square inch).
  • 225/45R18 front tires for the 2018 Mercedes-Benz C-Class Cabriolet and Coupe have an ideal pressure range of 33-39 psi.
  • 225/40R18 rear tires for the 2018 Mercedes-Benz C-Class Cabriolet and Coupe have an ideal pressure range of 32-41 psi.

However, remember, pressure range can fluctuate. The lower range of pressure is better for colder temperatures, and the higher range of pressure is better for warmer temperatures. Additionally, more weight from cargo and passengers in your vehicle means your tires will perform better with higher tire pressure. Therefore, if you typically drive by yourself, chose a psi from the lower range. Meanwhile, if you typically have passengers and cargo, chose a psi on the higher end.

78 views and no one seems to be putting air into their tires at all.

Anyways I spoke to the dealership and they recommended 38 PSI for all 4 tires for anyone that is curious.

78 views... Hahaha! If you have stock tires, I would just follow what’s on the fuel cap cover. If you’ve already switched to non-rft’s like I have, I’m at 38f and 36r psi. I’ve found that to work best for me, with my driving style and ride comfort tolerance. I’m in southern CA, so we don’t get snow either.

Never ever had snow or driven in snow.

Wow, just wow. It must be such a different driving experience. I know this is where a car like the C43 is well ahead of the C63s in these conditions.

Curiosity question here: What brand/size of non-flt tires are you using and what do you do in the case of a flat tire?
