I know all about tires, and that’s a very broad and often wrong generalization. An MB C-class wears 225/45R18’s up front, narrower than your average Camry, and A-class comes with 205/55R17’s, which is practically a bicycle tire. And no, you don’t need to buy overpriced tires from MB, so bragging about a Benz doesn’t necessarily imply your tires are expensive. Tire rack will do just fine, which is how I put 255/35(Z)R19’s on my ride. Without specifying the model, or even AMG, it sounds more like a weak boast than someone making a knowledgeable point about tires and how much they cost.
Look, you were the one who asked the question, using strong language whose subtext was to suggest that such a relationship was ridiculous:
What on earth does your car brand have to do with the price of the tires you put on?
I responded with reasonable language saying it's not ridiculous -- there can be a relationship:
Higher-end cars tend to have larger, wider wheels --> larger, wider, lower-profile tires --> more expensive.
Note my deliberate and careful use of the word "
tend",
which explictly means that this is a broad generalization.
Indeed, my mild statement is really no different from saying that more expensive cars tend to have more expensive components, and larger tires do tend to be more expensive.
So now, in response, you're complaining that what I presented as a generalization is -- what -- a generalization??
Of course you can always find exceptions. For instance, you can find exceptions to my statement that larger tires tend to be more expensive -- I'm sure you can find a small tire of a particular model that is more expensive than a larger tire of a different model. Does that invalidate the generalization? No, that's the nature of generalizations.
This could be tested rigorously by actually getting the tire sizes for every model of every passenger vehicle, plotting them against vehicle price, and seeing if there is a relationship that is statistically significant.
But I don't think even that would satisfy you -- I'm thinking you were just in the mood to start a fight.
Plus your MB C-Class vs. Toyota Camry comparison was dishonest, since the former has staggered tire sizes, and you deliberately omitted mentioning the rear tires on the C-class, which are larger and lower-profile. The 2020 Camry has four tire sizes. I'd put the LE as the average, especially weighted based on sales. Comparing buying tires for the 2020 Camry LE vs. the MB C300, the C300 is more expensive. Not a lot more, but using Tire Rack prices for a Pure Contact LS (chosen because it's available in sizes for both cars, and is a solid middle-of-the-road brand) it's $590 for the Camry LE and and $680 for the C300. Going to the higher end in both Toyota and Mercedes will inflate the differences.
Finally, the appearance of larger wheels in mid-market cars is a newer phenonmenon. For those that are replacing tires on older cars, the difference in tire size between Mercedes and Toyota is more striking than it is for the new ones.
