Vehicle weight and max towing capacity

[jmanwich]

Regarding the bullet point:
better tire forces (example : no more possible to pull more than your weight)

I would like to suggest that this be increased to a more realistic 300% - 400% of the weight of the vehicle. The reason I'm suggesting this is a 2025 Kenworth W900 between 17,000 and 22,000 pounds while a 2025 Peterbilt 589 typically ranges from 12,000 to 22,800 lbs yet both of these vehicles routinely pull a total load of 40,000 pounds of product plus the weight of the vehicle and the weight of the trailer for a total of 80,000 pounds down the highway here in the U.S.. Although, oversize loads are quite frequently hauled weighing far more than this.

This is not limited to just Semi-Trucks as I have personal experience towing 10,000 pound delivery vehicles out of snow drifts and muddy ditches with a Chevy Silverado 1500 LS that did not have four wheel drive and weighed only 5,000 pounds.

Overall, I like the direction you are going with this mod but I would recommend if you are going to premise the mod being based on making the game more realistic than the changes you are making should be more in-line with real world examples.

Have you played with this mod yet to make such a claim? I'm asking because currently, you can easily pull a trailer full of wheat (6700 liters), which gives a total weight of wheat + trailer = 7200 kg, with a tractor that weighs 1100 kg. This tractor only has drive on two small BKT 9.5-24 rear wheels, with a downforce of 320 kg on each of these wheels, So, this means the tractor currently has 655% greater pulling capacity than its own weight in this specific example. and it can pull this trailer in a field, even up a slight incline. So, in my opinion, the pulling power is currently too good, not too weak.

@jmanwich : Hi, when we talk of "weight" and "pull", the unit is Kn (kilo-newton)
in your case, you are talking of "masses" (kilos, ton, pounds)

what I meant is :
if your Kenworth, with a trailer fully loaded, is weighing 20T on the drive axles, it should not be able to deliver a pull greater than 20*9.81=196.2Kn on asphalt (ok, a little bit more than that because "hot" tire/asphalt contact can give better than 1 ratio)
with such a pull, it would be able to move far more than 100T on a flat road (provided the engine and transmission are suited to "take off" the load)

don't worry, I have sufficient example IRL on my side (sugarbeet harvesting for example or carting harvest grain => with farming tractors and trailers, in france)
and we can also check this by looking at "nebraska test lab" reports.
This is "physics" (torque, power, forces, rolling resistance)

Thank you for clarifying. When I read the description it came across to me as being related to the mass and I'm glad I was wrong.

I can't blame you : in France, we also mismatch the 2 terms everytime (we commonly use the "weight" term to talk about mass)
So, I guess this is the same everywhere.
And then, I didn't write a great descripton. I should have written : "no more possible to deliver more pull than your weight"
