TRUCK & TRAILER TELEMETRY + REALISTIC TIRE WEAR 0.9.6.2

TRUCK & TRAILER TELEMETRY + REALISTIC TIRE WEAR
Your tires now wear out. Every tire on every vehicle, from a light car to a semi pulling a road train, has its own condition from 100% down to 0%. When a tire reaches 0%, it actually goes flat.

------------------------------------------------------------
HOW THE TIRE WEAR WORKS
------------------------------------------------------------
Wear builds up from four things, the same ones that wear out real tires:

- Distance: every kilometer you drive wears the tread a little.
- Load: each tire's load is compared to its own normal load. Tires that get overloaded, like the outside tires in a hard corner, wear faster.
- Sliding: wheelspin, locked brakes, drifting and scrubbing through corners take off the most rubber.
- Heat: above 110 °C, sliding does more damage, up to 3x when a tire is very hot.

Wet roads, mud, snow and ice wear tires more slowly. Wear stops while the vehicle is parked. Resetting the vehicle gives you fresh tires.
OVERWEIGHT PENALTY (US FEDERAL LIMITS)
Truck and trailer tires wear faster when an axle is over the US federal interstate limits:
- Single axle: 20,000 lb
- Tandem axle: 34,000 lb
- Gross vehicle weight: 80,000 lb

The mod works out on its own whether each axle is a single or part of a tandem. Empty or lightly loaded trucks get no penalty, legally loaded trucks wear normally, and overweight trucks wear faster the more overweight they are. Cars stay far below these limits, so they never get the penalty.

TESTED TIRE LIFE (approximate)
- Race car, hard laps on a circuit: about 30 minutes for the most-worked tire
- Semi, legally loaded, normal driving: about 2 hours
- Semi about 20% overweight: about 1.5 hours
- Empty truck: about 2.5 hours
Tires that work harder wear first: the outside front tire on a circuit, and hot drive tires on an overloaded semi.
WARNINGS
- LOW: below 20% condition, the tire is getting close to failing
- FLAT: at 0% the tire deflates for real

TIRE WEAR
Tire condition for the vehicle you're driving, car or truck. One row per axle, left tires on the left and right tires on the right. Each tire shows its % with one decimal, colored green to red as it wears.

TRAILER TIRE WEAR
The same layout for every trailer you're towing, grouped as Trailer 1, Trailer 2 and so on. Works with road trains, not just the first trailer.
TRAILER TELEMETRY
- Truck weight, the gross weight of each trailer, the total for all trailers, and the gross weight of the whole combination
- Every axle of every trailer in the chain, with axle load in kg and left/right balance
- Brake and tire temperatures on every trailer wheel

VEHICLE TELEMETRY
Brake and tire temperatures and axle weight distribution for your own vehicle, car or truck.

------------------------------------------------------------
NOTES
------------------------------------------------------------
- Works with standard BeamNG vehicles and trailers, including dual wheels. Each dual set counts as one tire.
- Weight readings come from the real mass of each vehicle, including cargo.
- Install: put the zip in Documents\BeamNG.drive\mods\ and restart the game. Don't keep older versions of this mod installed at the same time.

FOR TUNERS
The wear rates are at the top of lua/vehicle/extensions/auto/tireWearEstimator.lua:
- K_ROLL: rolling wear, sets truck tire life (double it to halve tire life)
- K_SLIP: sliding wear, sets circuit tire life
- WF_OVER_SLOPE / WF_MAX: how hard overweight axles are punished

CHANGELOG — v0.8 → v0.9.6
v0.9.6
- Added console test commands for tuners:
setCondition(pct [, wheel]) sets tire condition
forceLeak([wheel]) starts a leak right away
v0.9.1
- Fixed PSI always reading 0 (it now shows real gauge pressure,
about 93-97 PSI on the stock semi)
v0.9.0
- New: slow random leak. At 10% condition or below, a tire has a
50% chance to start leaking, then again every 5 minutes. A leak
drops pressure to a random 40-60% of normal over 1-5 minutes
- New: grip loss on worn tires, in 5% steps: 100% grip down to 25%
condition, then 95 / 90 / 85 / 80 / 75%, and 70% grip at 0%
- New: tires cool faster when stopped on wet surfaces or mud (3x),
snow or ice (4x), and water (6x)
- At 0% the tire still goes fully flat; a vehicle reset (Ctrl+R)
restores grip, pressure and wear.
