> **Use Up Your Tyres + UsedPlus = Realistic tire economics**

## Overview

UYT (Use Up Your Tyres) integration synchronizes tire wear, making [[Vehicle-DNA|DNA]] and condition affect tire lifespan.

---

## How It Works

| System | Responsibility |
|--------|---------------|
| **UYT** | Tracks tire wear (surface, speed, load) |
| **UsedPlus** | Reads UYT wear %, calculates flat chance |

---

## DNA Integration

Vehicle DNA modifies UYT tire wear rates:

| DNA Profile | UYT Wear Multiplier | Tire Lifespan |
|-------------|---------------------|---------------|
| Legendary | 0.5x (half speed) | 200% lifespan |
| Workhorse | 0.6x | 167% lifespan |
| Average | 1.0x | 100% lifespan |
| Lemon | 1.4x | 71% lifespan |

Lemons burn through tires 3x faster than legendaries.

## Flat Tire Probability

| UYT Tire Condition | Flat Chance (per 100 hrs) |
|--------------------|----------------------------|
| 90-100% (New) | 0.1% (rare) |
| 70-89% (Good) | 0.5% (occasional) |
| 50-69% (Fair) | 2% (moderate) |
| 30-49% (Worn) | 5% (frequent) |
| Below 30% (Critical) | 12% (very frequent) |

Strategy: Replace at 40-50% to avoid breakdowns.

## Quality Interaction

UsedPlus quality tiers affect UYT wear:

| Quality | UYT Wear Multiplier |
|---------|---------------------|
| Excellent | 0.67x |
| Good | 0.85x |
| Fair | 1.0x |
| Poor | 1.25x |

**Lemon + Retread** tires:
- DNA: 1.4x
- Quality (Poor): 1.25x
- Total: 1.75x wear
- 500-hour tire dies in 285 hours

**Legendary + Premium** tires:
- DNA: 0.5x
- Quality (Excellent): 0.67x
- Total: 0.335x wear
- 500-hour tire lasts 1493 hours

## OBD Scanner Tire Service

With integration, [[OBD-Scanner]] adds tire service:

| Repair | Cost | Result |
|--------|------|--------|
| Patch | $100 | 30% condition |
| Plug | $200 | 50% condition |
| Retread | $500 | 65% condition |

Not replacements - just enough to finish work.

## Economic Impact

**Lemon Tractor** (500 hrs/year):
- DNA: 1.4x wear
- Tire life: 357 hours
- Cost: $2,800/year

**Workhorse Tractor**:
- DNA: 0.6x wear
- Tire life: 835 hours
- Cost: $1,200/year

Lemon costs $1,600 more/year in tires alone.
