Tire Index Parser

A Dart and Flutter package for parsing and validating DOT codes, Load Indices, and Speed Indices for tires. This package helps extract information like manufacturer details, load capacity, and maximum speed from tire specifications.

Features

• DOT Code Parsing:

  • Extract manufacturer details from DOT codes.
  • Validate production date (week and year) in DOT codes.

• Load Index:

  • Validate load index values.
  • Convert load capacity to lbs or kg.

• Speed Index:

  • Validate speed index values.
  • Get maximum speed in km/h or mph.

Getting started

Prerequisites

• Dart SDK >=2.18.0 <4.0.0
• Flutter SDK (if used in a Flutter application).

Installation

Add this package to your pubspec.yaml:

dependencies: tire_index_parser: ^1.0.0

Usage

DOT Code Parsing

import 'package:tire_index_parser/tire_index_parser.dart';

void main() { String dotCode = "DOT 1VR 100WNM 3724"; var tireInfo = DotParser.parse(dotCode);

if (tireInfo != null) { print("Plant Code: ${tireInfo.plantCode}"); print("Week: ${tireInfo.weekCode}"); print("Year: ${tireInfo.yearCode}"); print("Manufacturer: ${tireInfo.company?.manufacturer ?? "Unknown"}"); } else { print("Invalid DOT Code"); } }

Output: Plant Code: 1VR Week: 37 Year: 2024 Manufacturer: Bridgestone

Load Index

int loadIndex = 50; int lbs = IndexService.parseLoadIndexLbs(loadIndex); int kg = IndexService.lbsToKg(lbs);

print("Load Index $loadIndex: $lbs lbs (${kg} kg)");

Output: Load Index 50: 419 lbs (190 kg)

Speed Index

String speedIndex = "H"; int kmh = IndexService.getSpeedInKmH(speedIndex); int mph = IndexService.kmhToMph(kmh);

print("Speed Index $speedIndex: $kmh km/h (${mph} mph)");

Output: Speed Index H: 210 km/h (130 mph)
