Tyre Guides & Interactive Tools — NZ's Most Advanced Tyre Toolkit
From AI-powered tyre scanning to physics-based braking simulators, every tool is built in-house and 100% free. No sign-up required. Designed for New Zealand roads, vehicles, and WOF standards.
Physics-based simulators and real-time safety tools built for New Zealand conditions. Several of these are world-first tools we built in-house.
Braking Distance Simulator
19-factor UBPS physics engine calculates real stopping distances. Accounts for tyre type, road surface, gradient, weather, and vehicle weight. 95.4% accuracy across 974+ benchmarks.
Simulate BrakingBrake Reaction Time Test
Test your reaction speed and see how it affects total stopping distance. Average is 0.7 seconds — how fast are you? Results feed directly into braking calculations.
Test ReactionDaily Driving Safety Report
Real-time safety scores for 280+ NZ locations. Combines weather, visibility, temperature, wind speed, and grip conditions into one clear safety verdict for your area.
Check My AreaFollowing Distance Calculator
Calculate the safe gap at any speed. Adjusts for weather, road conditions, and reaction time. Based on real physics, not rules of thumb.
Calculate GapFind the right tyre for your vehicle. Scan your sidewall, compare sizes, search specs, or explore alternatives that fit your rims.
AI Tyre Scanner
Point your camera at any tyre sidewall. Multi-engine AI (Google Vision + GPT-4 + Claude) reads size, brand, DOT code, and condition using consensus voting.
Scan a TyreTyre Kicker Search
Search 120,000+ tyre patterns by size. Compare EU fuel and wet grip grades, UTQG treadwear, traction, and temperature ratings across brands — all in one view.
Search TyresAlternative Size Finder
Enter your current tyre size and see every compatible alternative. Colour-coded by WOF compliance: green for ±2.5% diameter, red for outside range.
Find AlternativesTyre Size Calculator & Visualiser
Compare any two sizes side by side. See the exact difference in diameter, width, sidewall, circumference, and speedometer error with a visual overlay.
Compare SizesQuick reference for tyre codes, ratings, and conversions. Decode what's printed on your sidewall in seconds.
DOT Tyre Age Calculator
Enter your 4-digit DOT code to instantly decode manufacturing week, year, and factory. Checks against 1,156 factory codes and flags tyres past the 6-year threshold.

PSI Reference Chart
Quick reference for common tyre pressures in PSI, kPa, and BAR. Covers the 20–50 PSI range with instant conversions. Just look up your number.
View ChartCheck if your tyres can handle your load, compare long-term costs, and verify towing safety before you hitch up.
Load Rating Upgrade Calculator
Changing tyre sizes? This tells you the minimum load index your new tyres need to match your original weight capacity. Essential when upsizing or downsizing.
Calculate LoadTyre Life Cost Calculator
Compare up to 3 tyres by price and expected lifespan. See the true cost per kilometre — because the cheapest tyre isn't always the best value over time.
Compare CostVehicle Load Calculator
Check front and rear axle loads against tyre capacity. Enter vehicle weight, cargo, and passengers to see if your tyres are rated for the job.
Check LoadTowing Load Calculator
Enter vehicle, trailer, and tongue weights to check if your tyres can safely handle towing. Calculates per-tyre loads and flags when you're near capacity.
Check TowingMake sure your tyres pass the Warrant of Fitness. Check axle compatibility, tread depth, and NZ-specific rules.
WOF Axle Compatibility Checker
Check if your tyres meet NZ WOF and Australian Roadworthy requirements. Same size, pattern, and construction on each axle — instant pass/fail.
Check AxlesNZ WOF Tyre Requirements
Everything about WOF tyre rules: tread depth minimums, age limits, damage thresholds, and axle matching. With photos showing pass vs fail examples.
