JARGON BUSTED 

XL – Extra Load (stronger casing, higher pressure capability

PERFORMANCE = Enhanced grip and handling for higher speeds, balancing sportier response with daily usability..
SUV = reinforced construction for heavier vehicles, offering stability, load capacity, and control for SUVs and crossovers.
ROAD = everyday road use, focused on comfort, stability, noise reduction, and predictable handling.SI / SEAL INSIDE: A sticky sealant layer inside the tyre automatically seals small punctures (typically up to ~4 mm) caused by nails or screws.
3PMSF / M+S — all-season/winter capability

ELT / Elect = tyres engineered for electric and plug-in vehicles, designed to handle higher torque, reduced noise, increased load, and efficiency demands.
NCS / NC0 — Noise Cancelling System tech

AO / VW / J / LR / MO / VOLVO — OEM homologation codes (Audi, VW, Jaguar, Land Rover, Mercedes, Volvo)

FSL — Full Sidewall Lettering

Run-Flat — some 19″/20″ sizes include RFT variants

LOAD AND SPEED RATINGS BRIEFLY EXPLAINED
Load Rating (the number)
This number tells you how much weight ONE tyre can safely carry
The higher the number, the more weight it supports
All four tyres together must safely support the full vehicle weight
