JARGON BUSTED

In 2026, Irish drivers generally choose between two main options based on their year-round needs:
Summer Tyres: Optimized for maximum performance and safety when temperatures are above 7°C. While standard in Ireland, they lose grip in freezing conditions.
All-Season Tyres: A versatile hybrid designed to work safely from -10°C to 30°C. They offer a reliable compromise for dry, wet, and lightly snowy roads without the need for seasonal changes.
Because Ireland’s temperate climate rarely sees extreme snow, many drivers use summer tyres year-round, though all-season tyres are increasingly popular for added winter security.

Notes:
RFT denotes Run-Flat Technology.
XL is Extra Load.
AO (Audi Original), MO (Mercedes Original), PE (Peugeot Original Equipment), LR (Land Rover Original Equipment), and BMW OE are manufacturer-specific original equipment fitments.
Most of these sizes implicitly include rim protection (MFS/FP) features, which are standard for performance SUV tyres in this diameter.

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

Rule: Always match or exceed the vehicle’s required load rating.
Rule: Never fit a lower speed rating than the manufacturer specifies.
