Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Are run-flat tyres needed on the 1998-2004 Opel Astra?
Most 1998-2004 Opel Astra cars were supplied with conventional tyres and a spare or repair kit. Only fit run-flats if your specific car was originally specified with them and has tyre pressure monitoring.
Where should I check the original tyre size for my Opel Astra?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
The Astra uses small wheels — does that affect tyre choice?
Smaller-rim cars (14" and below) usually have plenty of sidewall, which gives a softer ride and lower replacement cost. Mid-range tyres are often the best value here unless you do high-mileage motorway driving.

Common UK factory fitments for the 1998-2004 Opel Astra include 175/70 R14, 185/65 R15, 195/60 R15, 205/50 R16. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
What does the chassis code G mean for tyre choice?
