Check the tyre sidewall for the size (for example, 225/50 R17) and confirm it against the driver door sticker or owner handbook. If your GS 300h has different front and rear sizes, make sure you enter each axle correctly when searching.

Registration lookup is a good starting point because it matches tyres to the vehicle record, but it may not reflect changes like aftermarket alloys. If the results do not match what is fitted, search by tyre size from the sidewall and compare load and speed ratings.

Not necessarily, but the GS 300h benefits from tyres with the correct load rating and strong wet braking, plus low rolling resistance and lower noise for refined cruising. Always match the ratings recommended for your specific wheel and trim setup.

Yes, after choosing tyres you can select a nearby fitting garage and pick an appointment time. Fitting typically includes mounting, balancing and disposal of the old tyres, while services like wheel alignment or TPMS work may be offered separately by the garage.

All-season tyres can be a practical year-round choice for most UK driving, while winter tyres suit drivers who regularly face cold temperatures, ice or snow. For best handling and stability, fit the same type across all four wheels and keep tread depth well above the UK legal minimum.
