The table is filtered to researched tyre sizes: 195/65 R15, 205/55 R16, 215/55 R16, 215/50 R17, 225/45 R17, 225/40 R18. Compare the listed size against the current tyre sidewall first, then check load/speed rating, season and run-flat notes. Products outside those researched sizes are deliberately excluded from this vehicle shortlist.

This shortlist is built around researched exact sizes only: 195/65 R15, 205/55 R16, 215/55 R16, 215/50 R17, 225/45 R17 and 225/40 R18. Fitment can change with trim, wheel option and market, so the model year alone is not enough; confirm the current tyre sidewall or vehicle placard before you buy. The Tyres.net shortlist here is made up of five summer car tyres from Pirelli, Continental, Hankook and Nexen, so it is useful for size-matched comparison rather than a universal fitment promise.
Once the exact size is matched, the main trade-off is price versus brand familiarity and variant coverage. In the supplied set, Hankook 195/65 R15 options start from £49.85, while Pirelli and Continental 205/55 R16 options begin around £75.80-£77.36, so the gap is meaningful if your Astra is on 15-inch or 16-inch wheels. Stock and delivery still need checking on the retailer page, and a cheaper tyre is only a sensible buy if its size, load index and speed rating also line up with the car.
Start with the sidewall or vehicle placard, not the model name, then match the exact size shown on the tyre listing. If your Astra is on 195/65 R15, the two Hankook summer options in this shortlist are the lower-cost route, with the Kinergy Eco 2 K435 starting from £49.85 and the Kinergy Eco K425 starting from £65.64. If you need 205/55 R16, compare the Pirelli Cinturato P7 from £75.80, the Continental EcoContact 6 from £77.36 and the Nexen N blue HD Plus from £59.52, then weigh brand familiarity against current price and availability. After that, compare the load index and speed rating printed on your current tyre against the product page, and check whether your car currently uses run-flat tyres before assuming a regular summer tyre is suitable. Season is a secondary filter here because every shortlisted tyre is a summer tyre, so the real choice is between exact size, brand, price and current stock.
A 2018 Vauxhall Astra can wear different tyre sizes depending on trim, wheel option, market and even whether a previous owner changed the wheel package. That is why the researched groups are kept separate: 195/65 R15 and 205/55 R16 are not treated as interchangeable, and the wider Astra families in 17-inch and 18-inch fitments should be compared on their own terms. If the sidewall, placard and handbook do not all point to the same size, stop and verify before ordering.
The shortlist has no visible review averages or review counts, so there is no review-based ranking to lean on here. Live retailer pages also returned limited product-page detail, which means shoppers should verify the latest price, stock and delivery before purchase rather than assuming the current listing will stay unchanged. Because of that, this page works best as a cautious comparison guide: exact size first, then brand, then price and availability.
Before ordering, confirm the tyre size against the vehicle placard and the current sidewall, then check the product listing for load index, speed rating and any notes about run-flat construction if your car has them. If your Astra has had wheel changes, compare the fitted wheel size with the researched groups on this page, because a 15-inch tyre, 16-inch tyre, 17-inch tyre and 18-inch tyre are separate decisions. If anything conflicts, a tyre fitter can help confirm the correct match before you commit.
The best value here is the tyre that matches the car correctly and still fits your budget after delivery and fitting costs are added. In this shortlist, Hankook’s 195/65 R15 options sit below the Pirelli and Continental 205/55 R16 options on price, while Nexen gives a lower-cost 205/55 R16 alternative to compare against the premium brands. Use the £49.85-£149.27 spread as a guide only, then check the latest retailer price, stock and delivery before you buy.

Yes. The researched fitments include 195/65 R15, 205/55 R16, 215/55 R16, 215/50 R17, 225/45 R17 and 225/40 R18, but which one applies depends on trim, wheel option, market and any previous wheel changes.
Check the current tyre sidewall first, then compare it with the vehicle placard and handbook. The size on the car should match the product listing exactly before you order, including the load index and speed rating if shown.
Yes. The shortlist here is made up of summer car tyres from Pirelli, Continental, Hankook and Nexen, so it is a summer-only comparison. If you need another season, you should search separately rather than assuming these are interchangeable.
Check load index, speed rating, whether the car currently uses run-flat tyres, and the latest stock, delivery and fitting costs. If the sidewall and placard disagree, or the wheel package has changed, ask a tyre fitter before ordering.
Treat 17-inch and 18-inch setups as separate fitment groups, not as substitutes for 15-inch or 16-inch tyres. The researched Astra families include 215/50 R17, 225/45 R17 and 225/40 R18, so use the current sidewall or placard to confirm which one your car actually needs before buying.
