The table is filtered to researched tyre sizes: 205/55 R16, 205/50 R17, 225/45 R17, 225/40 R18, 235/35 R19. 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 guide is built around five researched 2018 Audi A3 tyre sizes only: 205/55 R16, 205/50 R17, 225/45 R17, 225/40 R18 and 235/35 R19. The year can overlap generation changes, so trim, wheel option and market can change the correct size; that is why the shortlist is exact-match only, not a model-wide recommendation. Before comparing Continental, Nexen, Pirelli or Bridgestone options, confirm the size on your current sidewall or the vehicle placard and then check the retailer page for the latest price and availability.
With no visible review scores on the shortlist, the practical comparison is size, brand, price and availability rather than ratings. The visible prices run from £60.94 for the Nexen N blue HD Plus 205/55 R16 91V Summer up to £203.11 for the Continental ContiSportContact 5 P 235/35 ZR19 91Y Summer, while the Pirelli P Zero PZ4 SC 235/35 R19 reaches a higher visible benchmark range up to £292.40. That spread matters because the 16-inch choices are the budget-led starting point, while the 18-inch Bridgestone Turanza T005 and the 19-inch Continental or Pirelli options are separate exact-fit comparisons for drivers who already know their wheel size.
Start with the sidewall on the car, then check the placard or handbook so you do not mistake one exact fitment for another. After size, compare the load index and speed rating shown on the tyre listing against what is fitted now, and look for run-flat markings only if your current tyres are run-flat. Once those checks line up, compare summer-season options such as the Continental EcoContact 6 205/55 R16 91V Summer, Bridgestone Turanza T005 225/40 R18 92Y Summer or Pirelli P Zero PZ4 SC 235/35 R19 91Y Summer on current stock and delivery terms.
The 2018 Audi A3 is a good example of why model name alone is not enough. Public fitment pages show that the car can span multiple tyre sizes depending on trim and wheel package, with 17-inch, 18-inch and 19-inch fitments appearing alongside 16-inch options in the researched set. That means a previous wheel change can alter the correct tyre just as much as a original equipment trim change, so the safest buying habit is to compare the current tyre sidewall first and only then narrow by brand or price.
All of the shortlisted products here are summer tyres, so they should be compared as warm-weather choices rather than as all-season substitutes. For many shoppers, that means the key decision is whether a summer tyre suits the way the car is used most often, especially for commuting and motorway miles, rather than assuming one brand is automatically the smarter buy. If the car sees colder-weather driving, verify the season choice before ordering; then use visible factors such as brand familiarity, price and delivery rather than expecting one universal performance answer.
The shortlist covers a wide style range even though every option is an exact-size match. The 205/55 R16 tyres, including the Nexen N blue HD Plus 205/55 R16 91V Summer and Continental EcoContact 6 205/55 R16 91V Summer, sit at the lower end of the visible price range and are the easiest place to compare value if your Audi A3 uses 16-inch wheels. The 235/35 R19 Continental and Pirelli options sit at the sportier end, while the 225/40 R18 Bridgestone Turanza T005 gives a separate exact-fit choice in the middle, so the shortlist is useful for comparing fitment and use case rather than ranking one tyre across the whole car.
Value only starts once the tyre size is correct, because the cheapest option is not useful if it does not match the car. The visible shortlist gives you a narrow comparison set from four familiar brands: Continental, Nexen, Pirelli and Bridgestone, with prices spanning £60.94 to £203.11 on the visible product pages. Check the retailer page for latest stock, delivery cost and fitting options before ordering, because the live price and availability can move and the best choice may simply be the one that matches your exact sidewall size and fits your budget.

Yes. The researched fitments show five exact sizes for this model year, and the correct one can change with trim, wheel option, market and even previous wheel changes. Always check the tyre sidewall or vehicle placard on your own car before you compare products.
The best place to start is the current tyre sidewall, then confirm it against the vehicle placard or handbook. Match the full size exactly, then compare the load index, speed rating and season on the retailer page before placing an order.
The shortlist here is made up of summer tyres only, including the Continental EcoContact 6, Nexen N blue HD Plus, Bridgestone Turanza T005, Continental ContiSportContact 5 P and Pirelli P Zero PZ4 SC. If you need a different season category, verify that before buying rather than assuming a summer tyre is the right choice.
Yes. Exact size is only the first check: compare the load index and speed rating shown on the listing with the tyre already fitted, and look for run-flat markings only if your current tyres are run-flat. If anything disagrees, ask a tyre fitter to confirm the correct match.
