The table is filtered to researched tyre sizes: 225/50 R17, 245/40 R18, 245/35 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.

The researched tyre sizes for this 2018 Audi A4 guide are 225/50 R17, 245/40 R18 and 245/35 R19. Those are the only sizes used in this shortlist, and they are treated as exact matches only. Fitment can still vary by trim, wheel option, market and any previous wheel changes, so this page should be used as a comparison guide rather than a universal answer for every car. Before you order, confirm the size on the current tyre sidewall or on the vehicle placard.
After you have matched the size, compare the tyres by season, price, stock and delivery. The shortlist is summer-only, which makes it most relevant for warm-weather replacement rather than winter or all-season buying. The matched options also sit at different price points: ContiSportContact 5 225/50 R17 94W Summer starts from £112.52, ContiPremiumContact 2 225/50 R17 98V Summer from £130.32, ContiPremiumContact 2 225/50 R17 98H Summer from £137.76, EcoContact 6 225/50 R17 98Y Summer from £112.52, and P Zero PZ4 SC 245/35 ZR19 93Y Summer from £171.50. Brand familiarity may matter too, because the shortlist is mostly Continental with one Pirelli alternative. If you are comparing the 225/50 R17 fitment, you have the broadest set of exact-match choices here, while the 245/35 R19 option sits at the premium end of the range and may need closer stock and delivery checks.
Start with the sidewall on the tyre that is already fitted to the car, then check that against the vehicle placard before comparing any products. If your Audi A4 matches 225/50 R17, 245/40 R18 or 245/35 R19, compare only exact-size products from the shortlist. Next, check the load index and speed rating, because the same size can appear in different rating combinations such as 94W, 98H, 98V and 98Y. If run-flat construction matters to you, only rely on it when both the car and the listing clearly support it. Finish by checking stock and delivery terms with the retailer, since availability and timing can change after the price is shown.
A 2018 Audi A4 is not a one-size-fits-all fitment. Trim, wheel option, market and any previous wheel changes can all alter the correct tyre size. That is why the guide separates the researched sizes into 225/50 R17, 245/40 R18 and 245/35 R19 instead of treating the model year as a single answer. If you are unsure, the safest check is the tyre sidewall first, then the placard, before you place an order.
Every tyre in this shortlist is a summer tyre, including ContiSportContact 5 225/50 R17 94W Summer, ContiPremiumContact 2 225/50 R17 98H Summer, ContiPremiumContact 2 225/50 R17 98V Summer, EcoContact 6 225/50 R17 98Y Summer and P Zero PZ4 SC 245/35 ZR19 93Y Summer. That makes the page useful if you want a summer replacement that matches your car’s size, but it does not say anything about winter or all-season superiority. Use season as a filter only after fitment is confirmed.
Even when the size is correct, the specification still matters. The 225/50 R17 group includes 94W, 98H, 98V and 98Y versions, so two tyres with the same sidewall size may not be interchangeable for your car. Compare the ratings that the vehicle requires before you focus on price or brand. Run-flat markings should be treated as a separate check and only used when both the car and the listing clearly support them.
This shortlist is best used as a value comparison between exact matches, not as a winner’s list. Four of the five tyres are Continental and one is Pirelli, so the price spread is a useful way to compare familiar brands across the exact sizes shown here. The lowest starting price in the shortlist is ContiSportContact 5 225/50 R17 94W Summer at £112.52, while the P Zero PZ4 SC 245/35 ZR19 93Y Summer sits at the higher end from £171.50. If your car uses 225/50 R17, you have more Continental options to compare; if it uses 245/35 R19, stock and delivery checks become even more important because the exact-match choice set is narrower. For any tyre size here, use price as the final tie-break only after size, load index, speed rating and season have all been checked.

Yes. The researched sizes for this guide are 225/50 R17, 245/40 R18 and 245/35 R19, but trim, wheel option, market and previous wheel changes can alter the correct fitment. Check the current sidewall and the vehicle placard before ordering.
Check the tyre sidewall first, then compare it with the vehicle placard. If the car has had wheel changes, rely on the actual fitment on the car rather than the model year alone, and confirm the load index and speed rating as well.
Because it is a fitment-led shortlist, it only includes tyres that match one of the researched sizes exactly. That keeps the comparison focused on the tyres that are relevant to your car, rather than guessing near sizes that may not suit it.
Yes. The shortlist is summer-only, so it is a starting point for warm-weather replacement only. If you need winter or all-season tyres, confirm your exact size here first and then search by the season you actually need.
Once the size matches, compare the load index, speed rating, season, stock and delivery terms. Those details can differ even between tyres that share the same sidewall size, so they are important final checks before you buy.
