Yes. Mk1, Mk2 and Mk3 Audi TT models can use different widths, profiles and wheel diameters, and performance trims like TTS and TT RS often differ again. Use your registration in the search tool or confirm the size on the driver door placard and current tyre sidewall before ordering.
Some Audi TT versions and wheel packages run wider tyres on the rear than the front. If your TT is staggered, tyres must be bought in the correct front and rear sizes, and you should avoid rotating front to rear. A reg search will highlight the correct fitment for your car.
Your tyres must meet or exceed the manufacturer-recommended speed rating and load index for your TT. These are shown in the handbook, on the door placard and on the existing tyre sidewall. If you are unsure, use the reg lookup so the results match your car's required specification.
Only if your vehicle setup supports it. Run-flat and standard tyres can feel different and should not be mixed on the same axle. Check whether your TT has a spare wheel, space saver or tyre repair kit, and consider ride comfort versus puncture mobility before choosing.
After selecting tyres that match your Audi TT, you can book fitting at a local UK garage at a time that suits you. The fitter will replace the tyres and can advise on balancing and alignment if you have uneven wear or steering vibration. Always ensure your tyres meet the UK legal tread depth of 1.6mm across the central three-quarters of the tread.
