Hi,
I'm with the guys at ATS Euromaster and here's my advice for you.
Double & triple check your tyre sizing and requirements (do you want run flat etc?).
Then decide whether you're happy to fit the tyres yourself or whether you'd prefer to go to a garage to have them fitted... All of our tyres are fitted in your local centre. Finally if you're coming to a centre pick the time that best suits you.
I'd never suggest fitting the tyres yourself unless you're completely confident in your ability and that you'll align them correctly.
If you are going to a centre for fitting then check that the tyre prices online include fitting (no one likes a hidden charge!) All our online prices are fully fitted, but not all retailers do this.
Hope this helps,
Laura
