Reading your tyre size for mobile tyre fitting

How to read your tyre size before contacting our mobile tyre fitting service

Before we can arrange our mobile tyre fitting service we need to know the right tyres to bring to you! You might have noticed that we ask for a string of numbers and letters on our contact form. That’s so we can be sure that we are bringing the right tyre to you. Many companies try and get this information by asking for your registration plate but that’s not always accurate and as you know here at We Fix Alloys we like to make sure our customers get great service and that means getting it right!

If you look on the side of tyres you can get a whole lot of useful information, including the manufacturer, product name load and PSI rating but right now what we’re interested in is the size, load and speed rating. That will look like this on the side of your tyre. So grab a pen and paper and go and make a note of it before you fill in the contact form here
