What to Check Before Buying Tyres Online

The short version. A quick pre-order checklist for buying tyres online: confirm the size, ratings and date, check the fully-fitted price and what it includes.

Buying tyres online is straightforward, and a short run of checks before paying keeps it that way. None take more than a minute, and together they head off every common online-buying mistake.

Confirm the tyre

First, that the tyre itself is right:

  • Size: cross-check a registration lookup against the actual sidewall, since the plate gives the factory size, not what is fitted
  • Load index and speed rating: match or exceed what the car needs
  • Season and type: summer, all-season or winter, and any run-flat requirement
  • Genuinely new and fresh: a recent date code, not old stock or a part-worn sold loosely

Confirm the price

Then, that the price is the real price:

  • Look for a fully-fitted price, the tyre plus fitting, balancing, valve and disposal
  • Check what is included so nothing is added at the counter

A fully-fitted price, the kind an online tyre seller like Tyres.co.uk quotes, with a lifetime guarantee behind every tyre, covers fitting, balancing, a new valve and disposal, which makes the total easy to compare honestly rather than guessing at the extras. The fuller list of things to look for when buying goes into each.

Confirm the fitting

Finally, that it can actually be fitted conveniently:

  • A fitting location near home or work
  • A time slot that suits, confirmed before paying
  • Or a mobile fitter to come to the car

There is no point ordering tyres that then sit waiting for a slot weeks away. Lining up the fit as part of the order avoids it.

And the reassurance

A last glance at the guarantee and returns, and any reviews, rounds it off. With the tyre, the price and the fit all confirmed, ordering online is quick and safe.

From the workshop: the two slip-ups I see are ordering the factory size when the car's on aftermarket alloys, and comparing a bare tyre price against someone else's fitted price. Check the sidewall, and compare fully-fitted to fully-fitted. Do those and you'll never be caught out buying online.

Sources and accuracy. This reflects sound online-buying practice at the time of writing. Inclusions and policies vary by retailer. If anything here looks wrong, get in touch and we will check it and put it right.

Common questions

What should I check before ordering tyres online?+

That the size and ratings match your car, the tyre is new and recently made, the season suits you, and the price is fully fitted with the inclusions clear. Then confirm the fitting location and time work, and that there is a guarantee. A couple of minutes of checks avoids the common mistakes.

How do I make sure I order the right tyre size online?+

Start with a registration search for the likely size, then confirm it against the sidewall of the tyre actually on the car. The two match for standard cars; on modified wheels the sidewall wins. Ordering to the sidewall size is what guarantees a fit.

What does fully-fitted price mean?+

It means the price includes fitting the tyre, balancing the wheel, usually a new valve, and disposing of the old tyre, not just the tyre on its own. Comparing fully-fitted prices is the only fair way to judge the real cost between sellers.

Should I check fitting availability before buying tyres online?+

Yes. Confirm a fitting location near you and a time slot that works before paying, so the tyres are not sitting waiting. Most online retailers show available garages and slots as part of the order, which makes it easy to line up.
