How to choose the right car tyre

How to choose the right tyre

There are many different variables to consider when choosing the right tyre. This could be as simple as choosing a tyre within your budget, or if you are doing high mileage it may be worth putting on a better quality tyre from our premium range. This will save you money and time in the long run as you will get more mileage from your tyres and you will save time in needing to have them changed more regularly.

When choosing the right tyre for your vehicle it is important to ensure that the correct size is fitted as changing the size or having different tyre sizes on your vehicle could cause mechanical troubles. If you would like to change the size but are unsure what to go for please get in touch with us and we will guide you in the right choice for you and your vehicle.

Living in the UK we experience all kinds of weather from the odd days of summer to the dark and cold winters. Finding the right tyres for the changing weather and differences in temperature is very important. Do you go for the conventional summer tyre that is most commonly sold? Or do you go for a all season tyre? Or even a winter tyre? If your unsure what is the best Tyre to go for please get in touch.

This is 65. It the sidewall height from the rim to the tread area of the tyre. It means the profile is 65% of the 185 section width.

Fitting a tyre with a lower speed rating can invalidate insurance.
