Firestone tyres have been sold in New Zealand almost since the first cars arrived here from the United States, not long after Harvey Firestone began making tyres in Akron, Ohio in 1900. In 1988 the Bridgestone Corporation purchased Firestone as part of its worldwide tyre family.


We have tyres for new cars, used imports, four-wheel drives, utes and vans. We've got a range of different brands, from Firestone and Bridgestone right through to our economy lines, Supercat and Primewell.

Because we’re an independent dealer, we can also source and supply any other brand of tyre. We are the Cooper Tires agent in Rotorua, so if you want to read more about these American made tyres, check out our Cooper Tires page.

If you’re after Toyo, Maxxis, Yokohama, Dunlop, Goodyear, Federal, BF Goodrich, Michelin, Continental, Hankook, Kumho, Pirelli, or anything else, just let us know and we’ll be able to get it for you.

Find your tyre size

If you ring up for a price on your tyres, you will always be asked what size it is. Usually the question we get next from a lot of people is “where do I find that?”. It’s found on the sidewall of your tyre and the numbers can be confusing if you don’t know what they mean. But it is quite simple once you know how.

Say for example, your tyre size is 205/65R15 94H

  • 205 is the width of the tyre in millimeters
  • 65 is the height of the sidewall, expressed as a percentage of the width of the
    tyre, i.e. 65% of 205 millimeters
  • 15 is the diameter of the wheel in inches
  • 94 is the load rating
  • H is the speed rating

Different tyres have different load and speed ratings and it is important that you match them up. It is a WOF requirement that the 2 tyres on each axle must have the same speed rating, and the load rating must be within 2 points, so if you have one tyre that is 94H and the other is 91H, you would fail your WOF even if they are both brand new tyres. That’s why, if you tell us you are just after 1 tyre, we will always ask you what the load and speed rating is on the other tyre so we can match it all up for you.

Run Flat Tyres

Some newer vehicles don’t come equipped with a spare tyre, but are instead fitted with run flat tyres. These tyres are designed so that if they get punctured, they can be driven on for a short while until they can be repaired. These tyres require specialist knowledge on how to fit these back onto the car, and all our staff at Simmonds Tyres are experienced in Run Flat Tyre Technology.

Bridgestone Ecopia

At Simmonds Tyres we are very pleased to be able to supply the Bridgestone Ecopia tyre. It is an eco-friendly, “green” tyre, designed to roll along the road easier than a normal tyre, which reduces your vehicle’s carbon dioxide emissions and helps with reducing your fuel consumption.

Check out Simmo’s tyre tips about “lower rolling resistance” and what it all means, and what steps you can take to make your vehicle more environmentally friendly.

Another step you can take to make your car more “green” is to fill your tyres with nitrogen. It also assists in reducing the rolling resistance of your vehicle which is so important.
