700x42c Tire Size In Inches (WARNING!)

Warning: Do not convert tire sizes from millimeters to inches. Read on for more details.

Tracking down the correct size of bike tire for your wheels can be incredibly time-consuming and frustrating. So, if you’ve been researching this and getting more and more confused, then you’re not alone.

There are many tire sizing systems in use throughout the world (your wheels are measured in millimeters) and unfortunately, it’s not a simple task of converting from one to the other. My advice is to stick with the tire size you have and pick a replacement tire with the same measurements.

But don’t worry, I’ve got some recommendations for you in a moment. Two great tires and two fantastic inner tubes (because it’s always worth having a spare tube in case of blowouts).

Anyway, there’s no time to waste, so let’s go!

Stick with the same size of tire. My recommendation is the Continental Contact Plus All-Terrain 700x42c Tire


These are my recommended 700x42c tires for your bike

Once you’ve determined your bike tire size (which is often the first hurdle) the next step is to decide what sort of riding you’ll normally be doing.

The choice here is between:

  • Riding on mixed surfaces, some paved trails mixed with looser dirt and gravel tracks, generally a hybrid or mountain bike
  • Purely paved trails and roads, going as fast as possible, normally on a road bike

Mixed surfaces

Continental Contact Plus 700x42c Bike Tire

This is a fantastic all-rounder from Continental tires that is the perfect size for your bike and the ideal choice if your cycling is on mixed surfaces.

Continental have been manufacturing rubber tires since the 19th Century so, it’s fair to say, that they know how to make a quality bike tire. And the Contact Plus certainly lives up to the Continental name with a ton of positive reviews that mention excellent grip on a range of paved and non-paved surfaces, low rolling resistance (so you can go faster with less effort), and resistant to punctures.

Regarding the grip, take a close look at the pictures at the Amazon link below and you’ll see something interesting.

Along the center of the tire, you have an unbroken strip of rubber running all the way around the tire. This gives the smooth rolling that you want on paved roads and trails (knobbly tires would give lots of unpleasant vibration on these surfaces). Moving sideways on the tire you then get an open grip pattern. This gives you the grip you need when you’re cornering on looser surfaces, like gravel. Finally, there’s a reflective circle running around the tire which goes just above the wheel rim. Excellent for side-on visibility for you and your bike.

A great package and perfect for your bike.


Paved trails and roads

Continental Contact Speed 700x42c Bike Tire

As a great man once said, “I feel the need, the need for speed”. And that’s what you’re going to get with these tires from Continental.

If you know that you’re just going to be using your bike on smooth paved surfaces then you can dispense with just about all those knobbly grips and go with a tire that is (almost) as smooth as a baby’s behind.

Whilst the tire does have some low-profile grip, this is more designed to hurl you and your bike even faster along the trails. Got somewhere you need to be? Fast?? Got another cyclist in your sights up ahead? If the answer’s “YES!” then these tires are the ones for you.

The ideal choice for city biking on single speed or fixed gear bikes. Or out in the country on roads.


These are my recommended 700x42c inner tubes for your bike

Whilst you’ve got tires on your mind right now, it’s also worth considering inner tubes as well.

Changing a bike tire is a simple job, but it’s useful to have a spare tube by your side in case you end up holing the existing tube when you’re taking the old tire off or fitting the new one.

Plus, I’d always recommend taking a spare, puncture repair kit, and a mini bike pump out with you on a bike ride. Punctures happen and it’s good to be prepared.

The inner tubes below are both excellent products and the perfect size for your bike. The choice here is which tube valve you go with. Best practice is to stick with the same valve as you have now. That way you’re bike pump will fit fine.

For Schrader valves, which are the car tire short stubby ones, go with this tube in size 700×35-43:

For Presta valves, which are longer and slimmer European style of valve, go with this great tube in size 700 x 35-43.
