Is it a good idea to get a narrower front tire and a wider rear tire on a road bike?

6 min read

Asked by: David Maignan

In most cases, a wider tire will provide better traction, so it makes sense to run a larger front tire. (While you still need traction from the rear tire, it’s usually not a big deal when the rear tire loses a little traction. However, if the front tire loses traction, you could be in big trouble!)

Can you have different size tires on front and back of bike?

It’s perfectly okay to run different sizes, brands, and types of tires on the front and rear. As you note, rears will wear faster due to carrying more of the load. The grip threshold is largely irrelevant, since the front and rear will be exposed to different forces and grip requirements.

Is it OK to have different size tires front and back?

No matter what type of vehicle you have, having mismatched tires front to back can sometimes cause handling problems. Granted, this really doesn’t happen that often, and it is usually no problem to have different tires on a car.

Is it better to have wider tires in the front or back?

That said, run the larger on the rear. The higher air volume will make for a more comfortable ride, and the narrower front tire will steer quicker, which makes for more reactive handling, and has a better aero profile, (which may or may not matter to you).

Should both bike tires be the same size?

Bicycle wheels can handle a range of different widths, so it’s not absolutely necessary to replace your tires with one with the exact same width. In fact, there are often advantages to using a tire that is a little wider, as long as your bicycle has adequate clearance to handle the larger size.

Can I use two different width tires?

Having two different-sized tires on the same axle is generally not a good thing. If the diameter of the two tires is close, then the rolling radius is about the same, so in the short term, you probably won’t have any damage, but long term, you run the risk of messing up your car’s differential.

Are bigger rear wheels better?

Advantages of larger rear wheels in an RWD car? Having a larger diameter rear wheel increases the amount of rubber that contacts the road along the axis of the vehicle which increases your acceleration potential. When you accelerate, much of your vehicle’s weight shifts to the rear.

Do front and rear tires need to match?

For optimal safety and performance, Continental recommends fitting the same tires to every wheel position on your car, so drivers should have the same brand, size, tread pattern, load index, and speed rating on the front and rear tires.

Is it OK to mismatch front and rear tires?

A car with mismatched front and back tires should still be usable, especially if it is a two wheel drive vehicle. Tires wear out at different rates, and if one is more worn than the other, simply rotating the tires may be a possibility to prevent further wear.

Why are rear tires wider than the front?

Quote from video: So the rear tire sees large amounts of load from putting power to the ground and from the load transfer that happens when accelerating.

Is it better to use a smaller tire at the front and bigger on the back on a front wheel drive?

While it’s fine to put narrower tyres on the front and wider on the back, it’s pointless to put wider tyres on just one side of the car. This would change the weight balance and would mean one side of the vehicle would grip differently to the road when braking. It would change the cornering dynamic, too.

Why are front tires narrower than rear tires?

Since the motor drives the rear wheel and forces it in a forward direction the downward force to the rear tire needs to be greater than in the front. So bigger tires and more body weight over it equals more traction better power transfer.

Why do cars have wider tires in the back?

You may also notice that some enthusiasts instead choose a much wider tire for the rear axles as compared to what they put up front. The theory behind this is that it gives you as much rubber as possible to transmit power to the pavement, thus ensuring excellent traction for higher horsepower, rear-wheel drive cars.

Does tire width matter bike?

While tire diameter should be an exact match, you do have the option of putting on a tire with a slight variation in width. Some riders opt for wider tires, for example, to give them more traction and a somewhat cushier ride.

How much difference in tire size is acceptable?


When changing tire sizes, we recommend staying within 3% of the diameter/height of the original tire. Any more than this and you face the risk of brake failure.

Can wrong size tires damage transmission?

Can you mix wheel size on a bike?

The short answer is to realizability: Nothing precludes you from mixing wheel sizes provided the wheels fit in and clear everything and you can adjust the brakes to work (typically easier with disc brakes, hard with most rim brakes).

Can you mix tyres on a bike?

Usually yes, it’s not illegal to mix motorcycle tyres but it’s not ideal. On the road it’s illegal to put a crossply tyre on the rear with a radial on the front, but not the other way round. The speed rating should also be enough for the bike’s maximum speed, not the speed you normally ride it at.

Can you put different size wheels on a bike?

As long as you pay attention to the correct diameter size for your rim, and make sure that your frame has enough clearance, you should be able to put bigger, wider tires on your bike with no problems.

Can you put different tires on a bike?

The answer is yes, by all means, on almost any bike, you can choose tires that are best for the type of terrain that you ride.

Do front and rear tires need to match motorcycle?

Motorcycle tires are not interchangeable. There is a specific front tire and back tire, and pairs of motorcycle tires are developed and tested together. Mixing the tires on your motorcycle will reduce functionality and safety.

Can you put a wider tire on a narrow rim?

As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half inch (12.5 millimeters) increase in rim width.
