There are as many varieties of tires as there are bikes.
There are tires for the front, back, wet/dry, winter conditions and the tire who wants to do it all.
So for me to say “this tire is the best!” might not be in your best interests. Each of us rides in different conditions.
Some of us live where it rains frequently. Others of us live where the sun is rarely hidden.
Since all circumstances are different, to say one is the best is not practical.
I am going to present the information. It is up to you to decide what is best for your circumstances.
A word of caution, skimping on tires is not a good idea! Your tires can make or break you in a race.
Here is a list of the major brands:
Michelin Continental Hutchinson Vittoria
For those who are wet weather riders. You could use a slightly wider tire for better traction in the turns. A bit of information I have picked up.
Michelin has some outstanding tires to choose from. The Pro Racer 2 is a good all around tire. It works well in wet and dry conditions.
I have found Continental tires to work well in dry conditions.
The Grand Prix provides a nice ride in dry conditions. Not the best in wet conditions though.
Vittoria also has some outstanding tires. The Open Corsa is a very good all around tire.
It has hard rubber in the center and softer on the sides. The softer side rubber is for improved cornering.
The newest Hutchinson’s tire is a tubeless one. It is called the Fusion2.
Like the Vittoria, it has hard center rubber and soft side rubber. The Fusion2 works well in wet and dry road conditions.
The tires I have just mentioned are primarily for training and everyday riding.
Racing tires are different creatures all together. Racing tires come in different sizes, meaning width, for the front and back.
The front is narrower, lighter and has softer/stickier rubber for better cornering. The rear tire has harder rubber for better rolling resistance.
You can find a great set of racing tires from Continental. Their Attack/Force racing set is a hard combo to beat.
You can take this general information and decide from here what is best for you. The knowledge about the best road bike tires is in your hands. Make the best of it!
