In the past, road bikes only required 100 psi tire pressure, regardless of riding style, weight, or road conditions. Now that we know that we can ride farther and faster only by setting the correct tire pressure, so how can we set the correct tire pressure? Through trial and error, some tire brands will provide tire pressure charts on the packaging or on their websites, but these are not accurate enough. Fortunately, with the tire pressure calculator, we can set the tire pressure accurately. There is a very useful tire pressure calculator in the SRAM AXS App, and now a tire pressure calculator is also provided on the Vittoria website, which is more detailed and has more adjustable parameters.

Choose a car model: mountain, road, gravel, etc.Road models are further divided into: TT, triathlon, road racing and road enduranceElectric assist is becoming more and more common, so options are also includedTire type also affects tire pressure. Although this is based on Vittoria tires as the standard, it is also applicable to other brands. From top to bottom they are: Cotton threadPlyCompetition tires, nylon ply competition tires, durable training tires, reinforced puncture protection tires. The thickness and hardness of the carcass will affect the tire pressure. Thicker tires can use lower tire pressures.Choose tire width, 28mm is already the mainstreamTubular tires, inner tubes, tubeless tires, lined tubeless tiresWhat you want from a tire: More responsiveness, balance, softerRider weight plus weight of car and equipment (67+7)Choose road conditions, from smooth to roughChoose road surface: Dry, Mixed, SlipperyThe framed one in the picture is BX’s choice. The calculated results are 62psi for the front wheel and 64.6psi for the rear wheel. It can be seen that Vittoria’s tire pressure calculation results are relatively aggressive, and are close to the calculation results of similar parameter settings in the SRAM AXS App. This is also in line with the current trend, with more and more riders realizing the advantages of low tire pressure. This tire pressure calculator is quite detailed. If it is lacking, it is the lack of rim width options, which also greatly affects tire pressure. Of course, this is easy to understand, because the tire brand still defaults to 21mm internal width as the standard. Hurry up and calculate the tire pressure you are using to see if it is set correctly.
