No matter what type of bike you ride, having the correct tire pressure is critical for getting the best performance from your tires and bike out on the road or trail. These days, we’ve got quite a few options when it comes to tire pressure recommendations, with numerous brands offering their versions of pressure calculators online and/or in app form. Wolf Tooth Components is among the brands helping riders take the guesswork out of tire pressure with its Tire Pressure Calculator App, launched back in 2024.
Just a few months later, Wolf Tooth updated the Tire Pressure Calculator to version 2.0, adding more tire sizes and addressing rider requests. Now, with version 2.1, Wolf Tooth is trying to stay on top of the evolving tire market while addressing recent trends in mountain and gravel bike tires. Let’s check out the updates.
What’s New For v2.1?
The appearance and user interface of the Wolf Tooth Tire Pressure Calculator app haven’t really changed and still let you find your ideal tire pressure based on wheel size, tire width, rider weight, temperature, and other factors. Now its been fine-tuned with more options than ever to dial in your ride. These are:
MX/Mullet Option for MTB
Previously, when choosing wheel size in the Mountain (Advanced) mode, you could choose wheel size, but it did not allow you to select front and rear independently to account for mixed wheel configurations. Now, rather than defaulting to both wheels being the same size, you can choose front and rear wheel diameters separately. This small change should make it easier for the many riders on mullet/MX/mixed-wheel mountain bikes to dial in their tire optimal pressures.
Radial Tire Casing Option for MTB
Schwalbe put the mountain bike tire market on notice a couple of years ago when it debuted its Radial casing tires. The enhanced traction from the radial casing construction was and is notable, as are the counterintuitively higher pressures that the tires require to perform at their best. Adding pressure to a tire to increase grip is confusing at first, so this could be helpful for folks as they try out radial tires.
Given the performance and high praise that Schwalbe’s Radial tires have received, it also seems very likely that we’ll be seeing more MTB tire brands coming out with their own radial casing tires. We’ve already seen some from Vee Tire Co., and we expect more brands to follow suit. Adding the Radial option seems like a good move by Wolf Tooth that will hopefully smooth the transition.
32” Tire Option for Gravel and MTB
Based on all the hype surrounding the 32” wheel size, Wolf Tooth is getting ahead of the curve and including 32” as a wheel diameter in the Advanced modes for both Gravel and Mountain tires. While this is likely to only benefit a select few early adopters of the larger hoops at first, it will surely become more useful as industry and rider acceptance (potentially) grow in the coming years.
Casing Width Units Options for Gravel
Since some modern gravel tires are just mountain bike tires with widths measured in inches, Wolf Tooth added the option to use inches for the width measurement on the Basic and Advanced Gravel modes. Now, you can choose between width in millimeters or width in inches, depending on the tires in question.
Up to 3.3” Width for MTB Tires
The plus-sized tire phenomenon came and went, but there are still some mid-fat tires out there. Wolf Tooth has increased its mountain bike tire widths to go all the way up to 3.3” wide for those who might still be hanging on to the hope that 27.5”+ and 29”+ could make a comeback.
