You can use this handy tool to test. Here, I’m assuming a 11-36 cassette, and comparing a 32 vs 34 with 42-622 tires. Oddly, there’s no option for 44-622, but RH tires run a bit smaller than labeled. http://www.gear-calculator.com/?GR=DERS&KB=34&RZ=11,13,15,17,19,21,24,28,32,36&UF=2230&TF=90&SL=2.6&UN=MPH&DV=gearInches&GR2=DERS&KB2=32&RZ2=11,13,15,17,19,21,24,28,32,36&UF2=2230
Here, I keep the 32, but change to a 54-622 tire: http://www.gear-calculator.com/?GR=DERS&KB=32&RZ=11,13,15,17,19,21,24,28,32,36&UF=2295&TF=90&SL=2.6&UN=MPH&DV=gearInches&GR2=DERS&KB2=32&RZ2=11,13,15,17,19,21,24,28,32,36&UF2=2230 Get the bigger chainring!
