Found this chart that gives circumference of various wheel Tyre combos.
BikeCalc.com - How to calculate Bicycle Wheel Size
Done the calculations to work out the diameter and radius.
Now I have 27.5 x2.8 and want to change to 29 but what width Tyre ???
I’ll use my calculations below to work out if I got clearance ect.
Size.,, Cir.,, Dia.,, Radius
27.5x2.8,,, 2281.55,,, 726.24,,, 363.12
29x2.6. 2369.01 754.08,,, 377.04
29x2.5. 2353.05 748.99,,, 374.49
29x2.4. 2337.09 743.91,,, 371.95
29x2.35. 2329.11 741.37,,, 370.68
29x2.3. 2321.13 738.83,,, 369.41
29x2.25. 2313.15 736.29,,, 368.14
now I have got approx 20mm frame clearance and want to have approx 10mm clearace.
So a 29x2.5 will leave me with approx 9mm clearance. Also raising the bottom bracket 11.37mm.
Wonder how this would affect the handling of the bike being higher ?
Different brands and treads will measure different, but at least the above will give a bit of an indication when making the swap.
Now I need me some pie
