This can be a query that comes up loads from ESR members and it’s an excellent one. The reply is wider is healthier for all highway floor situations, however particularly for the variable highway surfaces you’ll encounter on the ESR route. Use the widest tire, with supple high-performance casings, your bike body will enable.
Vast tires make biking extra enjoyable, safer, and simply as quick as slender tires on clean surfaces and sooner on less-maintained and bumpier roads. Moreover, decrease tire pressures are rather more snug appearing as a mini shock absorber. The broader the tire, the much less stress required. Within the check under, the 44 mm tires have been inflated to 2.1 bar (30 psi); the 28 mm tires at 4.5 bar (65 psi).
Right here’s a tire check on actual roads, utilizing a down-hill coast with fixed velocity, on a day with no wind. Identical actual tire and casing on a 44mm vs a 28mm mannequin.
The outcomes:
28 mm: 27.636 km/h
44 mm: 27.564 km/h
