Replacements for worn tires with different patterns and construction will not react the same. Also, a new tire is stiffer than an old tire. The new tire has a rounder tread profile, different contact patch and ''lean-over edge'' than the worn profile of an old tire. The new tire will also not react the same in combination with its remaining tire. I Have a Tubed Tire.
Tubes are a critical part of a tube-type wheel assembly.
With a tubeless tire and tubeless wheel, the air is contained within the assembly. With a tube type rim and tire combination, it is the tube that contains the air. When fitting a new tire on a tube-type rim, a new tube should be fitted at the same time. Old tubes can become stretched and, if an old tube is fitted inside a new tire, it can crease or fold over itself and fail due to chaffing and thinning of the rubber. Always insure that the rim band is in good condition, that spoke ends do not protrude and are covered to avoid tube damage.
