sirs... do we have plus-size tires here in the Philippines? if so... can a 27.5x2.2 tire be replaced by 27.5x3.0 without upgrading the rim, hub, fork and frame?
wala pakong nakikitang 650+ though me mga 29x3 nakong nakikita (maxxis chronicle).
what rims are you using? ideally + tires should be paired with i30 rims or better wider.
a 27.5 frame/fork cannot fit a 27.5+ tire since it's diameter is just a tad lower than a true 29 wheelset. in other words only 29er forks can fit a 27.5+ but not all, ie pike can take an i45 2.8, while other forks can't. as for frame most cannot. you have to measure or fit in actual.
