Grimworks is a tyre shop at 2 Yishun Industrial Street 1, #01-34, in Yishun's industrial quarter, holding a 5.0 Google rating and keeping its online presence on Facebook rather than a standalone website.
A good tyre shop earns its keep on advice as much as fitment: reading the size and speed rating off your sidewall, steering you towards wet grip that suits Singapore's sudden downpours, and telling you honestly whether a puncture can be safely repaired or the tyre is finished. Regulars know to ask for alignment and balancing whenever new rubber goes on, since misalignment quietly chews through a set in a fraction of its normal life. Tread depth matters more here than in most places, because a tyre that feels fine on dry roads can still turn vague in standing water after a heavy storm.
For drivers in and around Yishun, Grimworks puts that kind of grounded tyre knowledge within easy reach of the neighbourhood's workshops.
