The Buick Encore GX is the slightly larger sibling to the Encore, built on the GM VSS-F platform (shared with Chevy Trailblazer). It competes in the subcompact luxury crossover space and is marketed on quiet cabin refinement and comfort — a priority that should drive tire selection.
Buick Encore GX tire sizes
Most Encore GX trims ride on 225/55R18 — Preferred and Sport Touring come standard on 18-inch wheels, while the Avenir (and the Sport Touring's optional 19-inch package) uses 245/45R19. All trims are available in FWD or AWD.
Verify on the driver door sticker. The trim-based size differences mean a full replacement set requires knowing exactly which trim you have.

Frequently asked
What tire size does the Buick Encore GX use?
Preferred and Sport Touring: 225/55R18. Avenir and optional 19-inch packages: 245/45R19. Verify on the driver door sticker.
How much do Buick Encore GX tires cost?
225/55R18: $110 to $170 per tire. A full set of four installed runs $440 to $680.
How do I know when my Encore GX needs new tires?
Use the quarter test for the practical 4/32 warning and a penny for the legal limit. Since the Encore GX is sold on a quiet, comfortable ride, rising road noise and weaker wet grip are often the first hints the tread is going. Uneven wear is worth an alignment check.
Should I replace all four Encore GX tires at once?
On an AWD Encore GX, all four together keeps tread even and protects the system. On a front-wheel-drive one, pairs are fine; put the newer tires on the rear for wet stability. A shop can measure your tread and tell you which situation you're in.
