There are two types of tires for the Cadillac XT5, which are 235/65R18 and 235/55R20. The first number 235 represents the tire width of 235MM, 65 and 55 respectively indicate the aspect ratio of the tire section is 65% and 55%, that is, the section height is 65% and 55% of the width, and 18 and 20 respectively represent the rim diameter of 18 and 20 inches. The letters or symbols in the middle have special meanings: "X" means high-pressure tire; "R" and "Z" mean radial tire; "-" means low-pressure tire. The tires of the Cadillac XT5 are original Michelin brand tires. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, and ensure that the jack touches the metal part of the frame; Raise the jack until it supports the car, the jack should be under the vehicle, check and ensure that the jack is at a right angle to the ground; Remove the hub cover, loosen the nuts counterclockwise, do not completely loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts are turned instead of the tire; Turn the nuts counterclockwise until they are loose, repeat this step for all lug nuts, and completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, tighten the nuts by hand until all nuts are hidden, at this time the tire replacement is completed. In addition to the model, the tire is also marked with the following common data: Tire cord material: represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire.

I've been driving a Cadillac XT5 for several years, and the original tires are the common size 235/65 R18, from brands like Goodyear or Michelin. I remember when I first replaced the tires, I picked the wrong size because I didn’t check the manual, and it made the ride uncomfortable—luckily, I switched back to the correct ones in time. Different XT5 trims, like the 2WD version and the high-end AWD version, may have different tire sizes; some model years use larger tires like 255/60 R18 or 265/45 R20. If you're currently looking for tires, I’d suggest checking the owner’s manual directly or asking at the dealership—don’t just buy randomly online. Incorrect tire sizing can affect grip and fuel efficiency. I check my tire wear every six months to avoid issues, and maintenance isn’t too expensive.
