Start with the exact marking on the sidewall.

205/55R16 is a common road-focused passenger-car size. The useful comparison is not simply “which brand is cheapest,” but whether the tyre carries the correct load/speed specification and matches the comfort, wet-road and everyday driving priorities of the vehicle.

215/55R17 sits between traditional passenger-car and crossover fitments. It is typically a road-use size where stability, wet grip, comfort and the correct load rating matter more than an aggressive tread appearance.

225/45R17 is a lower-profile passenger tyre size commonly chosen for vehicles that balance everyday road use with sharper steering response. Correct pressure, wheel condition and load/speed rating matter because the shorter sidewall leaves less cushioning than taller-profile tyres.

225/65R17 is a widely used crossover and SUV road-tyre size. Most applications prioritize comfort, wet-road control, mileage and stability rather than off-road tread aggression.

235/55R19 is a modern crossover/SUV size with a relatively large rim and moderate sidewall. Buyers should balance road comfort, wet grip, stability and replacement cost while staying within the vehicle’s approved specification.

245/40R18 is a wide, low-profile road tyre size. It is often selected for cars where steering response and road holding matter, but the correct load/speed rating, wet performance and wheel protection remain essential.

245/45R19 is a large-wheel road tyre size used on some passenger and crossover applications. The right tyre should preserve the vehicle’s required load capacity while balancing comfort, wet performance and stable highway behaviour.

265/60R18 is a common SUV and pickup size where buyers may have a real choice between road/H/T and A/T patterns. The best category depends on how much of the vehicle’s use is paved-road driving versus rough-road or mixed-surface work.

265/65R17 is one of the most useful SUV/pickup sizes to compare by tyre type because it is available in road/H/T and A/T patterns. Choose around road use, load, comfort and rough-surface needs rather than tread appearance alone.

265/70R16 is a popular pickup and 4x4 size with a taller sidewall than many newer SUV sizes. It is commonly available in H/T and A/T patterns, making the driving environment the main selection question.

265/70R17 is a substantial SUV/pickup tyre size suited to road, mixed-road or all-terrain patterns depending on the vehicle. Because the overall tyre is relatively tall, any alternative size should be checked carefully for clearance and gearing/speedometer effects.

275/65R18 is a large pickup/SUV size where load capability, tread type and vehicle clearance all matter. It is often considered for road/H/T or A/T use rather than passenger-car style touring tyres.

285/50R20 is a wide, large-wheel SUV tyre size. Correct load capability, strong wet-road behaviour and stable highway performance are important because these tyres support heavier vehicles on 20-inch wheels.

31x10.5R15 is a flotation-style 4x4 tyre size commonly associated with older pickups and off-road builds. It is usually considered in A/T or M/T patterns, so road manners versus off-road traction should be an explicit decision.

33x12.50R17 is a large flotation-style 4x4 tyre size normally associated with modified pickups or off-road-oriented vehicles. It should be treated as a fitment decision, not a simple cosmetic upgrade.

225/75R15C is a commercial-vehicle tyre size. The “C” construction is the key part of the specification: this is not simply a passenger tyre with the same width, profile and rim diameter.
