From 225/55R18 to 225/60R17: Taller Sidewall, Smaller Rim

Of the five models the dealer prices in both 225/55R18 and 225/60R17, three cost more in 225/60R17 and two cost less. For the same model, the 17-inch tyre is not automatically the cheaper one. These are Shaharyar Traders' prices on CircleWheels, last updated on 3 June 2026.

The two sizes are 3 mm apart in overall diameter, and moving between them changes the wheels as well as the tyres. The 225/55R18 page and the 225/60R17 page hold the full price lists for each size.

11 mm more sidewall on 225/60R17, 3 mm less overall

Section width stays at 225 mm in both sizes. Going from 225/55R18 to 225/60R17, the rim drops from 18 to 17 inches and the sidewall grows by 11 mm, from 124 mm to 135 mm. That taller sidewall nearly makes up for the smaller wheel: the overall diameter falls by 3 mm, or 0.4%.

The circumference shrinks by the same small margin, so the 17-inch tyre turns about 454 times a kilometre against about 452 for the 18-inch one. Going the other way, from 225/60R17 to 225/55R18, every one of these changes reverses: 11 mm less sidewall, a larger rim and 3 mm more overall diameter.

What the 0.4% does to the speedometer

Because 225/60R17 is 3 mm smaller across and turns about 454 times a kilometre rather than about 452, a speedometer set up for 225/55R18 would show about 0.4% more than the true speed on it. The reverse swap, 225/55R18 on a car set up for 225/60R17, leaves the reading below the true speed.

Neither direction says which size a given car should run. The door-jamb placard decides that, and it is the reference for any change. This comparison is no basis for switching sizes to save money: the diameter change shifts what the speedometer shows, whatever the price lists say.

Moving to 17-inch tyres means 17-inch wheels

225/55R18 fits an 18-inch rim and 225/60R17 a 17-inch rim, so a move in either direction means new wheels as well as new tyres. CircleWheels prices tyres only, so none of the figures below is the cost of a switch; the wheels are an extra cost that sits outside these numbers.

One car page on CircleWheels lists both sizes: the Honda HR-V (2021–2026), whose page lists 215/60/17, 225/50/18, 225/55/18 and 225/60/17. A car page gathers sizes across trims and years, so it does not show that one car takes both.

Five models priced in both sizes

The Bridgestone Alenza 001 row stands out: the 17-inch version carries Rs 17,000 a tyre more than the 18-inch one. The Yokohama and Dunlop models also cost more in 225/60R17, by smaller amounts.

The two models that cost less in 225/60R17 are both Michelins. The Pilot Sport 4 is Rs 11,500 a tyre cheaper in the 17-inch size, while the Pilot Sport 5 is only Rs 1,000 apart. The direction of the gap depends on the model, so a price seen in one size is no guide to the same model in the other.

Cheapest tyres listed with a model name in each size

In 225/55R18, two Nexen tyres share the lowest model-name price of Rs 43,500: the Nexen NFERA SU4 and the Nexen NPRIZ AH8. In 225/60R17 the lowest is the Yokohama BluEarth-ES ES32 alone, at Rs 45,000. That Rs 1,500 difference between the Rs 43,500 Nexens and the Rs 45,000 Yokohama describes those particular tyres only, not the two sizes as a whole.

Each size has 74 priced listings, 53 of them brand-only. In 225/55R18, 50 of those brand-only listings sit at exactly Rs 24,500; in 225/60R17, 51 sit at exactly Rs 26,500.

The model-name tyres in 225/55R18 come from 10 brands, against 7 in 225/60R17. Just above the Nexens, the Kumho Krugen starts the Kumho range in 225/55R18. In 225/60R17, the next brand up from Yokohama is Dunlop, starting with the Dunlop SP Sport MAXX 060 at Rs 50,000. At the top of both sizes sit Michelins: the Pilot Sport 5 and Primacy 5 at Rs 79,000 in 225/55R18, and the Pilot Sport 5 at Rs 78,000 in 225/60R17.
