Comparison Yokohama Geolandar A/T G015 225/65 R17 102H vs Toyo Open Country A/T Plus 225/65 R17 102H

The rolling resistance rating that the tyre corresponds to. The higher this figure, the lower the resistance, the less fuel is spent to overcome it and the more economical the tyre is. Efficiency indices are denoted by letters of the Latin alphabet in descending order of efficiency: A(highest efficiency), B, C, D, E, F, G(lowest efficiency).

With other things being equal, more economical tyres tend to cost more, but the difference is offset by fuel economy.

An index that determines the overall performance of a tyre on wet pavement. Lettered from A(highest) to G(lowest); intermediate options, respectively — B, C, D, E and F.

The higher this indicator, the stronger the tyre grips to the wet road, the more efficient and safer it will be in difficult weather conditions. At the same time, it is worth noting that a low grip index does not mean unsuitability for driving in rain or snow — you just need to be more careful using such tyres. Conversely, a high index does not relieve the driver of the need to be careful in difficult weather conditions.
