Calling all highway and straight line truckers! Today we’re helping you choose the right tyre for long-distance transportation. Yes, as you know, each type of road has its own tool and its own size of tyre! To find out more, we went to meet Jean-Matthieu Bodin, product category manager at Michelin, who told us about the 315/70 R 22.5, the new special long-distance standard!

Long haul tyres 315/80 make more kilometers than 315/70
Field data shows the opposite, MICHELIN X® LINE™ ENERGY™ 315/70 makes +11% in tread life vs. 315/80.
Trucks equipped with 315/70 can pull a 385/65 trailer
All recent trucks allow both plate height 55 series and 65 series.
315/80R22.5 is not an efficient tyre size and will disappear
315/80R22.5 remains very efficient for regional usage. The proof is that Michelin is launching a new 315/80R22.5 X® Multi™ Energy™
Managing two tyre sizes in my workshop has a higher cost than the benefits we can get from the performance
The benefits to switch to 315/70 R 22.5 are much higher due to the savings on fuel and cost per kilometer.
Trucks equipped with 315/70 R 22.5 generate more damages
The difference of ground clearance between 315/70 and 315/80 is 3 cms. It can be easily compensated with the air dump setting. Modern roads and adapted loading infrastructures are everywhere nowadays.
Loading docks are made for trucks in 315/80R22.5
More and more, docks are updated and adapted to 315/70 R 22.5 tyres. The trucks using 60 Series don’t seem to present any kind of issues either.
Load capacity is the same on the drive axle
The load capacity is exactly the same in dual mounting 150L, only the load index in single mount is different on drive tyres.
Tyres in 315/70R22.5 and 385/55R22.5 are more expensive than 315/80R22.5 and 385/65R22.5
On the tyre replacement market, there are no price differences between Michelin 315/70R22.5 and 315/80R22.5. Michelin price’s recommendations to the dealer are the same for both sizes.
Also, when purchasing a new truck , there is usually no price gap between tyre sizes specifications. It can still remain a gap depending on the OEM’s though.
