Pneus toutes saisons...

Message par fastmike le Mar 29 Déc 2015 - 10:58

D'après Tadge, ingénieur en chef chez GM du programme Corvette, Michelin proposerait des pneus toutes saisons pour les C7 Stingray fin 2016 pour les C6 Gd Sport et C6 Z06... rien encore pour les C7 Z06 ("à l'étude...")

Tadge answered:
As we, our competitors, and tire manufacturers push the edge of the envelope on performance tires, the focus on dry traction tends to compromise traction in wet, muddy, cold and snowy conditions. Although we validate the corrosion, durability and performance of the Corvette in all weather, most customers are extremely reluctant to expose their cars to bad conditions. I've seen the majority of cars at a show disappear with just a prediction for rain. Some customers even rented local garages to keep their babies dry through a storm! Although one would assume we have some influence over the aftermarket offerings of our tire suppliers, we wouldn't be very good business partners if we forced companies into money-losing businesses. It is very expensive to put a new tire into production. The tooling costs are quite high (with unique tools for front and rear on Corvette due to our staggered sizes) and then there are design, development, and distribution costs. Since Corvette has tire sizes not shared by many other vehicles, our customers tend to be the sole source of business to pay back the cost of developing the tire. Our history is not good here. Years ago we encouraged Goodyear to make winter tires available in C5 sizes. Goodyear did just that and the only customers who bought the tires were our own GM development engineers who wanted to keep their Corvettes on the road through the Fall and Winter. Needless to say, with just a handful of sales, that was not a good business for them.

Although this sounds pessimistic, all is not lost. We are still very motivated to enable customers to use their cars for more of the year and have had quite a bit of feedback along the lines of this question. As the original equipment tires become more performance-focused, the argument for a good all-weather tire alternative becomes stronger. Michelin has been an excellent partner and already offers All-Season tires in Stingray sizes (Pilot Sport All-Season ZP's for the standard suspension and non-ZP's for Z51). We have further agreed with Michelin leadership for the additional offering of All-Season ZPs in C6 Grand Sport and Z06 sizes, in addition to the C7 Z51 sizes. The development of those tires is underway and the current plan is to have them available next year (third quarter at the latest). That leaves the C6 ZR1 and C7 Z06 uncommitted at this point. Michelin is currently studying adding those to the A/S portfolio as well.

De rien yannick! Je me doute que beaucoup suivent aussi les forums US mais au cas ou cela échappe à certains je préfère faire circuler l'info...

Bonne soirée
