- the molar levels of ethylene oxide and propylene oxide units were determined by NMR.
- no additive was added to the lubricating compositions C1 to C-5 which therefore consist simply of the combination of the plasticizing agent and the silica.
- Identical tire casings were provided with compositions C1 to C-5, by applying each of these according to determined masses on a median zone of the internal face of the corresponding tire casing, zone admitting substantially for plane of symmetry the equatorial plane of the envelope. Then these envelopes were mounted on identical rims as illustrated in FIG. 2, on which identical safety supports as previously described in relation to FIGS. Were previously mounted. 1 and 2.
- the lubricants in this test are the products "Emkarox VG 217W” and “Emkarox VG 379W” used in the previous test. In these examples, no additive was added to the lubricant compositions which therefore consist simply of the combination of the plasticizing agent and the silica.
- compositions were tested on a flat run as indicated above for test No. 1 (only 60 g of lubricating composition per envelope). The results are reported in Table 2 below.
- compositions according to the invention offer the mounted assemblies an endurance clearly greater than 200 km, while the compositions C-6 of on the one hand, C-9 and C-10 on the other hand, show comparatively degraded endurance, despite the use, which must be emphasized, of an identical lubricating agent and a very similar silica content.
- the lubricant compositions according to the invention make it possible to give the mounted assemblies of the invention lubrication and therefore endurance in run-flat which are clearly improved, even for a substantially reduced amount of lubricant composition applied.
- the mounted assemblies of the invention have the advantageous preferential characteristic of comprising less than 200 g, more preferably less than 150 g of lubricating composition.
- the amount of lubricating composition even remains less than 100 g.
