Hi BenzBoy, as you'd probably realize, I don't totally agree with your sentiments concerning the criticism by some of either Continental, Michelin or, for that matter, any other brand because of their inability to afford them. I do know of someone, with plenty of money, and he fitted Pirellis to his W126 - 420SEL. He hated them, yet they did cost a lot of money. I can't comment on Continentals, but Michelins ? You'd know, there are Michelins, and then there are Michelins. Some are made in Thailand (or at least they used to be) and they were in fact a cheap tyre in the 205.65.14" size - about $110.00 each, hardly expensive, yet I was not prepared to buy them. Most manufacturers will produce economy priced tyres.
I know of one 6.9 that is shod with fairly old Michelin XWXs. I could make those tyres chirp in the twinkling of an eye lid, and in the wet on an uphill section, skating in the one spot could be made to be the order of the day..and XWXs are not cheap tyres. Perhaps age was an issue, but really if we know what our tyres are "NOT" capable of, we don't have a problem. I have been using "lowly" Nankangs for a while, and they've given no trouble. Maybe if I booted the old girl, I might get a reaction, but even carefully calculated , yet deliberate attempts to spin the Nankangs in the wet and going uphill, have failed to get the slipping I expected. The Nankangs, incidentally now made in PRC, in size 235.45.18" cost me $A135.00 each, fitted and balanced. Regards Styria
