Re: Michelin XAS in the US...
Posted: 05 Oct 2007, 17:18
some things I should know, I don't. I'm going to write these things on a piece of paper & file them in a place that is easily accessed.
Because I can't, at this time, go in my garage to check what tires my Fulvia has; so I can't report what rubber is currently meeting the road, nor the wheel size; brand (original option wheels, I have been told).
As soon as it is returned (I hope not before spring = free winter parking) or I visit the lancia-fiat-showroom where it is now parked, I will look at tire brand / dimensions / wheels it has on it &also what tires/ after- market wheels I have somewhere in the warehaus in storage, for eventual winter use.
I wasn't involved in choosing the tires; that decision was made by Giancarlo Ceccalaro (GC), a Alfa (Montreal era)/ Fiat (131 era) / Lancia (Beta era) trained Meister-Mechanic.
The woodenized tires, that did little more than keep the wheels off the ground when I bought the car ,in 2005, were from mid 90's & had not rolled, other than around the Museum where it lived (or perhaps not even rolled), since a early 90's restoration. They had great depth, but appeared rather porous.
Neither GC nor I wanted to drive on these tires (steering-system was a disaster to boot), so the wheels/tires went to GC's shop for new tires. I remember him excitedly phoning to tell me what great tires he found, "the right size $ great looks". I believed him...but perhaps today I'd be of another opinion.
That having been said, I am thrilled & satisfied...but I have no base line to compare to.
I do remember having Michelin XAS on my Peugeot 404 Automatic in early 70's.
I also remember was, no matter how I tried, in slaloms & other mickey-mouse events, I couldn't get the car sideways. I was quite pleased to beat (most) other cars -Falcon, Valiants, 1602, 6cyl Pony cars- "in my class"...which (I admit) had more to do with car/tires/brakes than the driver.
PS: Also, I didn't have to shift...so i couldn't pick the wrong gear.
More soon !
