I've been doing research for tires for an older Jag. I can't help you
but I can show you some of what I've found while researching tires.
For example, there are 13 different lines of "Michelin Pilot" tires.
There are charts at TireRack.com that list the tires they sell (by
the charts show ratings of tire characteristics by prior buyers. For
here is a chart of the High Performance All-Season category; the names of
the tires they carry in your size are highlighted on the chart.
Click on a tire name for more information about the tire, including pricing.
Although the tires that aren't highlighted are not available from Tire Rack
in your size, the size you need may be available from dealers. In the chart
above, however, the top-rated tire is not made in your exact size:

Here is a chart with another category of tires:

Considering your location, you may (or may not) want
to choose yet a different category of tire, since snow & ice traction
characteristics of the tires in both the above categories are not good:

They may or may not have a high speed rating, you need to
check the individual tire, in your size, to find out, since
different sizes in the same tire line often have different speed ratings.
BTW, if you only consider the charts for which I provided links,
the Continental ContiExtremeContact tire looks to be a good choice
because it's rated fairly high in all categories (or at least appears
to be a good compromise that isn't seriously deficient in any category),
including ice & snow, it's a V-rated tire in your size, and it's
less expensive than many of the others. However, it may be a little
noisy, and may not last as many miles as others.
Also realize that the ratings for different categories of tires
may not be directly comparable between categories, since
for example, drivers buying different categories of tires
have different expectations of the tire they buy, and may
weight their evaluations in light of the price they paid.
I pay particular attention to the "Would Buy Again?" column,
having made a few mistakes in the past when buying tires...
note that it doesn't always track with the average ratings
(rank within category).
And, if you go read the individual buyer comments, and sort
them to read the worst ratings first, you quickly realize
that for every tire there are buyers who absolutely hate the tire.
I drive an x300 in Germany (mucho Autobahn). My tires are:
Summer: Goodyear Excellence - 225/55
Pro: very smooth, very precise steering in small corners and high
Contra: they got a bit noisy after the first 10000 Km or so.
Winter: Michelin Pilot Alpine A2 - 225/60
Pro: perfect grip on snow, ice, and rain (where a big Jag can be quite
nasty sometimes), surprisingly quiet, smooth riding for winter tires.
Contra: whobbly steering upward of 150 Km/h, although they are rated
much higher. Probably due to the /60 form factor, I don't know...
Snow and ice are not much of a problem in Victoria either. Well, maybe 3 or
4 times in 100 years! Any good all weather radial will do. These days, any
good name brand tire is road speed rated. Just check with the tire store to
make sure the tires are rated for the maximum speed you drive at.
Speed limits here are much lower than in the past. Really cheap department
store tires are no longer sold here. Any good brand name radial will be
rated higher, way higher! The Insurance Corporation of British Columbia
(ICBC), provides basic insurance to everyone here. If you buy legal tires,
there will be insurance coverage. You will only be in trouble if the tires
are worn beyond the warning strips. A Vanden plas is not an Aston Martin,
or Ferrari, which need 200 MPH tires!
There is a little more to tyre choice than flat out speed rating; a Jag
is heavy car, which puts more strain on the tyres in general running and
cornering than you'd get with, say, a light Japanese sports car running
on similarly wide alloys.
You also have a lot of power available to put down onto the road; a
lower rated tyre may have problems when driven hard (harsh acceleration,
rapid braking) even if you never approach the theoretical maximum speed
rating. Of course, if you waft around in your car just using the "grace
and space" part of the triumvirate, then you won't need high performance
True, but a Jag is no heavier, or more powerful than a large American car,
but they do handle better. There is a good mix of small imports, and large
Canadian made vehicles in this area, and a large variety of tires available.
You do have to buy tires that are suited to the car!
