Winter
tyres on an MGBGTV8
Gordon Hesketh-Jones uses his V8 all the year round and
for touring in the UK and in Mainland Europe and it has clocked
up around 320,000 miles making a total of well over 400,000
miles on his MGBGTV8. He finds the sense of improved grip from
Winter tyres a real benefit when driving on cold wet roads.
He has two sets of V8 wheels so when the warmer weather returns
the set with Summer tyres is used again.
See our Information Gateway on replacement tyres for an MGV8.

The
prime requirement of a proper Winter tyre is that the tyre walls
in particular must remain supple etc below consistent temperatures
of 7C and such tyres will normally have deeper treads with wider
grooves than normal Summer tyres. A genuine Winter tyre will
have been tested by Government bodies and carry the "snowflake"
badge on the side-wall. It should be noted that the old "M
& S" tyres (Mud & Snow) might have even deeper/wider
grooves in the tread pattern, but in general will not pass the
7C test. For MGB V8 owners it is advisable to obtain the agreement
of |
your
insurers prior to the fitting of Winter tyres which in general
have a "T" speed rating (118mph) compared to the "H"
tyres (130mph) fitted as standard to the MGB V8GT.
My tyres are the Dutch Vredestein SnowTrac tyres which
have a strong tread pattern with deep grooves easily capable
of cutting through standing water as well as mild snow. As our
various Winter journeys were all going to involve maximum luggage
carrying, I opted for tyres with a "95" load factor
instead of the standard "88" versions. (88 version
for up to 560kg load, 95 for up to 690Kg). A useful benefit
of the Vredestein Snow Trac tyres is that they are around 1"
greater in diameter than the standard (Summer) tyres, giving
a slight increase both in chassis ride height and in the overall
gearing/fuel economy. On "Summer" tyres 5th gear in
my LT77 gearbox equates to 28.7mph, but on the Vredestein tyres
to exactly 30mph, in both cases these being calculated by maintaining
a steady 2000rpm and noting the road speed on the Sat Nav. A
set of four such Winter tyres will cost around £330 fitted,
but well worth the investment if you are planning a reasonable
amount of Winter driving and have a spare set of V8 wheels.

Snowtrac 3 declared test winner in the leading European
Winter tyre test
The Snowtrac 3 has been declared the Test Winner in the most
important Winter tyre test in Europe! Every year the German
ADAC, Switzerland's Touring Club Schweiz and the ÖAMTC
from Austria organise a major winter tyre test. These motoring
associations, equivalent to the Netherlands' ANWB, are leaders
both in their own country and abroad. The Winter tyre test which
they organise is therefore a highly prestigious event every
year. Together with 20 other Winter tyres from competitors,
the Vredestein Snowtrac 3 Winter tyre was subjected to various
tests and came out as the top performer! This result earned
the Snowtrac 3 the title Highly Recommended.

Category: Car TyresTyre Type: Tread Type: Directional. The intelligent
tread with its innovative, stepped circumferential groove enhances
the diagonal grip on wet and snowy surfaces. Tapered diagonal
grooves mean the tyre also has self-cleaning properties. Features
excellent winter performance and maximum grip on wet and dry
roads, maximum water dispersal, excellent self-cleaning of snow
and slush., low noise production in compliance with all European
regulations and superior handling. More

Gordon's information is excellent. Since we always put the winter
tyres on our cars in Germany, we take heed of the test results
published by several institutions such as the ADAC. Their tests
are very comprehensive and encompass traction in snow, wet and
dry conditions with much emphasis on braking distances at varying
temperatures. I'm not sure whether I've mentioned this in earlier
threads, but if one has any form of accident in snowy conditions
and snow tyres have not been fitted here in Germany, firstly
the insurance will not pay for your incurred damage and there
will be also a hefty fine imposed by the police.

There has been a long series of letters in Autocar about Winter
Tyres, and the majority viewpoint now is to use them all year
round which, provided you dont plan to consistently drive
at over 117mph, scrape the door-handles on the road or try too
many four-wheel drifts on tarmac, is perfectly safe. The rubber
compound is slightly softer than conventional Summer tyres so
there should be greater all-round grip but also faster
tyre wear and possibly, with the deeper tread greater tyre noise
(not that you tend to hear the tyre noise in an MG V8 of any
type!) The great cost saving in running Winter tyres all year
round of course is that it avoids the cost of buying and storing
an additional set of tyres and wheels although at around £330
for a set of 4 Vredestein Snow-Tracs our tyres are cheap compared
to the £421 for just one rear tyre for an Alpina BMW D5!
Another interesting alternative is to use the new family of
ALL-WEATHER tyres such as the Vredestein Quatrac 3 or the Hankook
OPTIMO K715 these are said to cope with 7C etc although
several internet pages praise the all-season grip but complain
of high tyre wear. 130120
Peter Garton in Germany
Your are quite correct, Gordon, in that the compound used in
the winter tyre is softer and excessive wear will be incurred
if one uses them all year round. In addition the noise is a
serious issue actually. When they wear down, they can become
a nuisance regarding that noise. Another aspect is the tread
depth which should and I repeat "should" have a minimum
depth of 3-4 millimeters to cope with snow conditions. If you
use them during the summer this aspect is lost and potentially
quite a negative when you get stuck in deeper snow somewhere.
The other point I would like to mention is that socalled "all
weather" tyres are not really suitable for snow and ice.
They cannot function favourably compared with a genuine winter
tyre (with that snowflake on the wall). I would add that if
one lives in an area in the Uk with little or no snow, they
could be a suitable alternative of course. 130120

I have used winter tyres every year since 1997. Up until 2006
or so I used Vredestein and found them to be excellent. Then
I was unable to find any and instead bought Continental winter
tyres. I have stayed with these since. They are 185/65/14 on
a Peugeot diesel. These are also excellent. The main reason
I buy them is for their vastly superior performance on Motorways
in the rain, especially if there is standing water. At 70 mph
there is no aquaplaning. In snow and ice and cold conditions
they are also vastly superior to ordinary tyres. Braking and
handling and traction are so much better. I found the 14"
Continental winter tyre to wear perhaps 10% more than the standard
Continental, and the winter tyre was actually quieter than the
standard one. Fuel consumption is roughly the same.
As has
been stated before on this wesite one MUST fit winter tyres
to all four wheels. Do not be tempted to fit only two. The winter
tyres have so much more grip that if only two winter tyres are
fitted the car will be skidding all over the place. It is safer
to fit zero winter tyres than it is to fit two. Most of the
winter tyres are uni directional only. So it is best to carry
Holts tyre repair mousse or similar in case one picks up a puncture.
With
regard to the tyre tests carried out it should be realised that
the results are for a particular size of tyre on a particular
car only. The results may vary if the 'winning' tyre is fitted
to a different size wheel on a different car.
I have had three different makes of winter tyres, the third
being Michelin winter tyres fitted to the MGB. All have been
excellent. I also run a Land Rover Discovery, used mainly for
towing duties and for farm/forestry roads, on standard 4x4 tyres.
If it is snowing or icy I will always take the Peugeot with
winter tyres as although the front wheel drive traction is not
quite as good as the Discovery, the braking and handling on
winter tyres is so much better than on the Discovery with 4x4
tyres.There
is little extra expense in using winter tyres . Once one has
bought the extra set of tyres then one has two sets of tyres
that will do more or less twice the mileage. The only aditional
cost is of either having them changed in the spring or buying
an extra set of wheels. Using steel wheels during the winter
saves the expensive alloys from being corroded by the road salt.
It is probably too late now to buy winter tyres, but if the
guy in the Audi is driving quite normally up the icy hill with
a smug grin with everybody else stuck at the bottom, it is not
because he is a great driver , its the tyres.
