Dunlop All Seasons, which has shown excellent re-

sult from the braking distance test at snowy roads,

has similar surface properties to winter tires and in

fact, there was almost no difference from winter tires

according to the test results. On the other hand, Pirel-

li needed more braking distance as long as a car than

Dunlop. Summer tires have shown the longest bra-

king distance at the time of brake at snowy roads.

Four-season tires have fallen

behind winter tires in the trac-tion, which is the strength of

winter tires. According to the

test results, however, even

Vredestein and Pirelli which

have shown the worst score,

have no problem in driving at

snowy roads. Surely, winter

tires remain to be safer than

four-season tires for drivers

who live in mountainous regi-

ons which have much snow-

fall in winter or mountain-clim-

bing lovers.

HYDROPLANING

BRAKE

Winter tires have disadvan-

tage in braking at the wet

road surfaces. Particularly, it

is even more difficult to bra-

ke in summer weather that

external temperature re-

aches 22C. But, suprisingly,

winter tires were better than

expected according to testresults. Goodyear and Han-

kook tires have recored the

braking distance of just about

2 meters longer than summer

tires when braking at the

speed of 100km/h.

Many other decisive factors

work in the wet round track, in

addition to the material of a ti-

re. The inner structure of a

wheel, that is, a part which de-

termines the weight distributi-

on of a vehicle, should be ap-

propriate. According to the

round track test result, Dunlop,

Barum and Maxxis recorded

worse results than winter tires,

which will have negative influ-

ence on the handling test re-

sults at wet road surfaces.

Summer tires firmly kept the

top position in this category.

There is great risk of hydroplaning

to occur particularly at the much-

worn road surfaces at the time of

heavy rainfall. Summer tires are

safer than winter tires as they ha-

ve relatively wider cut sections on

the surface. It has been conclu-

ded that four-season tires of Dun-

lop and Goodyear are the safest

at the wet road surface. For thin

195 spec. tires, h owever, winter

tires and four-season tires of

Kumho have been shown as sa-

fe according to the test results.

HANDLING

Frankly speaking: Although the

test Golf had the best handling and

agility when the summer tire was

used, Vredestein, Goodyear and

Hankook tires also never got slow

or sluggish. Dunlop and Barum got

evaluated as barely satisfying ac-

cording to the test results of lap ti-

me and handling with winter tires

fitted. Maxxis got evaluated as

commonplace due to the unba-

lanced handling. Barum 50,8

There is risk of hydroplaning at

curves too if snow is melting or it

rains. Summer tires have shown

the most excellent results, satis-

fying the expectation. Kumho,

which has fallen behind this time,

first got out of the course at the

curves. Rear axis of a car ensures

stability at curves. That is why it

is desirable to use a tire which h as

the deepest cut sections as rear

tires when replacing them.

NOISE

ROLLING FRICTION

Winter tires made of smooth

rubber mixtures not only ha-

ve smoothness and also no-

ticeably lesser noise due to

the many cut sections in the

tire surface. Only Kumho So-

lus Vire won winter tires. Sum-

mer tires also had less noise.

On the other hand, a Golf

which was equipped with

tires of Vredstein and Barum

recorded the highest noise atthe noise-measuring road.Smooth four-season tires did not win summer tires made ofhard rubber mixtures at curves. Therefore, it is desirabel for

a driver who enjoys the speed and thril l not to use four-season

tires. Surely, there is no problem in u sing excellent four-season

tires for an average driver. Kumho and Dunlop tires somwhat

decrease the joy of driving as they slightly fall behind in con-

BRAKE

The test result in dry and wet road surfaces has shown that summer

tires were more excellent than winter tires and four-season tires re-

gardless of temperature. Winter tires needed more braking distance

as long as a car than summer tires at the time of full brake. Only Dun-

lop All Season recorded worse score than winter tires and Pirelli P2500

Euro of which cut section in the tire surface is noticeably less than the

others was ranked in the upper class.

COMFORT

Comfort test is based on the subjective feelings of

the tester. The test is performed at the holey and

uneven road dedicated for comfort test which has

been specially prepared. Four-season tires of Goo-dyear and Barum recorded the most excellent score

even at the uneven road, while Kumho and Maxxis

recored the worst score.

Subjective evaluation

1,0 1,1 1,2 1, 3

Tires consume fuel, wasting

a specific amount of ener-

gy as they roll. Generally

speaking, fuel consumpti-

on increases as much as

1% for each 5% increase of

rolling friction. Kumho was

also at the head of this rol-

ling friction test. It has beenshown that Dunlop SP 4 All

Seasons had 25% more of

rolling friction than Kumho,

and therefore, consumed

more amount of fuel.

It has been concluded that almost

all the four-season tires tested are

suitable for the winter road sur-

face, although each has different

strengths and weaknesses at snowy or icy winter

roads. Of course, four-season tires have fallen be-

hind of winter tires in performance. All the four-

season tires have shown excellent scores at both

wet and dry road surfaces and Goodyear and Han-

kook recorded better scores than excellent sum-

mer tires. On the other hand, cheap Chinese tires

have not shown good results. The use of excellent

four-season tires will not only decrease the cum-

bersomeness of replacing tires seasonally and al-

so guarantee the safety in winter conditions. Par-

ticularly, it is a good news to small car owners.

CON-

CLUSION

What is a winter tire?According to the regulations, only the

tires which have a snow crystal mark

on a mountain-like ground guarantee

safety at snowy roads. Besides, tires

made by manufacturers which do not

make series production or SUV tires,

even in summer tires, often have a

M+S mark which is the abbreviati-

on of Melted snow + Snow.
