Kumho Solus 4S HA32 Review

The Kumho Solus 4S HA32 is an all-season tyre in the mid-price segment that is characterised by a balanced price-performance ratio. In various tests, it shows a solid overall performance with particular strengths in terms of economy.

Performance on snow

The Kumho Solus 4S HA32 performs surprisingly well on wintry roads. The tread pattern enables effective traction even in difficult snow conditions. The cornering on snow impresses with good controllability and precision. Handling on snow-covered roads feels safe. Stability in bends is maintained even in deep snow. The sipes in the tread pattern ensure effective interlocking with the snow surface. The snow performance exceeds expectations for a tyre in this price range. Controllability is maintained even during sudden steering manoeuvres. Traction when starting and accelerating is good. The winter properties were positively evaluated in all reviews.

In the ADAC test 2024, the tyre achieved a good grade of 2.1 for snow handling.

The ÖAMTC test 2024 confirmed the good winter properties with a grade of 1.88 for snow handling. The braking tests on snow showed above-average values with a grade of 1.95.

Performance on wet roads

The Kumho Solus 4S HA32 performs satisfactorily on wet roads, but it does have some weaknesses. Its wet grip does not match that of its premium competitors and it is particularly weak during dynamic manoeuvres. Handling on wet roads feels unsafe, with delayed feedback. Its aquaplaning resistance is only average, which is particularly noticeable at higher speeds. Stability when changing lanes on wet roads is limited. Deceleration on wet asphalt is below average. The car requires increased attention in critical situations. Wet performance falls short of expectations. Cornering force is reduced in wet conditions. Precision when turning on wet roads leaves something to be desired.

In the ADAC test in 2024, the tyre only achieved a grade of 2.9 for wet handling.

The ÖAMTC test confirmed the weaknesses with a grade of 3.27 for wet handling.

In the Auto Bild test, the tyre showed significant weaknesses with a braking distance of 49.8 metres on a wet road surface.

Dry handling

The Kumho Solus 4S HA32 performs averagely on dry roads. The tyre's construction offers only a moderate balance between comfort and handling properties. The steering response is delayed and not very precise. The cornering forces are reduced under dynamic driving. Feedback on the road surface is limited. The tyre shows average stability when changing lanes. The braking performance on dry roads is in the lower middle range. The cornering stability is only satisfactory. The steering precision decreases at higher speeds. The driving stability requires frequent corrections.

In the ADAC test, the dry performance was rated at 3.0.

The Austrian automobile club ÖAMTC gave the handling on dry roads a grade of 3.13.

In the Auto Bild test, the braking distance on a dry road was measured at 41.4 metres.

Braking performance

The braking properties of the Kumho Solus 4S HA32 show a differentiated picture with significant differences depending on the road surface. The braking performance on a dry road is in the middle range with an average of 41.4 metres from 100 km/h. The braking distances on a wet road are clearly too long at 49.8 metres from 100 km/h. On the other hand, the braking performance on snow is convincing with good values. Stability during braking is not always optimal. The sensitivity of the braking force requires increased attention. The ABS support does not work optimally with the tyre profile. The braking force distribution shows weaknesses under different road conditions. The braking performance varies greatly depending on the temperature. The directional stability during braking is in need of improvement. The deceleration values are only satisfactory overall.

The ADAC test in 2024 gave the wet braking performance a grade of 3.2.

In the ÖAMTC test, the tyre achieved a good grade of 1.95 when braking on snow.

The braking performance on dry roads was rated as average in the Auto Bild test.

Cost-effectiveness

The Kumho Solus 4S HA32 impresses with its good cost-effectiveness in everyday use. The predicted mileage of over 45,000 kilometres puts it in a good midfield position. Tyre wear is acceptable at an average of 70 mg/km/tonne. The tyre weight has been optimised, which has a positive effect on fuel consumption. At 5.8 l/100 km, consumption is in the medium range. Durability meets expectations for a tyre in this price range. The rubber compound shows good wear resistance. Even wear ensures a reasonable service life. The environmental balance is average. The total costs per 1000 kilometres are attractive. The efficiency of the tyre is satisfactory.

In the ADAC test 2024, the tyre achieved good results for wear with a grade of 2.1.

The ÖAMTC confirmed the cost-effectiveness with a grade of 2.5. The fuel efficiency was rated 2.7 in the test.

Noise

The Kumho Solus 4S HA32 exhibits average noise behaviour in everyday driving. The tread design leads to a noticeable, but not disturbing, rolling noise. At 71.5 dB(A), the measured noise emission is in the middle range of the test field. The interior acoustics are acceptable at normal speeds. The frequency distribution of the rolling noise shows slight weaknesses at certain speeds. The noise level varies significantly depending on the road surface. The coordination of the profile elements could be more harmonious. The noise increases noticeably at higher speeds. The vibration damping is average. The acoustic performance is in line with the price range. The smoothness is satisfactory overall.

The ÖAMTC test 2024 rated the noise development with a grade of 3.0.

In the ADAC test, the rolling noise was rated as average with a grade of 3.0. The interior acoustics received a grade of 3.0 in the test.

Value for money

The Kumho Solus 4S HA32 is positioned as a cost-effective all-season tyre with an attractive price-performance ratio. The moderate mileage and average wear are acceptable in relation to the purchase price. The overall performance meets the expectations for a tyre in this price range. The durability is reasonable for the price. The materials used offer satisfactory quality. The technology is inferior to that of premium tyres, but is justified in terms of price. The total cost over the service life is attractive. The efficiency of the tyre is reasonable for the price. Price stability is good compared to other tyres in this class. The investment is worthwhile for price-conscious drivers.
