How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
26/100From 17 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.

Feedback on the Kumho PorTran 4S CX11 is mixed, based on only five reviews. Several drivers praise its grip, all-condition performance and improvement over factory tires, but the two lowest ratings describe serious tread durability problems, including cracking and disintegration.
Pros
- Good grip and solid performance in poor conditions, including on a VW Crafter
- Described as performing very well and noticeably better than factory original tires
- Decent, reasonable overall value and satisfaction from several users
- Repeat purchase: one reviewer is on their second set
Cons
- Premature tread degradation: longitudinal cracks in the tread grooves in under three years, which failed a TÜV inspection
- Reported disintegration of the tread in the middle of the tire, despite otherwise good performance
- Unresponsive customer service when a user reported the defect
- Durability concerns appear to undermine otherwise positive performance impressions
Worth knowing
- Vehicle and size data were not provided for most reviews, so size-specific conclusions cannot be drawn.
- The only vehicle mentioned is a VW Crafter (van), where the tire was reported to perform well in poor conditions.
