Run-flat tyres can sometimes divide opinion. Some drivers value the peace of mind that they bring: knowing that in the event of a puncture, the tyre will continue to function. While others can hesitate over cost, comfort, or weight.
With
Uniroyal, the approach is simple and practical.
Uniroyal’s Self-Supporting Run-flat (SSR) technology uses reinforced sidewalls. Tyres with SSR are capable of being used after a puncture for up to 50 miles – when traveling at a maximum of 50 mph.
It’s by no means a permanent fix, but it’s enough to get you safely to a garage or home. Rather than being stranded by the roadside.
For many, that can mean turning a stressful situation into a more manageable one.
How SSR Fits with the Uniroyal Story
Uniroyal is known as 'the rain tyre' brand.
Founded in 1868, their focus has strongly been on wet-weather grip and aquaplaning resistance. The use of their SSR technology doesn’t replace that – it adds to it.
- Wet grip first: Shark Skin Technology™ and flow-optimised tread designs channel water away.
- SSR alongside: In selected sizes, you can combine that confident wet-weather performance with the reassurance of run-flat mobility.
SSR Applications
SSR was first formalised in the RainSport 3 in 2018, when Uniroyal launched eight run-flat sizes between 16–18".
With each earning the EU “A” ratings for wet grip. Underlining how naturally SSR fits with Uniroyal’s rain performance story.
Today, the
RainSport 3 remains a good choice for drivers seeking the strongest combination of wet-weather safety with run flat capability.
The Takeaway
Uniroyal has always been about confidence in the rain. With its tyres featuring SSR, that wet grip performance gains another layer. With safe mobility even after a puncture.
For drivers who want wet-weather performance plus run-flat reassurance, the RainSport 3 with SSR is the natural choice – less drama, more control.
