I just replaced the rear tyres on my DS as they were dated 2006 and one was flat at the bottom. I couldn’t get the Retro asymmetric tyres so I decided to give Blockley a go. They arrived the next day, with tubes and rim tape and the fitter had no complaints. They’re only on the back but they drive fine.
I’m not sure they would look right on a Traction. But I’m sure they work well.
