I still think I'll end up replacing all four but I did have a look online for the asymmetric anything, but there's nothing in the size I'd need (255/35 R18). They seem to be available in other sizes, though. I did find two on eBay but like I said - I think it's going to be all four.
Unfortuantely my size in Goodyear R/Fs isn't on there. But thanks anyway - I hadn't seen this site and they do have other R/Fs at a good price
Yep, I’ve used them several times & never had one fail.I carry an 'Airman' kit with the pump and bottle of gloop. But I'm aware of it's limitations so I remain a member of the AA or RAC: whichever gives me the best discount each year.
If you do a search for 'rats tails' on here you'll see another option. @Smartbear was a great advocate of those.
