+1the price of a new tyre is absolutely insignificant compared to what I'm worth as far as I'm concerned.
Recently I had a screw right in the middle of my tyre.
Rob Jones said he wouldn't repair it.
JHS in Keynsham said they would but I'd have to sign a disclaimer about it being only suitable for up to 75 mph.
I got a new one, but along the way I got many totally different opinions.
