I had a lex leasing van a decade or so ago & local kwikfit said to me who repaired this puncture it’s in the sidewall (I was horrified). I said well the only place I go to is here, at this point they shit up quickly.
Never went there again that was Wisbech
Privately I’ve only had good experience with STS Tyres Pro locally who are also usable on Motability. Nearest Kwikfit is 30 miles from me so no good.
