Been in beetles for many years, never had this problem. had some new wheels and tyres fitted, porsche cookie cutters, had 185/55/15 fitted to the front, had a valve blow out! something that i have never seen!
now the tyre people recon that the tyre pressuers were too low. now my vw training and previous tyre fitting tells me that if the car weight and size hasnt changed why should the tyre pressure? now i was running them at 20 psi and they recon it should be 30 psi?
any comments would be gratfully recieved.
