Re: Do 20" Rims Have Many Flat Tires Due to Road Hazards-Pot Holes, Etc?
I assume that the OP is concerned with potential effects due to the shorter sidewall in 20's. I have 20's for summer tires use 18's for winter, due to concerns with potholes. Most of the 53,000 km on my car was done using the 20's, with no issues save one. I hit a sizeable chunk of metal that blew both left side tires and dented both wheels. The dealer managed to hammer out the dents and save the wheels. It is possible that 18's would have lessened or prevented the wheel damage, but who knows? It was a pretty catastrophic hit and fortunately a low probability event.
I wouldn't worry, unless you do a lot of off-roading.
