I have put 2 sets of 215/45/R17 tires on my 2012 Elantra Limited, and am sick of the crappy low profile tires. Ride is rough and noisy. My last set I had some General tires on and have gotten around 60k on them with only one side wall blow out hitting a pothole in a Popeye's drive thru. I have read some posts in the forum about different tire sizes that can give more rubber between the rim and road. I talked to a tire dealer, and he says he can put a 215/50/R17 on it and it will give me about 3/4 of an inch more rubber. However, I have been thinking about putting 15 inch rims on and solving the problem all together because I am not sure I will be satisfied with the extra 3/4 of an inch. If anybody has any recommendations I would appreciate.
