With top up, it is difficult to look backward to park because of the hump. Run flat tires are a very hard ride, and not suitable for winter- pothole/cracked streets. When tire hits pothole, you will need to replace tire and rim for approximately $1,000 each. I replaced three tires at a cost of $3,000 in one year.
Get rid of hump on trunk lid to improve visibility. Go with regular tires instead of run flat tires. Get tire warranty.
