I'm thinking about keeping RFT's on mine when it comes time to get new tires as they seem to attract nails and screws more than non-RFT's. Since I have the warranty I would rather have a new tire than just them patching a non-RFT. I know RFTs ride rougher but it seems I would get more new tires that way ha. I have had 3 tire replacements on my warranty and I've had the car for 15 days.
