Yes, I have an SL model.Are these the SL rims?
I agree completely with you. The rubber was too hard and I was sliding when ever I was taking off after a stop in the rain. I switched to Arizonian Silver Edition (Discount Tire brand) and the ride has improved so much.... Conti's attached to them ... I love my newer tires much more. They handle a lot better in the rain and are quieter when driving.
