Sounds like you're experimenting a bit on tires. Try e-bay for some inexpensive used or older tires before settling for a set. I have Sumitomo's HTRZ IIIs on mine (rear) and they are a bargain for normal driving. If you live at the limit, however, reconsider. I'm moving to G'Year Eagle F1-GS-D3s which are better but cost a lot more. Check eBay for some good deals.
