I recently bought a full set of tyres and did a fair bit of research across a number of forums and found made the following shortlist. Any of the will be excellent, and as the RA's are only 15", the difference in price is negligible:
1. Goodyear Asymetricals
2. Uniroyal Rainsports
3. Goodyear GSD3's
4. Toyo T1-R
I went for the T1-R's as they were cheapest at the time, and they didn't have the uniroyals in stock.
