I have had many tyre brands over the years, and can honestly say the Toyo's have been the best I have had, especially for the money.. the Bridgestones were £130, Toyo's £75... and the performance is very similar... with maybe the edge going to Toyo.
The older T1-S have been superb in the wet and dry.. and are pretty quiet... they don't squeal when over cooking it on corners, unlike the Pirelli's I had, which complained on the lightest of bends.
The only downside is that I was getting about 8K miles on the front (FWD) I would expect much more on a RWD car.
The late T1-Rs are a bit better in the grip department, and also a quiet tyre.. I had done 10K miles, and still had plenty left, so they certainly do last longer as well.
Out of the 2, I think the older T1-S do look better, with the V tread going all the way to the edge.
When the Dunlops wear down on the GS, I will more than likely be replacing with Toyo's.. as I can't fault them one bit.
