About 2 weeks ago I had a set of T1R's put on my WRX. They replaced Goodyear GS-D3's.
Initially, I was very disappointed with their handling -- the steering seemed vague, and the cornering response reminded me of my Dunlop Winter Sport M3's. There was a delay between the front end reacting to steering input and the rear end following and taking a 'set' in a corner.
I checked the pressures, and although I had told both the service manager and the tech that I wanted 35 psi in front and 30 in the rear, they were all at 32 psi. I tried 35/30 psi and that helped some, but they still felt soft and 'squirmy'.
I've since bumped the pressures up to where they are now 39/33. The handling and turn-in are better but still not what I was used to.
Then I realized (and this may be obvious to many of you) -- whenever we get new tires, we can't really fairly compare them to the old ones. Because the older tires probably had very little tread left, they would of course handle better -- that's the reason some people have tires 'shaved'.
I also remembered that I was disappointed with the GS-D3's when I first had them installed -- they seemed comparatively loose and vague feeling compared to the Firestone SZ-50 EP's that they replaced. Thinking back, the Goodyear's got progressively better as they wore down -- it was only when they got close to the wear bars and started to be more prone to hydroplaning that I replaced them. If I lived in Vegas or LA I would have left them on for a while longer.
So I'm reserving final judgment on the T1R's for now. They seem to be better after only 2 weeks (about 750 miles). Hopefully, they will get 'tighter' after the tread wears down a bit. They seem relatively quiet, track straight (no tramlining) and ride fairly soft for a "max performance" summer tire. I've only driven in rain once or twice since they were installed but they seem to have almost the same amount of traction on wet pavement as they do on dry. As for hydroplaning resistance, I purposely hit low spot on I-270 where I know water collects and they sliced right through with barely a tug on the wheel -- very impressive (although the GS-D3's would have been about the same when they were new).
Anyone else have an opinion on the T1R's?
