I am using Toyo T1R as well, running 235/35/19 on front and 255/30/19 on rears, using BMW Performance 19" Rims. All four tyres lasted me about 28,000km from 1st day i took the car. I just changed another new set last week. Performance on the dry is exceptional. On wet, will definately hydroplane if you are doing more than 160 km/h over water patches. For me in the wet, i'd rather drive not more than 110 km/h as i've had my fair share of shit & spills. Its very quiet on the road, and I am driving a E90 325i, not exactly a lightweight car! Price-wise Toyo T1R definately 20-30% cheaper than Michelin PS2. Many members or forumers hv tried PS3 and they seem to prefer PS2. And of course you can't compare Pilot Sport 2 or Toyo T1R with PP (Pilot Preceda). PP is one lower rung below both PS2 and Toyo T1R. For me, tyres are an incurring cost item, they need to be replaced every 1.5 to 2 yrs, so i will use a good performance tyre but I will not need to put the best.
Cheers.
