I got a set of 235/40/17 Toyo T1-S's installed yesterday. For the first 30km they sucked obviously, but then they slowly and slowly started to scrub in, started to suprise me.

First off (as stupid as it may sound), two hours after installing them I was at Cayuga doing 1/4 mile runs. They gripped awesome there. Later at night I was just doing some braking test from various speeds and I could hold 1Gminimum, which I though was pretty impressive. Even from 200-0km, it was at least 1 continuous forward G until I stopped.

In the rain these tires also rule. Then again they are at full tread, but I know of more then one guy who uses the T1-S's as their rain track tires.

At the auto-x earlier today, every right hand corner was at 1G, and every left hand corner was between .9-1G (I guess I'm not as confident turning left, I blame the A-pillar). Here is a G graph taken from my G-Tech, notice the lateral g's:

good info.. thanks! I'm getting TI-S's for next summer... keep us posted on how it is when the tread wears... and tread life.

Damn my secret is out. :D

Look like I'll have to drive harder next summer. ;)

I am dying to get a set... especially with the exchange rate right now its almost CRIMINAL to not buy them from that Bimmerforums vendor.

:idea:

The new T1-Rs should prove to be even better with better wear rate and outside rain channels to improve direction without reduction in water dissipation.

Can't wait.. found Michelin Pilots Sports very skittish in the wet.

www.edgeracing.com has better prices than that njzprettyboy or something on bimmerforums.

I had these tires before, they wear out FAST. But admittedly, I could drive with confidence in the rain like no other tire.

i just switches to these tires this season. excellent in rain and dry conditions. I haven't noticed any wear since i seldom push my car, and when i do, they hook very well. overtime, i'm sure i'll be able to give you a better review.

Nope, not cheaper, I just checked. I paid $600US, shipping including. I ended up paying $910CDN, after duties and taxes.

I have used two sets on my bimmer and one set on my audi. I've switched to Kumho MX (dry) on the bimmer and Yoko Parada spec 2 on my audi. The T1-S is nice in the rain but I don't drive my car in the rain anymore. I find the Kumho to have better dry traction and it can handle side load better. I just got the Yoko, but so far, it seems pretty good. I'm probably going to run the Yoko on my bimmer next year (225/35/19's). As good as these tires are, they don't even come close to the RA-1's for track use.

That is what everyone tells me, luckily I just bought another set of wheels with RA-1's on them....I can't wait to try them at the auto-x's next season. *smoke*

The guys who are always winning the auto-x class that I'm in (3 -series, 6-cyl, modified) are on RA-1's. Hopefully I'll be one of them :P

make sure they are at 42 psi when hot. You only do auto-x? Have you been to shannoville? I find it more fun at the track. 200km/hr down the back straight, under hard, hard braking to make the right hand turn, really fun stuff.

I haven't been to Shannonville yet, hopefully next year. The only track I have driven on is Mosport, and I have been a passenger on the Mosport DDT. I don't think the T1-S's will see the track, except for maybe a driving school. I guess it would make more sense to take street tires to a driving school then r-compounds.

I've been to Shannonville, many times to ride along and to spectate. I don't have a car to drive on the track which explains why I've spectated only, but I have a relative idea of the driving lines there. From my personal perspective, Shannonville doesn't seem to be that challenging once you learn the lines or after going there several times. The track is pretty much flat (no elevation changes) unlike Mosport and there are no blind corners at all either. I'm not putting Shannonville down, it's a fun track to take your car around and learn, but I personally like the challenge of Mosport after going there this year to do some filming for the Porsche Club Race and the AMLS weekend.

Shannonville is fun and you can push hard without to much worry. A lot of open fields for mistakes. A lot of cars get totaled at Mosport. I just want to have some fun without too much worried. My last track day, a supercharged S2000 losted in front of me, I had to steer into the weeds.

Hey Nelson, I was just reading up on the upcoming T1-R's, they look promising. The same basic tread pattern, just stronger shoulders (and hopefully sidewall). A few message boards in Europe have very positive reviews. And most importantly for me, the very rare size I need for my car (think wide) that the T1-S comes in is officially in production on the T1-R line. :)

This is why everyone is selling the T1-S's so cheap, the distributors are tryingto clear them out. I'm happy:)

Guys,

Toyo T1S is a great tire (dry or wet) on par with Bridgestone S03. It has been a favourite with the BMW club (as a non-Rcompound tire) for several years because it offered the same performance of their competitors but cheaper. As the word got out (of course), their prices climbed in 2002 and 2003 again. $900 (canadian) for a set of 17" is an excellent price.

By the way, Toyo recommends a negative camber (at least "-2") for their RA1 tire. Which means you will need camber plates.
The general consensus among BMW Club members (US or Canada) is only to switch from street tires to R-Compounds when you are an intermediate level ("B") group member (I am talking about driving on big tracks like Mosport, Watkins Glen etc.) because as a beginner student (C group) there are a lot of things you can learn as a driver even on a good street tire like (T1S, S03 or Pilot Sport).

Well, I already have front camber plates, and happen to be running -2 all around. So I guess that'll work.

In regards to my next driving school, I'll just bring the two sets of wheels in case. My last driving school my instructor recommended me to move up to advanced, but that is up to the organizers to decide.
