So a little while ago I picked up some T1-Rs off of edgeracing.com. These are supposedly the "new and improved" version of the T1-S. I haven't tested the T1-S myself, so I can't say much about them.

I got the tires in a 245/45ZR16 size to fit my Z32 TT wheels. I only have them up front, but let's face it, the rears in our cars don't do much except lock up when we want to get naughty.

Anyway, They grip incredibly. I haven't had a chance to test them in the wet yet, but seeing as I just washed my car, I'm sure it'll rain within the next few days or so. Dry grip is very impressive. They seem to ride somewhat decently for a 45 series tire... so, not great, but slightly more bearable than the Kumho 712s. I've noticed that I can slip-launch the car from 2k with very little wheelspin (and they still pull very hard while spinning), very impressive both compared with the 245/45R16 Kumho 712s and the 215/55R16 Avons I had on there earlier. Yes, they pull very hard in these cases and the tires are also one of the lightest street tires out there by a few lbs--keep in mind that this is more important than wheel weight, since the wheel's mass is distributed over the entire wheel, while the tire's mass is only at the very outer portion of the rotating mass. I've noticed significantly less wheelhop as well, but that's more because of the aspect ratio of the tire as well as the fact that they spin significantly less.

Sidewalls seem a little soft. They're not very soft, and they keep the car pretty stable at all speeds, but when you really crank the wheel they mush just a little. In these instances, at the limit of grip, they complain more in the form of wailing, much lower pitched than the squealing I'm used to, and not nearly as loud--but they do make some noise.

Noise... is not bad. They don't hum at all, as I've heard the T1-S' did. It's more of a white "road noise" as opposed to the "tire noise" that you'd think of when your tires hum. Road noise is noticeable, but easily shrugged off. I'll have to take a few more highways trips and listen closely before I can say this for sure.

And now for some pictures, since I just took a bunch.







You might notice that the sidewall is sort of... "bubbly" instead of straight... It only took me about 30 seconds to like it. I didn't like the tread pattern at first either, but it grew on me very quickly.

Yet one more pic, because I like it. Hehe.

 

nice write up i plan on having that same setup soon

 

Wow, the tread on those looks agressive as hell! Those are sick. Nice pics btw.

 

With Z32 TT wheels and T1-Rs? Nice, I'd like to see that on another 4th gen, it's really uncommon (I mean the Z32 wheels). Definitely post up some pics when you get 'em.

Thanks man, I really like the tread as well, which is why I took so many pics of it.

 

i just ordered as set as well

 

I'm guessing you have the TT wheels (16x8.5)? And what kind of wheels do you have in the rears? Rear tire size?

 

vsamoylov, thanks for the centercaps, and they're damn good tires. You'll (hopefully) like em.

limsandy, thanks for the wheel locks, and yeah they're TT rears up front--16*8.5 and TT fronts (or just NA wheels) in the rear--16*7.5. 245/45F and 225/50R. I have Potenza RE730s in the rear, but they don't matter too much for the handling of the car.

 

center caps fit perfectly?

 

Yup, it doesn't quite look it in the pics but they fit fine.

 

I have the same centercaps that I might sell together with the set of Z32 wheels that I'm trying to sell locally.

It's interesting how you put the wider wheels and tires in the front (which should be a plus for FWD) and I wonder if you get any performance benefit, in terms of handling, over same tire widths all-around?

 

Well, technically it should reduce understeer at the limit, which it does, as I can feel the back end creep out whenever I'm taking a hard sweeper and lift. It's not too noticeable otherwise though, I just wanted the wider tires where they're used. So, I can corner better now that I have 245s up front and 225s in rear than if I had 225F/245R, but I wouldn't notice all that much if I just had 245s all around. 245F/225R should be more noticeable in, say, an autox event though.

 

wet response on these tires are great. i had nt555 (nitto's) before and i like these much better. in dry and wet.

 

Wheels and tires look really good man. I wish i could of afforded some better tires.

 

i just got my set mounted to day and will be putting them on the car tomorrow.

 

I've heard great things about these tires elsewhere too.

 

That is in fact a perfect stagger size.

 

I've had the T1-R's on for about 5 months and love them as well. I'm running 245/35/20's. Living in So Cal you don't get much rain testing but we've had quite a bit lately and I must say they handle great in wet weather. With the K-Sports and recently installed FSTB and RSB and this thing sticks to the road!!
