I have Kosie K1 TS rims which are 15x7. I have run both the 205/50/15 XS and 225/24/15 RS3. On my bone stock 92 the RS3 definitely rubs when going over speed bumps and hard turns. Grip wise the RS3 are better then the XS. I never had real trouble in the rain with either tire. For my DD though I would probably go with the XS just because of cost and availability.

Mehh... 225 too wide for my DD on 7" rims on stock springs. I've put my 225/50 RA1s on and got nasty fender well rub on heavy braking/cornering. Now I know why I never saw them in the size I need. Got the Stars from TR.
Err - the more I think, I'm gonna swap the order on the stars for the RS3s and make them fit... even if it means scavenging my 500/300 GC setup on the track car. I need Xidas for the track car anyway... the RS3s cheaper too!

I'm still trying to determine whether the suggestion to run the v710 on the street is a serious one...
This is probably not an ideal choice. While rain is infrequent here, it does happen from time to time. Beyond this, of course, there's always the small matter of what kind of image "racing slicks" (in layman's terms) present to your average law enforcement officer as he approaches your vehicle from the rear. "Why, no officer, I never race on the street."
I've still got at least a few months left on the RE-01Rs, and they're actually getting to be quite fun as they wear down, so I'll probably continue running 'em until the tread goes away completely. But this is a very informative thread- I'm leaning heavily in the direction of the R1R at the moment, though I'd really like to find some heard evidence describing the pixie-dust phenomenon...

Basically all we need to know is that the 195 toyo is the choice of every ST/S national champion for several years running, those guys test everything and nothing has topped the 195 R1R yet. It's made of ground up unicorn horns. unlike the other street tires they will take extreme slip angles and still grip great, but this also makes overdriving them very easy and most people find their wear rates are very bad because they are grating the rubber off the tread like mozzarella. R1R's will last a little longer if you are able to manage the slip angles at the autox, and won't have crazy fast wear they have a reputation for under normal daily driving. One thing it took me a long time to learn is that street tires hate to be stuffed onto a narrow wheel, basically look at your wheel width and choose a street tire that has the same treadwidth and it'll perform better than trying to stuff a wide tire on a narrow wheel, i.e 225 RS3 on a 7.5" wheel can be physically mounted and I have done it, but its really wants a 9" wide wheel to work optimally.
P.S. My argument against running R-Comps on the street is they are much more physically adhesive that street tires and way more likely to puncture do to picking up screws/nails that stick to the rubber and rolls around in orientation on the rubber till they puncture rather than being spit out like street tires which aren't really all that "tacky" compared to the good stuff.

Sclippy, thanks for the link- that's some good objective analysis.
Seems a shame the RS3 isn't available in a more useful size, and given that, the R1R certainly appears to be a clear winner.

It is. I have a set of 195 r1r's on 7's full tread for rain and have shaved 195 r1r's on 7.5 6uls (whenever the current shippment gets here) coming. EVERY STS car runs these tires. They feel like fail when they are awesome, RS3's feel like awesome when they are awesome.

The rule of thumb for the R1R's is to get the pressures low enough that they car feels like it's slow, basically soft. This is when the tire is fastest. The tire has a relief inside the tire that will accordion the outside of the tire so that inside can move with the road instead of slipping the tread.
Advanced Autocross-Inspired Casing With Modified Radial Construction
Improves steering response and handling by optimizing the contact patch shape.
This makes the car feel like its wobbly and soft and stuff but you are actually utilizing all the grip from the contact patch as its deforming to keep the contact patch on the road instead of slipping. Hence it feels like fail but is actually win.
So setting these tires to 30 psi or lower is their sweet spot…if you pump them up to say 40 psi then the special ‘action’ can’t work as there is too much air pressure in the tire and it cannot collapse like it needs to.

I have 205 Star Specs on 15x8 for DD and 225 NT-01 on 15x9 for everything else.
Going from Star Specs to NT-01 is a "holy sheet what happened". They are insanely loud and I can't spin them at 10psi.
I'm super happy with this setup. I ran just one set of wheels last year (225 RS-3 on 15x9) and when I wore them out the car was DONE. That was my biggest gripe with RS-3s - availability. For DD tire I want to be able to order them at will, any time of the year.
Star specs are sticky but no where near R-comp sticky.

Again, this is a street car, not a race car. I run my RE-01Rs at about 28-30 PSI cold, which works well for them and is also pretty close to what Hollis describes as the R1R's sweet spot. So I've no quarrel running tire pressures which might seem relatively low to the AutoX crowd.

Gotcha, and makes sense.

It was because I did it and loved it. But I'm not a terribly serious person. I never had any questions from LEOs, but I'm not in Commifornia so take it with a grain of salt. They are DOT legal and have all of the proper stamping to prove it.

Perez, Running the toyo R1R's since last summer. I live in the PNW so it's there's no way in hell i'm rocking my 15x9 6UL's between November and March, where it goes below freezing frequently enough, I throw on my blizzaks for those few months.
Rain wise, which we get a ton of, the R1R's are fantastic. I can vouch for MicaCeli's comments, the tires on the track feel like fail (compared to the NT01) but grip-grip-grip, especially when brand new on the track. I feel like they're overkill for the street and for a sole DD, I would get yokohama s-drives or something on not-as-wide wheels for better value/fuel economy. You'll never really 'push' the R1R's or RS3's to their limit very often on the street -- safely. Also for a daily, these sticky street tires tend to pick up a lot of rocks and kick them up in your fender wells, whether that's a pro or con, you decide.
