200 tires? Dunlop Star Specs? Bridgestone RE-71R?

The Toyos I have for street use and autocross use when I don't want to wear the Hoosiers are shot. (Thanks, Pat, but they are now gone)


I don't street-drive that much, but I get it out now and then. Want to have something decent at the LOG for the drives, and planning on driving the Mount Evans scenic byway.

Since these things last good enough for my street use, I'd like some bang for the buck in autocross, also. There are a few sites hereabouts that would cut up my Hoosiers too fast.

If I go to a big-track day, I run in the Novice group and drive totally-grandma, so track wear is no big deal.

Wheels are stock LSS: 16x6.5 and 17x7.5. Size suggestions, too, please.

RE71R. Comes in "good" stock sizes, wears well, fast @ autocross. Not sure about Dunlops, as no one seems to be using them. I'm on my 2nd set of RE71Rs this season, 4 trips to Lincoln, one trip to Utah, one trip to Salina, all kinds of local events, and the first set is not dead (500mi each way to Lincoln/Utah/Salina). I love the RE71R.

Specifically, what sizes do you recommend on the LSS wheels?

205/45-16 & 245/40-17. They fit fine on stock LSS wheels, no spacers.

2nd for the RE71Rs. I use the same size listed here and they have worked very well.

I used both the Z2 SS and the RE71R on the MR2 spyder. Definitely preferred the RE71R but the star spec was quite good, especially in the cold/wet. For your use either would work but I would definitely pick the RE71R. I just ordered a set for the FS car.

My R888s are on their way out, and there were Bridgestone folks at Thunderhill this weekend touting these. They seem really popular for auto-x, does anyone run RE71Rs on road courses?

I think they're too new for any good opinions... I expect them to be similar to re-11 though

- near grip of r888, at lower temps
- greasy when pushed

but i'd love for someone who regularly participates in track days to do a review!

I run NT01 regularly, they are the primary street tire and time trials tire for my Exige. I like the RE71 so much I won't be buying any more NT01s. I haven't done track day sessions but after enough back to back autox runs in them, I'm sure they'll do fine on a light car like ours.

tire rack test is great for an idea of auto-x performance, but their tests don't generate the same kind of heat in a tire that running around a track would.

I notice in the TR tests they mention that the re-71r is not to be stored in below freezing temps.

The storage issue is common. A048s and others have this restriction.

I spoke to a tech at Yokohama and she said they weren't kidding. Something about polymers unraveling or ~.

Had to drag my tires into the basement. Less fun than it sounds.


Edit: Usually, it's 18 or so degrees.

NT01 say don't drive on them below something like 40F. I've autoxed them in 28F and they worked great so I'm not sure how those type of disclaimers really work.

Two different issues here.

Storage: Many of these tires cannot be stored at below freezing temps. Check with mfgr.

Grip: I experimented with the RE11s to see how far into cold weather they'd still work.

Bad idea. Below about 45 F they were very slippery. Only after a highway run (which heats up tires well) did they work decently.

That day, I put my all-seasons on.

So NT01, R888, RA1 all have the same rules, its actually like 18*F. I care because where I am the car will spend the better part of a month (at least) under 18*F and I need a set of tires I can leave on the car in those conditions.

You're right, no long straights to cool the tire off.

I've read a couple of reports of people using RE71Rs for enduros with good results; they've got a different FEEL when the whole carcass is hot, but it is consistent.

They're cheap enough and wear fast enough that I'd not hesitate to try them. I've got a lot of autocross runs on them, they do change when hot, and for Solo, not for the better. Trackwise, I've only got about 30 8/10 laps at High Plains Raceway in CO, and they were absolutely fine.

If I were going to do a track day, I'd bring my RE71Rs, no question. Enduro? Sure, no problem. Actual _race_? Nope, unless that's what my competitors had to use, too. There are likely better "track" tires, but if it is not a race, and for fun, these'll be fantastic.

I'm curious to see how the v720 performs... and they will likely be my next purchase after Solo Nats. From what I've heard, they are on par with the RE-71R and Rival S. The price makes them attractive assuming they hold up comparably to abuse.
