Bridgestone Potenza RE-71R

I think this tire deserves it's own thread. Let's hear about your experiences with the RE-71R!

So I'm heading to COTA soon and want to pick up some fresh tires for the weekend. My original plan was to wait for the sale and purchase NT01's in 275/35R18 square on my staggered APEX EC-7 setup:
18x10" et25 front, 18x10.5" et27 rear.

What I've been hearing though is that the RE-71R might be worth trying. I've read that they are actually good in the wet when new, stickier than the NT-01's when in their prime, and generally regarded as the new hot tire to have. The downside, and I think this especially rings true for heavier cars like ours, is that they will not last as many heat cycles as the NT-01 which is known to be good to the cords. This is just my summation from reading reviews so please feel free to share your actual experience.

I am also trying to decide whether to go 275/35R18 square or staggered with 265/35R18 fronts and 285/30R18 rears. Thoughts appreciated!

The RE71R is good to the cords.

It may or may not last as long on track as a harder compound R-compound, I have no idea there.

I would run square 285/30-18

Great tire. Cheater tire versus its tread wear rating. Great for rain. It is not going to grip like a Nitto in the dry.

I've got sets of both on narrower wheels than you 9F/10R due to class restrictions. My feeling is that for courses with more diggy corners, the 265/285 rocks and gives you a slightly lower COG but will sacrifice some sidewall compliance as it is a short tire. The 275's are more compliant and would be fine assuming you are in the heart of the power band. I have not test fit a 285 up front yet and that will be a consideration in the off season as it would further lower the COG front/rear.

Nice and I hadn't considered 285 square, good call.

Cool that you have actually tried both, thanks for the insight.

I'm going to swapping wheels and doing my rear brakes this evening or tomorrow evening. I'll test fit the 285's up front and give you some feedback on clearance.

I will try square 285s on my next set of tires with the 10.5 wheels I'm running

I'm pretty sure it fits. The 275s fit with plenty of room

Thank you both! I am still on the OEM ZCP suspension with -2.3 camber up front if that might help with any fitment advice.

I have tried 275 Nitto/RA1 variety and the RE71R. Firstly, these are modern day tires. Meaning grip is incredible, they are closer to Hoosier (don't howl as much) and are a peakier than Nitto.

Secondly, they are significantly faster in the dry and don't let anyone tell you otherwise. On a stock F80 with Pagid yellow, eibach springs and just these tires, my first time around (second lap in traffic) it did a 2:06 at VIR.

My E90 on RA1 is good for 1:24 (low) at Summit Point (when it was stock with just camber plates). This spring in an E46 with camber plates and just these tires, we did the same (for reference a One Lap M3 on MPS did a best of 1:26 completely stock).

I love them. Decent grip in the rain, although I wont say they are rain tires. For us, it gripped all the way till the cords.

Richbot is right, go for 285/18s. That's would I would put (I am running Bilstein/Eibach spring combo and surprisingly was able to fit my rear 295/30/18 with et25 10 inch wheel in the FRONT without spacer and no rubbing). Unsure about the stock strut but I like the stiffer, shorter 285 tire.

One of my students had his RE71 replaced (pro rated) under warranty from COSTCO!! Unreal.

This is my goto R comp now. A dozen of my track buddys are not running it and are significantly quicker (like a second at a minimum at Summit Point, more at VIR, Glen) with these tires.

I like the nt01 and I like a square setup on the m3, personally. Everyone will have their own preferences on tires based on driving style, experience, etc. so take this with a grain of salt.

With that level of camber, you are going to be very hard on the outside edge of the tire. I would consider running more, if you can. Both the nt01 and re71r have stiff(er) sidewalls but very soft compound on the shoulder. I'd be worried about cording the outside edge WAY faster than the rest of the tire with anything less than -3-3.5.

I would go with whichever tire you can get cheaper, cannot go wrong with either.

I have also put 295/30-18 Hoosiers on the front of these cars. Tire height is everything; there's tons of width room under those big front flares, there just aren't many wide tires that are also 25" tall

Best tires I've ever owned. Super grippy. I used these for 2 auto-x events and right off the bat shaved 3-4 seconds off my times from regular street tires. I'm not the best driver in the world but that's pretty impressive. This is the most popular tire at auto-x events currently. Cant speak on them at the track as I haven't had track day experience with them yet. I run 255 up front and 275 rear on stock 219's rims. Next set I will try to run 275 square if I could get a hold of another set of 9.5 219's for the front

Anyone compared the RE-71R to the G-Force Rival S?

With oem zcp suspension + camber plates?

That's a LOT of tire! How wide are your wheels?

Take my observations for a grain of salt. If you don't have camber up front, you will hate the Rival S. If you are running on asphalt, you will hate the Rival S. Frankly, Vorshlag sells camber plates which are allowed in CAM classes, and if your car can get camber, and fit 315's or 335's (CAM allows flares) then Rival S 18's seizes may be your droid but if you are limited to fitting no more than 305's or 285's, or have limited camber (less than - 2.5), then RE71's may be the better fit.

All of these impressions are now outdated on the Rival S -- BFG has a new compound Rival S in production now that is going to be available this fall, so time to recalibrate everything once again.

Given the Rival S is being redesigned in a new compound and released imminently, any reviews or tests you find are now outdated. It's going to be interesting to see what has changed. I think the 275/35-18 new compound tire might be available at TireRack now or soon -- need to check with them on it.

That's not true. The redesign only applies to sizes 245 and smaller and does not apply to the larger sizes. It is not a new compound, it is a new tire design. I'll find links on the discussion and cross post. Terry's article was not dealing with the new Rival S release tires which were specifically declared illegal for the 2016 Nat's. From what I understand, the "new" version will have different part #'s from the older version but the larger size part #'s are unchanged while the smaller sizes were changed along with their speed rating.

Found it -- this is the link to Andy Hollis' article with Grassroots Motorsports. He was given an advance release set to compare to other tires for a test which was just put out. https://grassrootsmotorsports.com/ar...s-2016-part-2/

Oh, interesting then. I can't believe TireRack told me the wrong information. They specifically said that "sometime after Nationals" the new compound 275/35-18 would be available. I guess the guy was totally wrong? Easy enough to find out though.

Chris Harvey of Tirerack (posts under CAH in the Paddock on http://www.roadraceautox.com/forumdi...?2-The-Paddock ) confirmed the statements made by Hollis. Essentially, this left all the guys on smaller sizes waiting for the new tire until it was excluded in Fast Track and later repeated on Solomatters. The larger sizes will probably have a higher speed rating but their compound and design is supposed to be unchanged. As for the observations of Fair, he conveniently left out the results in SS which was won by a guy on BS and only one BFG driver out of the 1st 10 and AS where John Laughlin (Rexplegi here) was 2nd behind the alien, Daddio, in his current ride, a C5Z06, when most of the class had made the same conclusion that Fair did re: wider BFG's are better. He clearly cherry picked his results to use to make a point.
