With more and more tire manufacturers making tires 200 UTQG and below I was looking for a good set for a few AutoX events and Street Tire class Time Attacks. I looked at everything from Azenis to Toyo's R1R to only finally order a set of Potenza RE-11 that I'm currently waiting on to arrive.

What are your experiences with these new tires from Bridgestone?

thier good, and good,,, and fast,,, nothing bad about them... they wear just as good as teh old re01r!

So the RE-11 has now been released and there has been lots of buzz about its arrival we are very excited to report our findings here. We will be covering it in separate parts to be able to present data in an organized fashion and also as an archive for people to utilize when trying to choose their future tire.

Our first highlight will be of tire wear, here is the data.

Overall our experience with both the 205 and 195 have been very good. Definitely better then the re01-R's but we shall add more on that later

I will deal with the issues of wear in this post.

Lets start with some car data.

1991 Power Honda Performance Civic

Driver: Jon

Weight = 2050 lbs

Front Camber = 3.2* Rear Camber = 2.25*
Pressures used: 42F - 38R

Here are our 195 RE-11 with 49 runs on them with them mostly on an abrasive asphalt surface with majority of the courses being 40 sec and some being as long as 70sec. Tires started at 5/32 and after 50ish runs they are 4/32-3/32 tread depth and still feeling great!!!



Here are our 205 RE-11 with 20 runs on them from just the past weekend again on an abrasive asphalt surface with the course being between 85-90 seconds over 2 days. Tires also started at 5/32 and are still looking at 5/32 or just a bit less.



Height differences between the RE-11 195/50/15 and the 205/50/15.


Documented Diameters of the tires:

195/50/15 = 22.7"
205/50/15 = 23.1"
Difference = 0.400

Measured Diameters of tires:
195/50/15 (shaved 5/32, with 49 runs) = 22.250
205/50/15 (shaved 5/32, with 20 runs) = 22.625
Difference = 0.375



Speeds charted against RPM with measured diameter:
Summary: Along the RPM range there is an average of 1 mph difference between the 2 tires

When comparing corner exit there is definitely a difference one can feel on acceleration, course dependent decision will be had to made to maximize use of tires diameter.

Note: Documented R1R Diameters
195/50/15 = 22.8
205/50/15 = 23.0
225/45/15 = 23.0

^^ great info

Scracho

Awesome Info!!!

get RIGHT

Great info from oinojo.


I recently got some track time on Re-11s and I was very impressed with them for a street tire. Compared to Azenis, they did not fall off or get greasy after 15mins into a session. The grip level was excellent. The tires gave great driver feedback, it was very easy to tell when they where at their limits and inspired confidence in them. The tire wear seemed very good as well. After 4 sessions on them they hardly showed any wear at all. I was very impressed overall with them.

Here they where in action.

Very Cool looking Argh!... I want to get one so bad.

Great tire info above to thank you

get RIGHT

Thanks, you really should get one while you can. The good ones are going fast.

I have been debating getting these tires for a spirited driving and occasional track use, but with the treadwear rating lower than 200 I am concerned about tread life. Has anyone had any experience in a daily driving situation on these tires?

MSchu

weekend warrior is probably okay... daily grinder, I wouldn't do it without a big bank account

NirVTEC

My friend is using them in his STS campaign....and he wins. They were .3-.4 faster than the Hankook RS2 on a ~60sec course. Same car, same driver.
Great buy!

Wacked2882

Then he's doing something wrong. The RE-11 should be about 1.5-2sec quicker than the old RS-2 that wasn't even close to the RE-01R. The RE-11 has shown to be .4-.5 faster on a 40-45sec course than the RE-01R.

Several of the EF civics I'm racing against in ST are using the re-11's and I'm still on the re-01r's, but I'm still right behind them in time. The fastest civic is using the R1R's, but it is a national built EF.

Wacked2882

Actually almost all the EF Civic's and CRX's in the ATL region are National level cars. You aren't doing half bad being in the wrong car on the wrong tire looking at the results from this year. Hard to tell weather conditions from results though

I wouldn't be too worried about that. Remember, treadwear ratings are not comparable between brands. The treadwear rating is 180. Compare that with the 140 rating on the Bridgestone Potenza RE010 tires (stock tire for the ITR), which people claimed would last 15-20K miles and mine did over 30K.

I think you're putting too much faith in the 200 treadwear rating of the Falken Azenis RT-615, which typically lasts 10-12K miles. I think that rating is bogus, perhaps set by Falken specifically to allow it to qualify for certain competition series which require at least a 200 rating. Compared with typical treadlife for most tires from other brands, the treadwear of the RT-615 ought to be labeled 100 or less.

CivicSiRacer

I was going to say the same thing. I think my Azenis were 1 second faster than the RS-2s. I couldn't stand those tires.

CivicSiRacer

I would have to disagree and I had a mileage book to prove it. I didn't have money to spend on tires like some other ST competitors but I ran on my one set of Azenis 615s from spring (about March) til about November on my 00 Civic Si and also put on about 10,000 daily driving miles with 35 events that year (I think it was 2004 or 2005). The tread depth was around 4mm when I sold them in December of that same year.

Maybe it was the way I was rotating them every other event, or maybe I was just a smooth driver

nsxtasy

You're welcome to disagree. However, here are facts:

1. About 75 percent of the many people I know using the Azenis get 10-12K miles from them, with the rest split between those under that range and those over that range.

2. Similarly, most people I know with other tires in the 140 treadwear range (e.g. Bridgestone RE010) get 15-20K miles from them.

3. And also similarly, most folks I know with other tires in the 280-320 treadwear range - such as the Yokohama ES100 and S.drive - get 30-40K miles from them.

Compare those numbers and you'll see that if the Azenis were rated using the same scale as those Bridgestone and Yokohama tires, the treadwear rating ought to be 100 or less.

It's possible your experience is different (just as I myself have gotten 30K miles from my RE010 even though 15-20K seems to be more typical), but those are the many examples which support the above statement.

I've got a DC2-ITR and I've had four sets of RE010s since I bought the car brand new in 2001. Here is what I managed to get out of each set in kilometres. 1st set: 30,000km (mainly country driving)
2nd set: 25,000km (half country / half city driving)
3rd set: 21,000km (all city driving)
4th set: 22,000km (all city driving)

The country driving involved a lot of constant speed driving whereas the city driving involved lots of acceleration and braking which is harder on tyres.

I've just bought a set of RE-11s in the 195/55/R15 size and will have them put on the car in the next couple of weeks. I'm looking forward to getting that go-kart feel to the car back that I had when I had the RE010s on - but lost when I put on a set of RE001 Adrenalins because I couldn't source the RE010s any longer. The Adrenalins have lasted 30,000km which is great, but I've not been happy with their grip or stability during spirited driving, especially when accelerating and braking.

NH-O

Tread Wear Ratings are unreliable - even within the same manufacturer. I've just finished off my set of RE-11 tires and only got 10,500 miles out of them. I got 13,750 miles out of my last set of RE010 tires. Based on this result - the RE-11 tires are on a par with the Falken RT-615.

scottdh20

this is a 5 year old thread...why are you talking

chiprez

^^Lol^^

Btw. I out 10k miles on my set of 195's and 7 AutoX events with 15+ runs per event. Tires looked to have 6/32's when I sold off my car. I rotated and re-aligned my car every event/oil change.

Have a set of 205' re11A's sitting in my basement waiting to be abused.
