AD08R vs RE71?

Anyone running the AD08R on Elise/Exige?

Tire Rack doesn't seem to stock the front size, but they're available from the UK.

I finally found a set of Sport Cup wheels, considering which tires to use.

i use the AD08R on the road and track in my turbo elise and they have been great. They have about 15 minutes in them on track before they start getting overheated and slippery as hell

Uhh, so you mean you like them on the street but not on the track?

re71, just get a 205 front

I was going to use 205 fronts regardless which tires I chose.

Much of this is determined by how you use your car.

Do you mind keeping your tires above 15F?

Any track?

Drive in rain? RE-71 good with wet surfaces but NOT standing water (as per mfgr and TR).

Tool around or drive fast on twisty roads?

Get the picture?

I have plenty of experience with the general virtues and limitations of DOT track tires.

I've read plenty of opinions on the RE71, was hoping for comments from more folks with firsthand experience with the AD08R.

I believe glb was pointing out that your question was very generic, and you'd get better feedback if you provided more specifics about your intended usage and requirements.

Actually my question was very specific. The two tires I'm asking about are very similar. Not much tread, low treadware rating, etc. Really they are track tires that can be used on the street in good weather.

I assumed it would be obvious that I wasn't concerned with tire life, or heavy rain, cold weather, or snow. And in any case, both these tires would be bad under those conditions.

Just looking for more folks with firsthand experience with AD08R tires.

Your question wasn't specific. That's not my opinion, it's a fact. You provided more information in this post than the first, barely.

Assuming is always a bad idea and your post didn't make anything obvious. Miss Cleo doesn't frequent this forum.

Uhh, the title of the thread is very specific and (I thought) very clear.

AD08R vs RE71?

I am considering those two tires.

I am not considering other tires.

I am not looking for advice on the differences between slicks vs DOT track vs summer vs all-season vs snow tires.

I am asking for comments from folks with firsthand experience on how those two specific tires compare to each other, or failing that, folks with experience with AD08R only, since I've found plenty of comments on RE71.

Do you have any firsthand experience with AD08R tires that would be helpful to someone considering that tire?

Chill people.

Centerpunch, if you used your last sentence

"Do you (anyone) have any firsthand experience with AD08R tires that would be helpful to someone considering that tire?"

as your thread line, it might have eliminated some of the confusion. Regardless, people will try to be helpful by giving their viewpoints on their favorite tires, even if that was not exactly what you asked. I have learned about options I had not thought of by someone commenting on what they did.

When I bought my Elise, it had AD08R's on it. They were well past their prime, so I don't really have much info to give to you on that. I figured to replace them with the RE71R because they were newer technology.

When you say "which is better", we don't know what you define "better" as. Best track tire of the two that handles a bit of rain on the way home best? Longest tread life of the two? Best absolute track time on a warm day? A cold day? Gentlest break-away characteristics? For these reasons and more, people pick different tires over others, and this is what San is saying you are missing.

I didn't say "which is better."

I was asking for firsthand experience with AD08R, and apparently there's not much of that here.

No worries.

Found some good info on SELOC forums, I think we're done here.

I found one review on Tire Rack's review of the AD08R that mentioned the driver had experience with the RE71R also. Seemed he felt the Bridgestone had more grip, but the Yoko would make the better street tire. Hope that helps.

The reason why you've read so much about the RE71R is because it's a great tire. It's proven on Elige, readily available, and hard to beat in general. I don't know any track-oriented tire that's good in standing water, but I've used RE71R in the wet on my old 2-series and they were fantastic, much better wet performance than R888. I also don't know anyone who has had a negative thing to say about the RE71R for track performance, only complaints I've heard regard wear and road noise.

The RE71R is a tire in a different league than the Yok. The RE71R will wear faster but provide substantially more grip.

I've looked at the Re-71s and went with the R888Rs, because despite the difference in title (Summer vs R-comp) and the difference in wear rating.
From what I've read (no first hand experience, so take this with a grain of salt) the RE-71s and most of these new 200tw compounds act pretty much like R compounds. They wear very quickly, they're noisy, and they're fast at the track.

I had read a couple places that the Re-71s were fast for a lap or two but couldn't handle heat as well over multiple laps as true R-Comps (probably not as big of an issue on our cars) and that they seemed to heat cycle out quicker than some of the better wearing (read NT-01s) R-Comps so in an environment where none of these tires wear out before they heat cycle out, the NT-01s may last longer in a mixed use environment then the RE-71s. Just using these 2 as examples as the NT-01s are known to have lots of heat cycles. Have yet to find out what the R888Rs will deliver.

This seems to be the only counter point to using the new street tires, and again I don't know how much validity there is to it

I assume you know TR tested these, wherein they did OK, but not great. (Don't know if tire has changed.)
