Definitive Best Tire for Elise - AS Legal Autocross Edition

The extensive thread on tire/wheel sizes is great, but I am interested in A Street legal set up for autocrossing, so started a new thread.
I have been out of Street tire classes for a couple years and have lost track of the the latest, greatest hot tire. (It's easier when you only have to order Avon slicks!) LOL

So...what is the consensus? What is the hot set up for AS? (Brand and sizes) I am on the LSS wheel size setup (6.5" fronts), but running SSR Comp C wheels. I want to get my little Elise back out onto the Autocross course and have some fun!! (and win of course!)

As a side note, I am thinking about damper upgrades as well...again, must be AS legal. Anyone have anything laying around for a reasonable price?

Thanks!!

Tires - I run 225/45-16 front; 255/40-17 rear

Toyo - my favorite tire(s)
Track R888R - can run street as well just stay away from wet weather (treadwear 100)
Street R1R - good for the street, can track with them but they are a little harder (treadwear 200)

What's your thinking on the 15's? Rake?
Thanks for the feedback...hoping to find an easy button! (We once ran 5 different brands in one season on our ST Honda...don't want to go down that road again!) LOL

I use Toyo R888R (TW 100) on a different car and think they are really great on track but need some warming up. My Elise Cup 250 was recently supplied with the Yokohama Advan A048 LTS which are even better (TW 60) and need almost no warming up and are also street legal.
I was wondering if the A048 without LTS are as good (although designed for heavier cars)? There is no Lotus dealer where I live.

15s for available sizes; OD does not change.

I never went fast with mine in "Street," but I liked the RE71R the best out of all I tried (all of them).

R1Rs are dirtstocker-like in the wet, slow in dry.

Rival 1.whatever the newer ones seem to be _capable_, but I hate the feel of them - not necessarily bad, but the re71r feels way better to me.

However, Nexen makes appropriate 15/17" sizes, and they're fast. If I were still doing the "Street" thing, I'd probably try them - but the re71r is a known quantity, they're fast til they don't hold air, work ok in rain, shrug, yeah, that's the easy button.

.02c!

Patrick is asking about SCCA AS legal tires... i.e., 200+ TW only.

I went 15s for better tire selection, lighter wheels, slightly lower CG and less rubbing at full jounce due to smaller OD. When paired with 245/40/17 rears, the front:rear OD ratio is only altered by ~1.3%. My car had ice mode problems with 16" fronts and it continued having problems with 15" fronts... so I don't think the smaller OD front tire made anything worse from an ABS perspective.

205/50/15 = 23.1" OD
195/50/16 = 23.7" OD

245/40/17 = 24.7" OD
225/45/17 = 25.0" OD

The Dunlop ZIII just came out, so I'm curious how it compares to RE71R. I think the Bridgestone is still a safe bet.

OK...makes sense. Wanting to stay on my 16" wheels, they still have a good RE71 option from what I can see...

205-45-16 = 23.2" OD
245-40-17 = 24.7" OD

If I am doing it right, that is a .9% difference from stock. Make sense?
I don't really want to source out a pair or SSR's in 15", would rather run what I have if I can.

Rivals only offer 215-40 in 16" diameter - We can't fit 215's, right? Ratio actually comes out a little better at .8% from stock, but I am not sure they fit. Have not heard anything about the new Dunlops..will try to see if anyone has any opinions yet.

Thanks for all your help...200 TW tires are still a bit of a mystery since I've been running slicks...LOL.

It feels like the car needs more tire up front, and when I spoke to BWR they confirmed that.
Whatever you go with 15" up front with 225s

I'm thinking of switching to the 15/17s just to get that wider front tire and access to NT-01s. They seem to offer better overall grip and more heat cycles/street miles than the R888s

225/45/15 RS3s and RivalS fit just fine up front on A-street legal 15x6.5 wheels. I ran 225 RS3s in 2014 and tried 225 RivalS in 2015. They're more pinched, but no significant increase in rubbing that I recall. 215/40/16s would likely be fine as well. You might see a bit of rubbing on the outside depending whether you're pushing the limits of legal offset. I experienced minor rubbing with the front track as wide as I could make it within the rules.

While BWR is correct about needing front grip, I'd rather run a 205 RE71R vs. a 225 RivalS1.5.

I ran both RE-71R and Rivals on AS 16/17 wheels testing back to back last year. 245s in the rear and 205/215 in front. I wrote it up somewhere on here. They behave differently and I had no novel input there. The times were more or less matched during my test. I stuck with the Rivals as they multitask much better and punish you a bit less for screwing up. That being said they need heat to work and for lower temps or first runs they tend to be off. Getting heat in the front is a problem. I seemed to have way less ABS ice mode on the Rivals.

I've gone back to the RE-71r but for a different car. I'd probably go to the RE-71r based on WI average temps.

Went with the RE71's - 205-45-16 and 245-40-17. Will report on my impressions when I get it out - someday. (If we get a chance, we may run it on last runs at the Blyethville ProSolo and compare to AS times.)
There's a Honda calling my name first...

Thanks

I found cold 23 F and 26 R (but with the 225) worked for me for hpde tracking. I don't know about for autocross.

How do you get a 225 width tire on a 16" rim to fit up front, under Elise fenders?

Thanks, Ken. The lotus dealer put the fronts at 32 and the rear left at 33 and the rear right at 26. It was not good. hahaha, those guys.

Sadly, I never did get it on the autocross course before I had to load it up for the new owner.

Not doing anything special. Nitron shocks, stiff setting, car is lowered slightly but the tires fit perfectly.
Only a little liner rub on full wheel lock.

Is this on LSS wheels? If not whats the width of the wheels and general offset? You seem to be the only one to do it so far on an elise and I'd rather not go down to a 15" wheel up front
