I think nando gave them 40 heat cycles to get the tread life he wanted.

I've got about 4 hours of track time (3 events), a couple autox's, and street driving from march through september of last year (~8k). I'm expecting them to last until the end of summer, with a couple track days and hopefully 8 -10autox events. They were lightly used before I got them too.
and unfortunately, treadwear is 100% useless for predicting tread life, except that 800tw grandma tires usually get old and crack before the tread wears out, and sub 200 tw tires usually last a summer or two.

I agree, otherwise you wouldn't see treadwear 30-40 autocross tires lasting a full season and some guys drive on them to and back from the events.Mtech1 v8 build thread - https://www.r3vlimited.com/board/sho...d.php?t=413205

the R888s have nearly that and still tons of life left. I expect them to last 2 summers (+ a couple HPDEs and autox). The ES100s barely lasted one.
The one thing that may bother me about running r-comps on the skreets, yo, is the noise. Some of those things sounded like your drivetrain going bad when you're driving, my friend in an evo has some 255/40 A048s that he rides around on and they're easily louder than any other sound the car makes at 35mph. I'm sure it's something I could get used to, but normal passengers would probably be a bit discouraged that my 25 year old shitbox in "great mechanical condition" sounds like it has no wheel bearings.

the R888s aren't that loud, but the sidewalls are damn stiff, it feels like you've doubled your spring rates. It probably makes most of the noise at 25mph and below, above that it's fine.
alignment before was actually a lot less agressive - about a degree and a half less camber up front, and half a degree less caster. front toe set to stock. My rear camber/toe is actually well within stock specs, thanks to the odd design of ix subframe bushings. I was going to go with weld in plates, but after having the alignment checked it just wasn't worth it.

Old tires doesn't matter.

-Correct ET25 offset for maximum track without spacers
If they were 15x8 I bet they'd be really popular outside of spec e30. Pretty good looking wheel.Originally posted by z31maniacI just hate everyone.
No need for discretion.
