Help with EVS100
Alright, I've done a bit of searchin and I can't seem to find the answer. My rx8 has yokohama evs100's but I can't find any place that lists the correct tire pressure. The tire pressure in the manual is for the crappy stock tires, and the only pressure given on the tire/yokohama website is the maximum tire pressure. What's recommended for the yokohamas? Thanks

To keep this thread going, I got a set a little while back. I have only done a little driving on them, but compared to the stock Dunlops, they are quieter, and the DSC kicks in less as they seem to have better traction. On left turns in intersections, the rear would always kick out (I get out of intersections pretty aggressively). The EVS100s don't lose traction. I am going to find another way to get my jollies.
I think the limits of EVS100s is a lot higher that the Dunlops.

I'm just here learning about RX-8s, but I do know a little about tires. Factory pressure specs are a good starting point for any tire. For stock-size tires of a different brand/model, I would always recommend just sticking with them. Higher load, colder weather point toward increasing pressure. Depending how sensitive your car is, small changes might make all the difference. My BMW has spherical bearing upper shock mounts, high spring rates, good dampers, light wheels, good tires, etc. A half-psi change can make all the difference in how it feels under different loading conditions, even for street driving. The sweet spot may be less obvious for a more stock-like car.
My opinion on the AVS ES100s is that they are noisy on the highway and don't provide terribly high grip levels. The tread blocks lack lateral stiffness, so they tend to be very gradual near the limit, rather than crisp, while generating a lot of heat. They were designed for older sporty cars, such as '70s and '80s sports cars, where the chassis may not respond well to the high grip levels delivered by modern tires (think stock suspension 1st and 2nd-gen RX-7s, for example). They are sized and priced appropriately. For the RX-8, I'd much rather have something like a Neova, RE050 or PS2 for street use. I've been spoiled by having PS2s on my daily driver for the last 3 years. More in line with the ES100 might be the BFG KDW. YMMV.

And that is how it will go when asking for tire reviews... one guy yea, another nay.
When these wear out I will look around again. Hard to shop tires, reviews are never quite what you want them to be. So I can only compare them to the Dunlops on the 8.
I looked at the PS2s and they were a little pricey. I went with Yoko because of past good experiences with them. That is, the tires wore out before I had to replace them due to tread or sidewall damage. But yeah that experience was a few years ago. My Goodrich experience was of a few sidewall problems, but I did buy a few for the 1st gen.

1935 lbs. FTW!
Those tires suck, we call them the "Extra Slippery 100's" As far as pressure go with what's on the door of the car. Unless you are autocrossing you don't need to tinker with pressures. Get them to 32 psi cold and leave them there. They'll wear and and get extra loud in a few thousand miles anyways.

For every negative review I read of this tire, I read 2 positives. This will be the case whenever you purchase a tire in the $130-$160 range. As for my experience I coming off the 16" Dunlops so I can't compare the Yokos to the OEM Bridgestones.
The ride so far (about 90 miles on them, I have the 235/40/ZR18 BTW) has been a little noiser and "stiffer" but that's expected coming from the more cush 16"s. The positives have been the responsiveness and traction which respectively are much better.
As for the wet traction I would like to hear more reviews about this. Again I've read good reviews, avg. reviews, and poor reviews.

I've been keeping them at 36 psi in hot Florida weather, so that is probably 33-34 psi. I think the tires are great and provide lots of grip without sacrificing ride quality or being to noisy on the highway. I did not have the car when the stock tires were on though, so I don't really have a point of comparison except our BMW Z4's runflats which are rough and noisy as hell.
