Hey, just want your opinion. Looking to buy RS4 for my car, 15x8 wheels. I'm having a hard time deciding between 195s and 225s... Car is a 1990 miata, BP7 motor, stock power. It's mostly a track toy, HPDE, time attack and auto-x. Car is street driven to go to the track. I was previously on 205 re71r (loved them), but the wear is just too important and these tires are BO at the moment. I know that 225 would be best on 15x9, but I have a hard time putting 195 tires on the car... lol.
Thanks!
Ben

It's not really clear, but is Andy Hollis saying the 205 width contis are better than 245 width rs4s, or better only in the limited scenario of cold/wet autocross?
Almost as fast as RE71s in the dry isn't bad but I'm kind of hazy how the whole size/compound hierarchy is now. I remember RE71s being a quick wearing cheater tire for "street tire" racing classes, but I might be remembering wrong.
A lot of people say "x is best" but best often means "best for my exact application what you didn't know the local weather and rules of my racing series, are you stupid?"

If you look at the tread widths listed by Tire Rack though, it would appear the RS4 195/50/15 runs as wide or wider than some other popular 205s (specifically the RE-71R).
Tread Widths as listed by TireRack:
RE-71R 195/50/15: 6.6"
RE-71R 205/50/15: 7.0"
R-S4 195/50/15: 7.2"
R-S4 225/45/15: 8.0"
Not sure how accurate that information is, can anyone confirm? Since 205 RE-71Rs are sold out forever, I was thinking of trying the RS4 for my next set, I am on 15x8 (stock power).

Of course your mileage may vary based on alignment, weight, useage, etc.
I have a tire probe, but have only gotten data on R7s, no tire temps on the RS4s

34-36ish (225 on 9's) is what we ran for WRL at MSRH on a former SM recently. Felt good, turned good consistent/fast laps and got great wear at -3.5f/-3.0r camber. I'm guessing you could get away with 28 hot, but don't know if it'd be any faster and would likely tear up the shoulder more. Might be one of those situations where it merely feels good, but isn't actually better and could in fact be slower.

I currently run 22psi but that's a 245 RS4 on a 10" for AutoX where I struggle to get heat into them fast enough. Havent had the chance to run big track stuff with my car yet, but imagine I will need to bump pressures up.
120 AutoX runs and 5k street miles on the 949 race alignment though and I just had to flip them due to camber wear now, so I'm impressed on the wear properties.
