Need opinions on tires & square setup. NT05 & RE-11

ben1620

I need some help deciding on my next purchase.
Option 1: Re-11's on stock sport Rays
255/35/19 x9
285/35/19 x10

Option 2: Nitto NT05's on 4 rear stock sport Rays
275/35/19 x10 SQUARE

Will be used for around 30-40 autox runs and 5k DD miles a year. Im lowered on swifts and i just got Koni yellows in today. Also have whiteline sways. I know the RE-11's are a much better tire and i'd save $300+ by getting them, but the square setup is tempting. Maybe later i could put RE-11's on the square wheels but i dont want that to factor into my decision bc im want to make the best ax runs with what i have atm. Square wheels + RE-11's is too much $$ right now. Although they may not be ideal, these are my 2 choices so im looking for specific opinions.

Which one would you choose and why? Will one setup wear out tires faster? Would these wheels put me in a different ax class? Actually im not sure what class i'll be in with the koni yellows. Prior to that i was SSM, so any info there would be appreciated also

Thank you much

Buy 4 re11 at 285 35 19 and you are all set. YOU should run a street tire bsp pax class. I can get 10k miles and 180+ rums from them

ben1620

Thanks but four 285's isnt an option for me. I dont actually own four 10" wheels

Me neither, they fit just fine, been using it for two years, on my second set

Per scca rules it would be asp not bsp. Also unless your region does it's own thing the street tire pax options are only for the stock class eligible cars.

Oh yeah you are right, I believe the pax classes are provisional?

I've run 275 square with stock rays and finned great , bumped up to 285 square now. Ran rs3 and ad08's

ben1620

Wow. I thought the bulge would compromise the sidewall and have negative effects on handling. Why do some people still choose a staggered setup? Any down side to using 285 square as a DD?

I read that u used to have 265/285 RE-11's. Which was what i thought to be an ideal setup until this post(aside from a i found deal on 255's). Will you compare them for me? Is tramlining an issue?

Then i read this from Doran Racing and become frustrated all over again.
Is that on 18s or 19s? Is that better for track but not for Autox?

I hate deciding on tires. I wish i had more money.

Found some pics of some 285/35-19x9 Re-11's on a mustang. I'll keep looking for some on a 370. I'd like to see it compared to the rear wheels on 285's





+1 for me

I am sure there is a small safety margin I lose by jamming the big tires, but I have no choice as the car understeers too much and the bigger tire is the only thing I can do to change the handling characteristic of the vehicle. I average a few track days and about 160 autox runs a year, they held up for two years. I guess I don't keep them long enough to blow them. I actually was giving my old set away to local people, but you are too far to take advantage of testing it.

The 285/285 is way better as it gets rid of a lot of the understeer. There is more road noise as there is a larger contact patch, the car does tramline all over the place, but it might partially have to do with my toe setting. I also got better wear on the 285 as I understeer less. Overall the car just drives different, the rear end just steps out whenever you want to rather than getting the constant plow like you would with the 265/285.

My car is stock, the only thing I really can do to change the handling is tires. You can compensate for the lack of front tires by doing suspension stuff, shifting weights around. I believe their tire size is limited by the series?

I have run 18s and 19s on my car for track and autox.

Front



From far


Not sure if this helps, but this is an old video with the 265/285. As you can see, the car just had the death plow and I didn't have to make too many adjustments with the wheel.

This is with the 285 all around. While it still plows quite a bit, but no where as bad. These are all on slower autox, at the fast courses the backend can dance around.

Avoid nto5 for AX. They are terrible cold weather AX tire.

Why not Hankook RS3 or Dunlop Dirennzia star specs or Michelins
