So due to the RE71r back order of 275/35r18 and 285/30r18 into July, I'm trying to figure out what to put on my set of APEX ARC-8 to autocross with this year. Stock e90 in F Street.

Front: 18x9.0" ET30
Rear: 18x10" ET25

A few options:

RS4: 285/35 square
RS4: 275/35 square
Rival S: front 275/35 rear 315/30
AZENIS RT615K+: front 275/35 rear 315/30
NEXEN N FERA SUR4G: 275/35 square
DIREZZA ZII STAR SPEC: 275/35 square
RE71R: 265/35 square

What do you all think? If it makes a difference, I will be competing at the Delta and Wiregrass regions. Delta has a purpose built AX site, with nice pavement. Wiregrass is a huge, high grip concrete site with speeds of 70+mph.

My vote would be to go with either:
RS4: 275/35 square
or
If you think you can clear a 315 in the rear, go with:
AZENIS RT615K+: front 275/35 rear 315/30

Why do you recommend the Azenis over the rival s?

I have a set(4) of new 275/35/18 RE71R that I can probably ship to you if you're interested. PM Me pls

the nexen sur4G is looking pretty good. I don't think you will like a pinched Rival. I liked the 315/30-18 out back on Hoosiers, a lot but the re71R seems to handle pinching better. The Rival is no Hoosier

Also the RE71R in 265 square has won a lot of FS events. Don't sneeze at it

I think you'll be happy with the RS4.

TR has 275's available as of 5/10. Go ahead and pre-order. Worst case scenario is they get delayed and you cancel. FYI -- TR and DTD are not the only folks that get these tires in stock. OnlineTires and other suppliers have them if you call around. My local guy gets them in and holds them for months until I need fresh rubber so I don't have to store them.

I put in an order for 275s about 10 days ago. A TR rep contacted me to tell me the expected delivery on 5/10 was already allocated and are therefore on back order bc no more we're coming.

I went ahead and bought 275/35 rival s instead

I've heard great things about the RS4's.

[dnoble37]

Well, too late for me. Im committed to the Rival S. Hopefully I like them.

Ive read a ton about all the competitors in this 200tw realm... seems the rival s was my best plan B. There are some minority reports that the rival s can be faster than the re71r. Seems to be a driving style thing.

...hopefully my styles fits.

How did you like the Rivals compared to the RE71R'S

[dnoble37]

I like them.

I wrote up something in the F street AX thread.
