alright I hate to post this but I just have to know. I'm getting ready to order the rt615s but I want to cut down on my stagger. Right now I have 18x8.5 and 18x9.5 and I have the typical 245/275 40 seris stagger. The falkens have a 255/40 and a 275/35, has anyone had a setup like this or some imput? I'm about to say bunk it, sell my Work front wheels and buy two more 9.5 with 275s at all corners. Anywho through some examples my way
late

 

haha last sentence I said through not throw........flipping idiot

 

What’s wrong with your stagger?

255/40R18 and 275/35R19 should work great as far as electronics goes.

Learn to trailbrake if you feel your car still has too much understeer.

 

I run RT615 275s all around on 17x9 for autocross, it's a pretty good setup

 

Azenis doesn't come in 19", he meant this:

255/40-18 front
275/35-18 rear

this is likely to generate electornic issues

 

I am also running 17x9's with 275/40s all around. If I had 18" wheels and they were for track use only, I would run the 275/35s all around (since I would have the VDC turned off anyway).

 

righty ohh I just wanted to make sure i wasn't making a big mistake.. main reason i wanted to lessen the stagger is for autocross being that i don't want to buy another set of wheels.. I figured this would be a good all around set up for autocross track and drift. Although I might have sick oversteer for drift events being that I use ttwo beatdown 17in wheels with 245s..... then again oversteer can be sex

 

Last year I ran 255/40/18 RT-615 on four 18x8.5 Rays Track rims with good success.

We warned that these tires will still overheat in runs as close as 10 minutes apart in Solo2.

IMO, running non stagger provides a very nice balance.

 

Agree with the above. Non-stagger gives good balance (less understeer). They are good on the track (e.g., for time attacks) on a road course for maybe 3 laps, then they get hot and start to slip and slide.

 

Non-stagger for less understeer +1.

I ran a set of 225/45/17 Azenis on a 3500 lbs AWD turbo car.. it's not going to grease up and over heat on you on a 20 min drive so long as the temps are not past 90F ambient.. you'll be fine..

I would run 275s all around if all possible.

 

I had a co-driver for my Solo2 runs.. even with a 10 min interval, the tires weren't that bad until the last 2 runs (out of the 10 total among the two of us).. temps were 85F ambient.. not that bad, very predictable and controllalbe for a 3500 lbs AWD Turbo sedan on a set of measly 225/45/17...

 

sweet I ordered them today, can't wait to see how they compare to my kumho mx!! gogo new rubwhore

 

Have you gotten these yet? I am interested to see if you have any issues with the elctronics. According to my math the diam. are
F 26.1 (25.6 OEM) you have to add .2 because 8.5 rim
R 25.6 (26.7 OEM)

I REALLY want these tires but am worried about the stagger.

BTW what did you think of the MX's?

 

Has anyone tried 285 rubber? Wondering if a tire that wide would rub in the front?

 

I switched from MX's to RT-615's last year, and the stiffer sidewall of the Falkins made all the difference. Hated the MX's. Sadly, they still get greassy after a few laps. I guess it's time for R compounds.

 

I'm surprised you guys are getting more heat resistance than I am. Are you guys shaving? I'm running full thread.

I find if I don't give the Azenis a good 15 min break between runs (~55 seconds long, 8-12 per day), the front starts to push more easily. Nothing dramatic, but certainly noticeable compared to the MX.

The Azenis definitely have a stiffer sidewall compared to the MX but not so stiff as to ruin the street ride. I'd figure they're .5-1 second quicker than the MX on a 60 second course. The Azenis definitely don't have the heat resistance of the MX but they do work better in the cold IMO.

Price-wise, the MX are a great bang for the buck and have excellent heat resistance qualities (no chunking). As much as I like my Azenis, the MXs would still be the tire I'd use for extensive lapping & street duty.

 

ok so i have a Q? Which would be faster
1-OEM Touring 18x8 with RT-615's 235/255 or
2-ADR M sport 18x8.5F,9.5R with 245/275 MX's
I have the touring wheels now and would save money not getting new rims. I have to worry about stagger so my tire choices are limited.

 

One paper, the wider tires will win.

In real life, the guy that saved the new wheels money to get more track time will win with the OEM wheels…

 

Better bet is to buy 5Zigen FN01R-C's (or other light wheels) in 17x9" and use 275/40s RT-615s or MX's all around. The 17" wheels and tires are cheaper and lighter, you can rotate your tires front to rear and side to side for longer life AND you'll save that money for more track time!

 

How did the VCD deal with that? I read that you have to stagger on a track model?

Did you use this set for daily driving as well? I am looking into my next tire setup.
