355/30-19 Kuhmo Ecsta V720 ACR on ZLE
 

I saw on here where one guy is running this tire, however I couldn’t find photos so I took a few during my installation process so others can see some details. The following are all before photos:

And here are the after:

That's a monster!

Looks great.

Did you move the wiring harness? It looks like the tire is definitely hitting the bump in the wheel liner. Fender rub under hard cornering would worry me as well. I think the other guy said he has experienced some fender rub.

Also, I don't see any pics in the first post?

Sorry, some of the photos turned on me and I was trying to fix but to no avail. So far nothing is rubbing and I just took a short drive so about to go double check everything. I will post some side by side comparison pics here shortly.

Yes, you have to move the wiring harness. It rubs but just barely. Time to go to work so I'll have to finish this later.

Side by side comparison:

I will post some better pictures when the weather is more cooperative.

Those are some serious meats! Looks awesome!
Are you going to track it? Wondering if this will induce any understeer?

I do plan to track, autocross, and drag race. But I am just in it for the fun and enjoyment of driving. I’m not worried about being the fastest or winning races. So if it takes a little away from it’s performance capability it really doesn’t matter because it’s still far more capable than my skills lol!

You should try throwing the 325 G3Rs on your front rims to see if they clear. Not sure if anyone has attempted that yet.

I really like these as a track tire option for the price and performance, I dont think 325 3R will fit in front on ZLE.

You can either run 305 3R, or 315 Hoosier R7 or 315 PSC2. I'd try the PSC2 first because the idea is to have a set of 4 that wears better than 3R, and nothing wears faster on track than 3Rs on the front of a ZL1.

Yeah I doubt the 325 would fit up front too. It’s one thing to add width in the back where the wheel only moves up and down, but up front there’s also the turning to consider. I will have to pass on being the crash test dummy for that one lol. Here’s a good pic of the new rears.

I run PSC2s in 315/30/19-F 345/30/19-R on track and tested these in the most grueling G forces of the banking at ACS in Fontana. They fit no rubbing, or at least none that cuts the tires.

345 PSC2 looks badass on the ZLE, this may be the only tire that looks more badass :-)

I used to think 285/30/18s on all corners looked wide on my Evo X.
