Yokohama a052 which size?

[shootnjunky]

running a square 18x10 setup

not sure on 265/35 or 265/40?

preference and why?

Thanks

35. 40 is too tall up front and will hit stuff.

[Kelse92]

265/35 square is the go-to setup for now.
I am looking at trying some others this year possibly as well. Will report back if/when I do.

265/35. Even if the 40 would fit (which it might not), take the 35 for the lower weight and gearing advantage.

How many people are running 295 A052 squared now?

I think slicer had a set?

I also recall fsmtnbiker having 295 Nankangs which would be similar square.

I think the nankangs run much narrower in comparison though.

I don't think you'll find a ton of people running that setup. If they are it would likely be for either autox or a time attack series/class that mandates 200tw, on top of being able to fit a 295 up front - this limits the number of potential users of this setup a lot. For lapping use there are much better options from what I've heard. They are a very fast tire but wear out very quickly and don't hold up to much more then 2 hot laps before getting greasy and overheating.

275/35 is great as long as it clears your strut


40 sidewall definitely way too tall...
Below on 18x10 +15 front, +10 rear
Rubbed on freaking everything.

I ordered 275/35 and we'll see... I've researched and plenty of people do 275/35 square

Yea, I'm either running 295 or 265 square A052 in street class for GTA, as nothing appears to be faster in that treadwear rating. I normally just run 275 NT01. Speaking of which, why have they never offered a wider NT01 that we can fit? Would be so nice to have a 295 NT01.

Makes sense. For your application the A052 is a great tire. Are you able to fit a 295 up front?

Regarding the NT01 - I'm not sure. I sure wish they did. The 305's are simpler to big being a 35 profile to run up front. That's the reason I went to the RR, they offer a 295/30 and a 285/30. Very similar to the Nitto overall and a bit quicker. If people want something very similar to the NT01 they can either go RR in 285/30 or 295/30 or the R888R also comes in a 295/30.

I think I can probably fit the 295 up front now on a 10.5. Just did the 140mm spring conversion and helper spring delete on my KW CS, and at the height each perch sits now, it appears that a tire with the diameter of a 295/30 would hit the shock body before the perch (if wide/offset enough). Was running 275 NT01 on a 10" at et13 before without rubbing (after self clearancing the plastic fender lip) at only -2.8deg camber, so more camber is available and likely will be desirable anyways.

Yea, the RR is appealing, I just feel like that extra 50% tread depth of the NT01 is nice for someone who does a lot of events. It is 4 vs 6 32nds, correct?

Yes, that's correct on the depth differences between the two. I haven't gone through my first set of RR's yet though, but so far the wear has been very good. I'll need to see how many heat cycles I get out of them compared to the Nittos which I'm more used to.

I'm running a 140mm spring on my KW competition setup. I recently switched my helper spring to a lower rate helper, which is turn compresses more than the stock helper and brought my spring perch up 12mm. This gave me the clearance to run 295's up front. I'm at -3.7* though. I'm not sure how similar the shock bodies are between the two but I have 'plenty' (all relative) of clearance to my shock body, the perch sits near the top of the tire now (where it begins to round off) and has about 4mm of clearance. I'm going to go into more detail on this when I post an update in my build thread.

I find the A052 lasts much longer than any other 200TW tire in terms of overheating on track. I'm usually able to go 15 minutes on track before I feel any slip. Things like the RE71R, AD08R and RS4 go greasy much faster than the A052 and have less max grip overall.

I was able to get 3000 street miles and 4 track days out of a set of A052s in stock size (245/40 and 265/40 18"). Kind of fast wear but that's enough for a year of driving for my car.

A052 doesn't have 275/35, only 275/40...

Interesting, good to know. I've heard they react similar to the RE71's on track - good for 1-2 really fast laps then they grease up because they overheat. Bigger sizes would overheat less as well. Was that on a E9X M3?

Yes, I run them on my e90 M3 6MT. It's a heavy fully loaded street trim with KW coilovers, Dinan camber plates and stock wheels. I've been tracking the same car for 10 years.

I find I can go most of a session on A052 before it gets greasy. RE71R can only last 2-3 laps before it gets greasy. The A052 is more consistent but it wears much faster.

Not really a factor for track days, but the A052 is also very quiet and comfortable on the street. Very cool for a track day tire with so much grip.

Ahh that makes more sense application wise. I think the 295 should fit on a 10.5 or 11. I would run the 295’s on my car for autox if I could, but class limitations mean I can’t so looking at the other size options personally.

Yea I'm hoping 295 can take some heat.

I have square 295/30-18 A052s on 11s on my E92.

The wheel is as tight to the shock body as possible, spring perch above the tire, and it takes a minimum of -3 camber to slide inside the fender. But they fit fine.

So good!! 295 front is insane. Only if I had unlimited tires
