Basically ran the same times on both tires at both sites. I liked the car a lot more on the BFG's and they paid better contingency, so that is the route I took.

Neither tire can hold a candle to the Yoks.

Pretty much what he's saying but the heat tolerance on BFGs is significantly better. Especially if you are dual driving. Between the Bridgestones and BFGs you will likely never overheat your BFGs with a co-driver but with Bridgestones you can. The BFGs also recover better if you exceed your maximum cornering grip. They're more sluggish on turn-in (they are wider ever so slightly too) but offer better feedback to the driver in sweepers.

Curious about this, for the guys that are running -4 degrees of negative camber or more that do occasionally take their cars to the track. Has that much negative camber, negatively impacted braking performance ?

I'm at -4.2 of camber. No issues on track

I'm at -4 degrees. In the bit of data I've looked at there's no noticeable braking distance difference between my current -4 and last years -3.2 degrees.

For those with ao52, has anyone flipped them on rims? I am used to doing this on many other tires, but haven't seen anything mentioned about this on the ao52.

Molez93 · 08-04-2021, 12:41 PM

My Yokohamas are wearing evenly.... amazingly so really. Haven't considered flipping because there's nothing to address on mine ~50% in.

Breezio · 08-04-2021, 12:51 PM

The amount of camber you should be running for an STX build will yield pretty even wear for A052s. My last set wore even all the way to nearly bald at ~130 runs.

steverife · 08-04-2021, 01:22 PM

Same. My first set is around 160 runs. Flipping never crossed my mind.

I flipped a set last year and there was no noticeable change in performance one way or the other. Not going to bother flipping them ever again.

Did anyone take tire temperatures readings of the Inner-Mid-Outer edges of the A052? What camber and psi do you run them at?

Kelse92 · 08-09-2021, 11:06 AM

In case anyone wanted some data on Nankangs, mine have 66 2-driver hot summer runs with all but 10 of those on concrete and they're looking pretty done for.
I'm going to try and squeeze another 10 runs out of them next week, but useful quality runs out of them were gone by about run 55 I think.
Served their purpose as a good-stop gap to save the Yoko's for nats but I think Falkens will be my answer for local events the rest of the year.

lack of tread? heat cycled? what exactly is the problem.

I'm 52 runs on my Nankangs and they are performing fantastic. Still have tons of tread left.

Lack of tread. They could handle a few more heat cycles but they're looking pretty close to slicks at this point.
