Default Yokohama A052 (2019) vs Bridgedtone RE71R vs BFG Rival

So the updated A052 has started to win some regional SCCA event classes beating out the Bridgestones and BFGs. Figured I would start a thread about it...

Early reviews say they are better at managing heat and may last longer than RE71Rs.

Tire Rack and Grassroots will probably have reviews soon.

I noted they don't have 19'' tire sizing, guess factory RA wheels are out.

Checked Yokohama's website, they've got RA tire sizing there - guess TR doesn't.

I ran them on my '18 STI last year; they really need camber. 3 of the 4 tires corded within 1.5 days on track. The best I could get out of the front was -1.7ish, and the rear close to -2. They didn't wear down to the cords, either, but chunked. Pretty fast tire, though, I liked running on them. They were over 3 seconds a lap faster than the stock Yoko Advans at Palmer, which is a fair bit.

Are you sure this is the same tire? This new A052 was just released.

Edit: They increased the tread depth this year so they will be legal for SCCA autox. Previously they were below the minimum tread depth. There may also have been a compound change.

I'm not waiting for any reviews. A set of A052 245/40/18's will be going on my STH car very soon. I'm sick and tired of the RE71's extremely narrow performance window and BFG doesn't make a 245/18. I'd pick the Yok's over the BFG's anyway since I had really good luck them in the past (2005). A competition tire like the RE71 should not have noticeably more grip at a tread temp of 95F compared to a tread temp of 120F. I know part of the reason is there is an awful lot of weight on the fronts, but my rears get greasy at 100F+ tire temps too. I don't have a problem with wear or temp distribution with the RE71's since I have 3.25 negative front camber. I have just never driven a tire that can go from awesome to suck so fast.

The only change between last year and this year was to go from 6mm of tread depth to 7mm. Entirely done for legality with AutoX and OLOA. Compound did not change.
