TireRack shows them in 225/40-18 and 255/35-18 sizes. Unless their website is wrong, they are definitely available.

anybody have these mounted on OE F-Sport wheels yet? reason being when i compared the specs on tirerack, the tread width is narrower than the stock Bridgestones. Just wondering if they look funny or too narrow.

You should get the opinion of others but I found they looked meatier in the wheel. It’s reallyhard to tell tlfrom the measurement specs that manufacturers publish as they all have a slightly different approach to measuring the tire. The 4S definitely did not look smaller on the wheel than OEM. Especially with the more aggressive tread pattern I found they looked better.

The PSS’ were amazing so I can only imagine the PS4’s

Do you have any pictures of the 4S on an F-Sport wheel? Thanks!

So I am a car nerd, much like many of you here. Back when I was researching the PS4S and PSS, I found a number of articles and videos that explain what makes these tires different from each other and how they compare
The spokesperson in the first video really emphasized the aramid nylon belt on the PS4S and the variable contact patch. So I did some googling and found a number of articles that shows the Super Sports already have it. The second video does declare that the PS4S is better than the PSS, and the biggest improvement is in wet grip but I doubt daily drivers will notice it.

Point is, you would spend a significantly more amount of money for the PS4S than you would the PSS and get virtually the same tire, with iterative improvement not equivalent to the extra $$ it costs.
If you guys are in the market for tires and are thinking PS4S, I'd recommend getting the PSS's now while they last at a deep discount. I paid $864 for all 4, installed including warranty from Costco =D.
Also, I tried to do a performance test analysis but was never able to find all the data to compare the different performance metrics (braking distance, lateral grip etc.) between the PS4S's and PSS's, I found that to be quite interesting...

You can always go larger. On my 2014 IS350 f-SPORT AWD, I run 255/45/18 AND 225/50/18. The car sits about 1.5 inches higher, which makes sense in the NE, rides much smoother, and I get better MPG (about 32 highway and 19.6 city). I run Continental DWS Extremes and get around 35K from the rears and 75K from the fronts. I've run the PS4's and DWS, they are equivalent in the car. Some tires run badly, period...Turanzas, some Khumo's, etc., in my cars.

Giving my feedback after owning these tires for awhile the pilot sport 4+ on my rwd 350 f sport 235/35/19 in front and 265/30/19 in rear. I’m very very happy with how these tires perform in dry and wet conditions, dry conditions there a tiny bit noisey but driving with music and a loud exhaust I don’t notice them. the grip is very good the car just eats corners. In the wet I have so much confidence, I’ve tried to slide the car around a turn and it won’t budge overall 10/10 for me.

thanks guys. these potenzas just won't die yet but as soon as they do, i will get a set of Pilot Sport 4S's and the FIGS bushings for the front. I'll be sure to post pics if nobody else has by that time

Hi. Anyone has a picture of this on the stock rwd fsport rims? Planning to order same specs 225/40/18 and 255/35/18 but front spec is narrower. I want to have the same stretched set up as stock with big rim protector. Tia cheers!

I'm running a squared setup, 19 x 8.5 +35. Slightly lowered on aftermarket FSPORT suspension. Y'all think I would have clearance issues with the PS4S?
currently got Hankook V12 EVO2 (they wear fast... about 20K on them. 7/32 front, 4/32 rear).
