Kumho Ecsta PS91 vs Michelin Pilot Sport 4 — Compared (September 2026)

“Follow up on new wheels/tires for ZHP Well new wheels and tires are on aswell as aligned. I love the tire and fitment setup but really do not like the gunmetal grey color especially on imola. I will feel it out for a while but probably eventually powder coat to OEM silver. Wheels specs are 18 x 8.5 x ET50 with 255/35/18 Kuhmo Ecsta PS91 all around. -2.5 camber in the front and -2.8 in the rear.”

“New meaty tires set up installed, now I can order spacers Went up tire sizes and they definitely fill the gap a bit. First time running sticky kumhos on anytime so excited to see how they turn out.Specs are Kumho Ecsta Ps91 235/40/18 up front and 265/40/18 in the rear. Read more”

“New wheels and tires for my ZHP My old wheels were super beat up and tires were showing wire so I figured I’d upgrade both. Was able to get these freshly powder coated squared set (18/8.5/et 50). Im excited to feel the Kuhmo Ecsta PS91 as they are a budget friendly performance tire. 255/35/18 tires all around”

“275/40 Square Can Fit on a Sedan Shout out to TireRack for having great information on actual tire size. Ecsta PS91 265/40 and ExtremeContact 275/40 has a tread width and section width difference of 0.1” and 0.2” respectively. Tires fit just about perfect. No rubbing so far, and don’t expect it to rub bc of the relatively minimal width change Really goes to show that tire brand matters for fitment Read more”

“Surprised by Michelin Pilot Sport 4 tires - 2024 M440i Hey, BMW community. A year ago, I was lucky enough to order a 2024 M440i GC Xdrive. Spent hours driving different BMW's, tweaking my order sheet before my allocation was filled. Got the adaptive suspension, with 19's on Pirelli run-flats. After a few months, my San Remo GC was delivered. GREAT car. Now with ~17k miles, it was time for a routine service. And, apparently, new rear tires. Decided to just replace them all at the dealer. Went with what they recommended; Michelin Pilot Sport 4 (Star marked). What an upgrade! Steering feel, precision, comfort AND quiet. Anyone on the fence about the Pilot Sport 4 - highly recommended.

“Michelin Pilot Sport 4 tires are noisy (a followup) I have been asked on this sub if the PS4 tires on my wife’s Bolt are noisy, and I wasn’t sure how to answer. Well, we made two 60-mile round trips this past weekend, mostly on highways with 55 and 70 mph speed limits, and I have to say that the tires are kind of noisy. Certainly not as quiet as EV-oriented tires are. The grip is fantastic, so we really like them. If you are sensitive to noise, though, these Max Performance class tires are probably not for you.”

“I just installed A/S PS4 from Michelin on my BRZ recently & man they are so nice. How quiet it is, is wow, night and day. They handle quite nice except when it's still cold (sub 40F) on highway, traction control triggers but it may bc I'm lowered and yet to do my alignment. I don't know compared to stock, I was on Falken prior. I am using different tire set-up then stock however. I have 245/35 at the front and 265/35 in rear. My only regret is not going up to 40 on the sidewall for more meat. This is on 18" wheels.”

“Those are Pilot sport 4 (all season). If it had s after the 4 it would be the summer high performance version. I put the pilot sport 4 on wife's GTI autobahn 2016. Great handling tire, stiff side walls, not the smoothest ride but best overall.”
