Michelin Pilot 4s Tire Options

[Lorne34]

Also considering the exact same setup of 305 square with the 4s sizes, appreciate the input of others as I'd really like to get into the 4s on stock wheels if at all possible.

For those that have done this it looks like we're looking at about a 2-3 mph discrepancy in what the speedo will read vs actual speed if I'm punching things into this calculator correctly?

Yeah I was wondering about that as well going to a 20 tire vs 19. How much of an effect on the speedo...

Speedo can be fixed using FORScan. I find it's a useful thing to have for several reasons. You just need to buy a cable to connect your laptop to the OBDII port.

Good seeing you in KY! While I am running the 315s square as you saw (vs. Nick's 305s), I'm doing so on 11.5" wheels front and back. The stock wheels would technically work with 315s, but the fronts on 10.5" wheel width might be a little bulged and may make your turn-in a little squishy. I think if you aren't going wider wheels you'll probably be better off with 305s.

Hey Chip,
Great to hear from you! I felt a little self conscious at first kneeling down in the parking garage staring at side walls! I love the look of the original OEM stock wheels.. so much that I swapped out the refreshed the 2019 stock black gloss wheels for the satin black from 2015-2018.
I think it's 305 squared for the win!
By the way, my back end kept kicking out on those hairpin elevation turns on day 2.. so much so that I questioned whether it was my mpss. When we got back down I asked around and everyone from the 4s to the cup2's were experiencing the same thing. A bit damp on those roads up there!

Here's a vote for 305 square 19's. I've been running this setup for awhile and have zero complaints. The 4S tires are great!

What is your opinion on going to the 20" tire? 305/30/20

Just a question occurs to me. Have been running 4s on front and PSS on rear as oem sizes. Trying to avoid 30's all around as I scrape occasionally as is. But if possible and I went with 4s 305/30 square on oem wheels, and as the 4s are directional, would rotating front and rear on same side extend tire life since this car does eat tires fairly quickly?

My understanding is the stock wheels are different sizes front and back so I don’t think u can rotate them

I have given up hope that Michelin will produce the gt350 tire in oem sizing (35)

Pretty much nobody makes 305/35/19 if that makes you feel any better. Michelin Pilot Super Sport or Cup2. Nitto does as well (I would never recommend Nitto G2 to anyone, ever, they suck that bad). Firestone Firehawk comes in that size but I’ve never used them personally. There are others that have and like them but my guess is they’re not quite on the same level as Michelin or Continental.

Thanks I’m pretty much settled on the 4s tires now it’s just a matter of final decision on the fronts
295//19 or 305/30/19 like in the rear

Did you consider another brand to see size options? Contrary to popular belief (you'd never know it hanging around this forum), and as amazing as they are, the 4S is not the end-all-be-all tire. There's some amazing competition out there. Conti Sport 02 and GY SC3 just to name a couple.

And also, going from a 35 to a 30 is not near as drastic as it sounds in the scraping departing. It did not change my lifestyle at all.

I buy the Super Sports

If I was tracking more I would swap my mpss a different wheel set
may hang unto them and do that down the road
for now I want a more compliant GT Road trip tire
