Not really. The front ride height will be a little higher with the 285/40's, and that's about it. With 275/40 fronts and 285/40 rears, both ends get a lift of about 1/4". The ride height changes but the stance stays the same. With 285'/40's up front, the front end will be up by about 3/8". I doubt anyone will notice the 1/8" extra height. As for improved handling with wider tires, well, they're all seasons - very good but not spectacular, so the extra width doesn't do much for you.Is there any difference between going 285 all around or going staggered like you have?
And if you need more help, call them. Their tech folks are pretty good at helping you find the right tire for where you live and the condition range that you may experience.Try going to tire rack and searching for tires in the OEM size. That will give you a list of all available in that size and they have good ratings to see which one works best in certain situations like wet, cold, snow etc.
Don't know if they'll work on a GT350, but I put a set of Cooper Zeon's on my MACh1. I bought a set of HP replica wheels that are 19x10's squared so I can rotate. They're discontinued, but Tire Rack shows them still available in 305/30/19's. Weird that OEM for the GT350's are a 35 series and the MACh1 is a 30 series.
Anyways....I've had them now for 5000 miles and have no complaints. Would I track them??? Probably not, but they are a 50K mile tire that do the job on the street.

Agreed. Just go with the supersports. Don't floor it out of your driveway when its 30 and you'll be fine.OP, why in the world are you making this so complicated? First off, GT PP wheels will not fit. If you use spacers for any other wheel other than stock non-R specs then you need longer studs in the front and open lugs. Secondly, for tires go with super sports in OEM size. Or PS4’s in 30 series. That’s it, done, end of story. I wouldn’t go tracking or hitting the mountains in 30-40 temps either way in any tire. For daily driving you will be JUST FINE.
Here’s a thought: I just sold my gr350r and I kept the custom Savini (5 Double spoke) wheels and almost new Continental Extreme Contact tires mounted and balanced! I bought them for all season driving, then sold the car after 300 miles. The wheels are 20” x 10” front and 20” x 11” rear. They look new…and they practically are! I bought 20” wheels so cleaning around the brakes would be easier, it gave me a little more ride height so no scraping, and the Extreme Contact tires are excellent! Tires are 285/30zr20 front and 305/30zr20 rear with just 300 miles on them! I’m selling them all for $2800 OBO + shipping and in throwing in my hub centric 15mm spacers for the front end. But unless you have the “R” you won’t need them. 717-891-2062. SteveHello Everyone,
I’m new to the community and just recently picked up my 17 GT350.
I know this has been discussed but I can’t seem to find a thread with direct answers. So please forgive me if this question has been beaten to death.
What are my options for all season tires that fit on stock wheels?
I’ve looked at the pilot sport all season 4 285/40/19. But I would like to know what are my other options?
