Thanks I too own a Brand New 2019 Gt350 sitting in the garage with MPS Cup 2 tires. I just don' t what tires to run till summer. Do you think a all square IEE 285/40/r19 N Spec would work? I know its alot of money but blowing out MPS Cup 2's on wet pot hole roads is expensive to! Thanks!!
Not too sure how the car's handling characteristics would be effected with a 285/40 N Spec on the front. It's pretty damned wide for a 285. Maybe a call to Ford Performance and speaking with one of the Ford reps. who provide guidance about our cars would help.
Thanks, the Ford Rep stills recommends a 255/40/19 on the front rim even tho Michelin says the Maximum rim width is 9 inches. Go Figure? Cosco has a $110 dollar off deal on 4 Michelin tires before 3-1. They said they would guarantee no scratches on the rims and with lifetime Road Hazard, Tire rotation and Flat repair I might go that way. They have the 285/40/19 MPS N spec tires in stock at $481.99 I believe; MPS A/S 3 plus 275/40/19 in at $287.00, and The 265/40/19 MPS A/S 3 plus at $ 265. It looks like they carry all the Michelin Pilot Sport tires with most models being sold out. I called last night and they said you could order now get the sale price and pick them up when they came in. I have extra rims and will take them in to get mounted when the tires come in, that way I can verify if they scratch up my new rims. Also LMR has the GT350R rims in stock with 7 % off, beautiful R replica rims!
I think, given the GT350's propensity to tramline, that a 285 N Spec might fit but I think you'd have some serious tramlining issues due to the width of the tire. I went with the 275/40/19 in the front and the tramlining that was present with the stock Cup 2's disappeared.
I've been running the 275/40 front, 285/40 rear A/S3's from late fall through to late winter for four years now, and I've encountered lots of wet conditions including standing water. Those tires on this car are pretty solid in the wet, but I've never had it out in snow so I can't comment on that.
Thanks! From my experience with these tires I have zero concerns in the dry or wet. Tire rack and Consumer Reports both give it strong marks for wet performance- including a top rating from CR for resisting hydroplaning (admittedly different sized tires). Dry performance is universally rated as excellent. CR gives it OK marks for snow traction and a weak rating for ice traction. I give it a “meh” for snow/ice. I will say no concerns with extreme cold - they were fine at 0 degrees.
Thanks, After I read your post I decided to order 4 275/40/19 MPS A/S 3 plus tires. The pot holes are horrible around here and the 40 aspect ratio may help. After reading your post i did some more investigating and found the OEM tires front and back had different section width's but the same tread width: 11.4 inches. If I had the money I think I would go with the N Spec MPS A/S 285/40/19. This tire is .9 inches taller, has a smaller section width and the same tread width as OEM 11.4 inches.As all the dimensions are smaller except overall Diameter, .9 inches taller I think it would fit. I don't know if it would rub but some people have lowered their car with OEM tires and they have not complained about rubbing. Also the tires I ordered are .6 inches overall Diameter taller which is a help in driving in winter.
Hello I just read about your tire purchase did you receive them yet? Were they factory new and what was the build date [ the last four digits in the DOT line ] Thanks!
Do you have the OEM Carbon Fiber wheels? If so, I just checked with my local Ford dealership and unfortunately, I was told there are no options available for the rear (315/30/19). Unless, I'm missing any other details, please excuse me.
On the carbon fiber's with the 4s tires, I run 305 in the rear and 295 up front. The 4s is more of a squarish design which make the 305 look like a 315, and the 295 look a 305. They fit and look perfect .......... ;-)
