Hi - Welcome to the forum, lot's of GREAT information here and lot's of GREAT folks to share its with
As far as the 255/40/21 on the front wheels. No cause for concern. 245/40/21 is not an exotic size, but it's a size that's hard to find in a non-RFT tire. However, a bigger concern is the mismatched tire branding. A question, are both brands of tires RFTs? HiPo tires have performance characteristics designed into the tire by the manufacturer and mixing different brands can use issues in some extreme situations when you least expect it.
BTW a few members here are running 255/40/21 in front. I am running 255/40/21 and 295/35/21 (non-RFT) PS4S on aftermarket wheels on my LC, and they were far from being "much cheaper" BTW.
And most of my chrome is wrapped with black carbon fiber 3M tape. No pieces had to be removed during the wrap procedure.

Super - good callout! I believe the fronts are also runflat but I’ll double-check when I see them in person. I’ve actually run MPSSs and PZeros on my Mustang and found the MPSSs to offer better lateral traction - so if anything the PZeros might bias the car slightly further toward understeer. Shouldn’t be a big deal.
I’ll send y’all a pic if I can after this weekend. So, so excited.
255s are better than 245s especially if it's switched from non-rfts but Pirelli Pzeros are far inferior to the Michelins in the back. I have no idea why anyone would buy Pirellis over Michelins.
It'll be driveable without issues but it's not going to be at it's full potential which isn't a problem if you're not driving 10/10.
^^^^Again, I must disagree. Different Manufacturer's HiPo tires have differing construction, tread design, and handling characteristics. You MAY run into trouble.
255s are not necessarily better, but they are a bit larger (width & hight) and they will fit on the LC's 8½" wide wheel.
I took the plunge. Turns out while it does indeed have 255s up front, out back it has 295 (still 35 aspect ratio) MPSSs. Drives well regardless. Slightly loud on grainy/concrete road surfaces, but the compliance is superb. The diff puts power down well too. I will probably switch to all seasons if I can find them in 21", since where I live it's pretty much always 45F and wet, and in my experience summer rubber doesn't benefit you much in these conditions, unlike when I used to live in warmer places.
There's a nice view in this photo, but as it was foggy today I guess you'll just have to take my word for it -
^^^^Looks like you have the stock 21" wheels painted black. Looks Good But, 295/35/21 is too wide a tire for a 9½" wheel. 285/35/21 would be fine. I was unaware that the Michelin PSS came in the 295/35/21 size

You have 8½" and 9½" wheels front to rear.

You’re right! I checked and they’re Latitude Sports, not Pilot Super Sports. They seem to drive fine and the sidewalls don’t protrude from the wheel too much?
So you have the Pirelli P-Zeros on the front and Latitudes (that are too big for the wheel) on the back Not something I would do. is a telling statement

It’s definitely treason but we covered 300mi this weekend, lots of twisties and wet pavement, and had an unreasonable amount of fun. I’ll probably enjoy them for the summer and switch to all seasons when convenience permits. Michelin can bite me for not following their marketing instructions I suppose haha. Thanks for the input though!
It it’s anything like mountain biking, the rim has a big effect on how much the tire actually balloons out. I’m guilty of running big balloon bike tires on too-small rims, so we’ll see if this causes problems. So far so good.
