Mach 1 HP Spoiler

[OZMACH]

@OZMACH Yes, it works fine on the rims, the slight stretch is due to narrower tread width. The look is just cosmetics but there is functional aspect too. Supposedly that tire is meant specially for 10" rims on Mercedes as mentioned in another topic.
When you check specs on Tirerack.com, tread widths are:
PS4S 295/35 = 9.8"
PS4S 285/35 = 10"
PS4S 275/40 = 10.1"
PSS 305/35 = 10.7"
PS4S 305/30 = 11.1"
PS4S 315/30 = 11.7"
SportContact 6 295/35 = 11.6"

From this you can see that the oem size 275/40 has wider contact area than 295/35 so it kinda beats the purpose of going wider. That's why the tyre looks quite a bit stretched. I don't have any stretch with the PSS 305/35. Even that one could have wider tread width but alas. Too bad you had to walk this road down for us but hopefully there'll be better options in the future.

Hi Charlemagne. That all makes sense. Unfortunately though the PSS 295/35’s are not available in Aus. Options with that spec in the Michelin range are limited to either the Cup 2’s, of which I avoided due to wet weather performance, and the PS4S. Both were difficult to find in the sizes I wanted at the time. My only other option would have been the Continental SC6s but with imports affected by the Covid Pandemic (Oct 2021), even they were impossible to find. So was more than happy to finally get my new HP rims on with the set of PS4S’s, which fall within Michelins rim specs. Oh and that slight stretch helps somewhat with the law here. They tuck in a bit .

Michelin Super Sport have 295/35 an 305/35 but i don't know if these tires are good tires like PS4.

I don't what size i must buy, because i just bought too the OEM HP Springs and the adjustable strut mount, i don't know if with these changes the car are more lower than a normal Mach1 and with 35 tires don't fit well, because are a little bit taller.

The 295/35/19 Mercedes’s spec seem to be a lot wider then the specs say lol.. I have them on the back of my 2019 Mustang on stock 19x9.5 PP1 wheels and they look amazing and hook great. I picked these cause on some sites it says 10-11.5 for rim range and on discount tire it says 9.5-11.5 so figured I’d try them and I love them. It says the tread width is the same or within .2 as the stock 275/40/19 but it isn’t even close.. it is atleast an inch wider of tread and the tire itself isn’t stretched or anything. I Think it might be a typo on the tire stats or something . When I’m around my car next I’ll take some pics, it will be a week or 2 because of work but I’ll get some pics.

Hello
I put my example here with the Continental SC6 and HP rims. I have w5300 spring from ford performance.
285/35 19 front
295/ 35 19 behind
very happy! I've already had 4500 miles with them, tracking, highway, rain... they're great
I even thought about going down to 275/35 in front and 285/35 in the rear but I don't know if they would look very stretched with the new Continental SC7, which has a maximum width of 285.

This was an informative read. I'm currently buying a M1 that the PO had put HP wheels on but kept the stock tires. Obviously the sidewalls were stretched way passed spec. So they agreed to order me new tires but want to order the 305/315's. When I read this thread I asked for the Michelin Pilot sport 275/295 set up. They aren't thrilled but said they would do it if they can get em. I'm glad I saw this thread!

Looks like those springs lowered your car close to 1 inch. Any rubbing at all with those tires?
