275/35 Pss.... Wtf

Straight Dave · 10-04-2011, 10:58 PM

So i recently put on the pss on my two back tires and based on reviews and glowing comments about the tires, I thought it would be a no brainer because I usually go with ps2's. Right when i put the tires on it felt different, the grip in the back had gone down tremendously and driving fast doesn't feel comfortable anymore because it feels like they are gliding over the road not hugging them. Idk if there is something wrong with the tires or they really just act like this but I feel mislead if that is the case with all the amazing PSS comments..... End Rant.

Your tires aren't broken in yet. Give it a few hundred miles. The greasy compound on your tires are still there.

PINHEAD · 10-05-2011, 01:10 AM

pretty sure the PSS does not have the greasy initial break-in compound...

bunnn · 10-05-2011, 01:12 AM

Sorry if I was misinformed. My last 3 set of tires had the same effect(RE-11, Corsa Systems, and AD08), I thought it was the same with the PSS. Regardless, don't all tires require a small break-in period? I suppose my tires are a little bit different from the PSS, though.

Donbona · 10-05-2011, 01:28 AM

I do know they need some sort of warm up period..... I had the same initial thought when I drove on them. During the summer I use Falken FK452s on the rear.... instant grip even with over 600bhp.

I’m no expert, but I assume all tires require the use of some type of release agent in the molding process, but maybe not. I recently bought a set of 275/35 PSS for my 18” wheels. As with most tires in my experience, the first few miles were not the best, in terms of grip. I’ve heard great variations in reported “break in” periods for tires. I expect, based on driving style, this period really does vary a lot. With performance tires, I usually drive pretty aggressively at first, realizing the tires are not going to be 100%, but wanting to get the process done. In that scenario, I usually find the tires reach their potential in a few days, not the weeks and hundreds of miles some report, but again, I’m sure it depends on the variables.

Straight Dave · 10-05-2011, 09:34 AM

I have been driving pretty agressively for a little less then a week now about 50 miles per day with the commute and still no sign of more grip.... My biggest fear is having tires that will not grip on a car like the m3

elh0102 · 10-05-2011, 09:55 AM

Hope they come around for you, but at this point, something sounds wrong. I found them to be noticeably better than the PS2.

I'll swap wheels with you and head to MSR......they'll have grip when I give 'em back.......you have my word on it

Also, I've heard that driving slowly on gravel will help with the break in (I've never tried it so I can't confirm)................Phil

That's likely the problem right there. There is always a potential for weird/bad/unstable handling if you mix two different types. Michelin does not recommend mixing the PSS with any other tires, including the PS2.

Most people who have been getting them have been getting sets of four with excellent results.

dexx · 10-05-2011, 03:54 PM

Go do a burnout. If the car is tail-happy with PSS in the rear (especially wider) and PS2 in the front, clearly PSS has less grip than the PS2, there is no way around that. So go wear them in and report back, because I may be getting PSS's in the rear very shortly and I'd like to know if this is a bad idea.

Straight Dave · 10-05-2011, 04:04 PM

I have been driving hard and I can tell they arent as bad as the very beginning and hope they will get better because the difference is still minimal from when i first put them on.

Really do you think it just needs some hard driving? I have been giving it to it good prob for the last 300 miles and just a little change

dexx · 10-05-2011, 04:30 PM

How hard do you normally drive - how many miles did the PS2s last? Also check the tire pressure, may be overinflated.

Straight Dave · 10-05-2011, 04:34 PM

I would say that generally when im on the highway id average around 80 with the occasional moments of 110... but generally im running the car pretty hard. I doubt it is tire pressure but I will take a look at it.

dexx · 10-05-2011, 04:37 PM

Driving in a straight line has the least amount of wear...

Straight Dave · 10-05-2011, 04:39 PM

stock tires were the p zero's and they went out in 8k miles so that was kinda shocking. I do take corners and what not and any highway in houston is not straight, lots of corners.

riyatch · 10-05-2011, 04:55 PM

pss are far superior to the stock ps2 that the car came with. the increased width might also play a factor though going from 265 to 275 in the rear.

Straight Dave · 10-05-2011, 05:39 PM

I thought the increased width would compute to better handling

GregW / Oregon · 10-05-2011, 05:47 PM

I'd go with Ben's theory. You need to change the fronts too. All reviews of the PSS I've seen have been glowing.

GOVCO · 10-09-2011, 09:34 AM

Everone seems to like the PS2s...but next time try out the Bridgestone Potenza S-04 Pole Position tires. Great [period].

Here is what TireRack says about tire break-in:

"Tires are comprised of many layers of rubber, steel and fabric. Due to these different components, your new tires require a break-in period to ensure that they deliver their normal ride quality and maximum performance. As tires are cured, a release lubricant is applied to prevent them from sticking in their mold. Some of the lubricant stays on the surface of your tires, reducing traction until it is worn away. Five hundred miles of easy acceleration, cornering and braking will allow the mold release lubricant to wear off, allowing the other tire components to begin working together. It is also important to note that your old tires probably had very little tread depth remaining when you felt it was time to replace them. As any autocrosser or racer who has tread rubber shaved off of his tires will tell you, low tread depth tires respond more quickly. Don't be surprised if your new tires are a little slower to respond (even if you use the exact same tire as before). Their new, full depth brings with it a little more tread squirm until they wear down."

So...light em up and save yourself 500 miles of boring driving!
