I'm curious to know how many miles everyone has or has gotten out of their stock Michelin PSS tires? Obviously Driving styles and suspension mods play a roll but just looking for a baseline. Also has anyone switched to something different? If so how do they compare?

 

I checked out a CPO '15 RC F with 7k km (4k miles) and the tires were about 50% worn.

 

I bought my car in August 2015 and changed the tires after 1.5k miles to All Season tires to go to a snowy place. It's not even worn yet. I still have to measure it how thick it is. Then, I just got new 20" Ferrada FR2 rims which I cannot use the OEM Michellin PSS. I might have to sell it if ever.

How thick/deep is the original Michellin PSS compared to the 50% you saw?

 

Can not tell you total but here is a tire image after 9400 miles
and measurements on all tires at 9100miles and 4300miles. Bar graphs are in 32nds.

 

I ran Michelin PSS on my 08 G37S for several years before buying the RC F. Tire life on that car was typically 10 -12 K. I drove that car fairly aggressively as I do the RC F, and I feel that the trade off of wear for performance is reasonable since the PSS are not outrageously priced. I went through a four or five different sets of tires on the Infiniti but didn't find anything that was near the performance of the PSS.

 

22,000 miles and I need to buy third set.

 

I like the PSS's a lot so far, 8500 miles and about 1/2 gone.

 

If you drive aggressively in the twisties, they'd be gone much sooner than they should. The problem is not the tires, but the stupid front alignment on this car. You can hardly find a better performance street tire than the MPSS, especially for the money. It's better than the competition in every respect, especially in the wet. Not worth getting anything grippier (like cup tires) unless you change the front suspension (camber arms) to allow better alignment specs. For people who don't like to push the car hard, the Michelin 'ultra high-performance all-season' A/S 3s would be a much better choice. They have a 168-mp sustained speed rating, are close to the PSSs in summer, and significantly better in winter, with much better life expectancy as well.

 

So this is an update to my previous post above. This is personal record for me - I have been running Michelin PSS on my G37 for the past 4 yrs, went through I think 3 sets, never exceeded about 14K with a set. Now I admit I am a tire-squealing g-pulling kind of guy, even more so now with the RC F. Right now I'm sitting at 15.1K mi and estimate I have another few thousand in them. Seems odd since this is a heavier car and easy to burn rubber with the V-8, so I'm at a loss to explain it but not complaining.

 

Suspension set up.

 

Are you referring to the fronts or rears? There is no way they wear at same speed

 

Also the Michelin PSS are on month minimal back order, since every performance car is using it as oem. My next set will be potenza re11. They are stickier and perform better than PSS.

My question is has anyone increased the size of the rear for more grip? The wheel is 10 in and I'm thinking about installing 305s. Any one done it?

 

^^^^I have RCF wheels on my ISF. I'm running 255/35 in front and 295/30 Bridgestone S-04 in back. The rears are .6" less in OD than the stock 275/35. tire on the RCF. 305/30 might work on an RCF and be closer to your stock OD.

^^ the so4 are notorious to be smaller than other brands. On my 370z the diameter was about an inch smaller than my previous set (Michelin a/s 3) with same size 285-30-20, so it made the wheel/tire looked much smaller.

 

^^^^Not True. Yes, the tread is not as wide on an S-04 vs the PSS, but the cross section and the OD are (and have to be) exactly the same to meet the DOT criteria.
