OK, I have a 2011 Conv. GS and want to buy new Michelin Pilot SS tires non run flats. The dealers I have talked to say I need 275-35ZR18 for the front and 32530ZR19 for the rear but on here some people have quoted different numbers, such as: 275 for the front and 345 for the rear and 295 for the front and 345 for the rear. I am very confused!!! Can one help me out? Thanks

Stock sizes are 275-35ZR18 front and 325-30ZR19 rear. Some guys upsize to 285/18 front & 345/19 rear to fill out the wheel wells & if pure cosmetics are your bigger priority then go for it.

But if performance is top priority, then the stock sizes are a few lbs lighter & imho they're more appropriate for the GS, as the Pilots SS's are much stickier tires than the stock spec GY F1's & 285/345 is overkill..even for the Z06.

Tirerack.com will answer this question and leave no doubt.

Might also discover a price that you can use to negotiate with your local dealers.

Or buy from tirerack.com if your local dealers won't, ahem, deal.

Edited: Changed info on my PSS tires. PSS is not available in a runflat in Z06/GS size. The runflats I have are PS Cups in ZR1 size.

I have the stock size PSS on my Z06. If they were available in a runflat that's certainly what I would get!!

I ran them on the track at Daytona last month and they ROCK!!!!!

I would STRONGLY recommend you just go for the OE size PSS - they are a FANTSTIC tire!!!!

Just MHO, YMMV.

BTW, just added some pics of the PSS on the track.

Here's my Z06 chasing down a Ferrari - blew past him right after track out:




Here's a closer look at the PSS cornering at about 1.3 G's - I think the stock size is perfect on a Z06/GS:

Driving around town not on the track plus size, if you like to track the stock sizes

I am running a set of Nitto Invo's on the front and a set of Nitto NT-05 on the back of my GS right now. Although I really like the Nitto's, I was considering a set of the Michelin 'Pilot Super Sport' tires as my next replacement.

My question is how do these Michelins wear in comparison to the Nittos? Right now I am just looking for a set of tires that will last a long time with easy driving.

I just ordered the Pilot Super Sports in stock GS sizes (275/325) on Monday from Discount Tire. Should have them mounted on Friday. Stick with stock sizes and know everything is correct.

Bob, are you talking about PS2 runflats...I was under the impression that the PSS was not made in a runflat yet....?

Yea...clear that up Bob.

PS2 Runflats are available in stock GS/Z06 sizes, PSS (Super Sports) are currently not. All I know is that the PSS is a fantastic tire in all weather conditions except snow. Even in 8 degree cold they are good.

Yes Chris, you're correct - the PSS isn't made in a runflat yet.

It will be a runflat for the C7, but it's not available in a runflat for the Z06/GS.

I bought 2 sets of tires at the same time from Discount Tire - a set of PSS in Z06 size, and a set of Pilot Sport Cup RUNFLATS in ZR1 size for a set of ZR1 wheels I will run on the Z06. I haven't run the PS Cups yet, but will at VIR the end of June.

I got confused about which ones were runflats and which were not!

Sorry about the confusion, but if the PSS were available in a runflat I would definitely get them rather than the non-rf.

Let me go up and edit my original post!
