Both great points fellas. I am starting to lean towards the Pirellis now because of the Moe factor and worries that the Michelin's may wear quickly too. It helped that in other posts some people seemed to be satisfied with those Pirellis so I figured they would at least be better than the Hankook'sthat I have as well.

As for the load, the Pirellis are a 100 XL tire a d the Michelins are 96 which I now know would cover my load. It looks like my car GWR was around 5250 I think and the 96 should cover about 6200 lbs when I finally figured that out last night, lol.

As for cost a local tire store has the Michelins for $1528 installed and the Pirellis are at the dealer for about $1400 installed. I am getting a little deal at the dealership because right now they have a buy 3 tires get one free sale.

Great choice! I've alternated between Continental, Pirelli and Michelin since my first car in 1959. A few years ago I abandoned Michelin due to excessive wear on 3 successive sets of Pilot Sport a/s 3 (2 sets free from Michelin due to premature wear @ 8k, 10k & 11k miles). Lately I've bought Pirelli P7 or P Zero tires depending on the car.

Great, that helps me feel better about my choice too. It's amazing that the Michelins had that much premature wear that they had to send you two new sets. Wow!

The Michelin pilot sport is a high performance tire, it will wear faster, the Primacy I have on my wife’s car has about 25,000 miles and it still have about half of it tread life left. The Michelin tires will ride stiffer than the P7 from my experience, the Conti is the most comfortable of the 3.

Just got the Costco flyer and their Michelin sale starts April 12th. I typically go with them because you get free balancing, road hazard, flat repair and rotation as part of the purchase and most other places you have to pay separately for that. Probably worth it for the 5 year road hazard alone.

Thanks for the word!!

Lots of good feedback from drivers on this thread. Thanks!

I ended up getting my Pirellis put on yesterday. So far so good. They don't feel drastically different than my Hankooks, but they are definitely more responsive. Nice so far.

I mentioned earlier that I have the Pirellis as well. Can you share your thought on road noise on yours? I was surprised at how loud mine were - I had the radio off debugging BT stuff and I though it was pretty bad.

You may need to check again after 500 or so miles as tires have a coating that needs to wear off to get an accurate feel for how they perform (for all areas, traction, responsiveness, comfort, noise etc).

Courthaven

Well it was a little noisier than I expected, but I was primarily on backroads for my driving yesterday. Once I got close to home I realized that they inflated my new tires to 40/41 psi (which settled down to about 38/39 today. I lowered them all to 34 and then I will try them out again and I hope to hear a little improvement.

After the coating wears off are you thinking that the tires will get better or worse?

ddeliber

It depends on what you are comparing but mostly better, for road noise it could get a little worse depending on weather, temp and road type. To be honest though, I don't really know, I just know it will change.

Courthaven

Jeez, well I hope it's for the better. I may find a reason to take these new tires on the highway today and see how they perform.

I never had road noise from my tires. My michelins are even quieter then my old runflats over bumps and have 0 road noise. Even the run flat Goodyear Eagle sports had no road noise. No brainer but have to ask, you had the alignment done when they put on the tires im assuming right?

ddeliber

Road noise is category that is compared for all tires. In fact there is a whole science behind developing quieter tires while minimizing the negative affects on other performance categories. Some do it better than others. There is a lot of testing/reviews out there for this.
Tire rack does a pretty good job but given the fact that they are selling tires they tend to "de-emphasize" their negative reviews so getting as much independent information is a good thing if you care about such things. Since TR is a commonly known source take a look here: https://www.tirerack.com/tires/tests...y.jsp?ttid=187 for one set of test results, and here for customer reviews: https://www.tirerack.com/tires/surve...dClar=#runflat

My comments earlier were because I noticed the noise with the Cinturatos that came with my car. I haven't really noticed this in the past so I looked it up. From what I can tell this model tire performs a bit worse than the competition and I was curious if anyone else noticed this. It bothers me so I am probably not going to use them in the future. It is not that they are screamingly loud or anything, they are just not very good in this area. Many people don't care much unless it is really bad - ever drive in a Jeep Wrangler?

I have been using the Michelin Pilot Sport A/S tires for the past 20 years, across multiple cars……now the Michelin Pilot Sport A/S is in its 4th iteration. I have always found them to be a great balance of ride comfort, excellent performance in the dry, wet and light snow, while lasting around 50,000 miles. For an Ultra-high performance A/S tire, I am perfectly fine with around 50,000 miles of tire-life. And the Michelins, unlike some other ultr-high-performance tires, maintains its performance throughout its tread-life, than having great performance when starting out, but then degrading once the miles start adding up, despite the presence of adequate tread.

To the OP’s question, if the original equipment was “XL” rated, I would get an XL rated replacement tire. Not just check the GVWR and go with the lowest possible tire spec that meets it. In my case, the All-Terrain came with XL rated run-flats, and I replaced them with XL-rated Michelin Pilot Sport A/S in the same size.

Courthaven

So now that I have driven on these Pirellis for a couple hundred miles I am pretty pleased with them considering they're runflats. I definitely feel like they are riding better than my Hankooks that the factory put on and the noise isn't too bad.

I have had tires that have a low pitch roar and I don't like that, but if anything the noise that I hear with these is fairly mild and could even be the sound of just the car moving on the highway. It's more of a higher pitched swishing through the wind sound if I were to describe it. It isn't too bad though especially when the radio is on.

MJG

I agree 100 percent. I hate driving in my Mercedes E450 with people and have to raise my voice to talk over bad road surface areas. Mercedes to me always should be soft and quiet plush ride.

MJG

I have Perellis on my E450 Sedan and they do ride noisy over the ground. My next tires I want to have a 9 plus score on road noise and comfort. I really hate the loud road noise. I never had that with a car before. Although I also have the Acoustic Comfort Package so it is VERY quiet in the car. So who knows, maybe with so much of the white noise canceled out, now I can hear it more.

MJG

I was curious about XL too. Question, so you also mention you went from RF to non RF with the Michelin Pilot sport... did you notice a difference in road noise or softness?

ua549

I replaced Michelin RF tires with Pirelli Cintuato non-RF tires and couldn't be happier. The ride, handling and sound is much better. Over the years I've compared and purchased several different tires including Michelin, Pirelli, Continental and Goodyear tires. Overall I've found the Pirelli tires are superior for my driving needs. If I had to rank the brands, Michelin would be in last place due to very poor tire wear - 8k miles replaced free by Michelin. Continental tires are a very close second to Pirelli. Finally, one must be careful about where each tire is produced. The US and Mexico manufactured tires are not on par with the same model tire manufactured in the EU.

can someone explain why my car has different tires ?

My diesel HYBRID has

FRONT 245 / 45R18 / 100Y / GOODYEAR EAGLE F1
REAR 275 / 40R18 / 103Y / GOODYEAR EAGLE F1

is this due to the weight maybe, since i have a huge battery in the back?

It's not that 'i m passionate about tires, but the problem is that i can not rotate them...

streborx

Car manufacturers do this for who knows why. They probably think some customers will think this is cool, rather than being a huge problem. At least your wheels are 18" and tire selection in this size is good.
My BMW came equipped with 275/40R22 on the front and 315/35R22 on the rear, performance (summer) run-flats. I replaced them with a new set of 20" wheels and 4 Michelin CrossClimate2's in 275/50R20. I can run the Michelins year-round and rotate them. When I sell/trade, I'll put the original set back on, and offer the other set to the buyer.

Egonvdv

cheers
i can't even spot the difference between them, so it's not an aesthetic thing
if in the future i would choose 4 of the same, which type should i take ?

You can compare the two tire sizes on https://tiresize.com/comparison/. This will show you that your existing tire diameters are the same, but the rear tires are 1.2" wider than the front.

If you want to "square-up", the simple solution is to go with the front tire size 245/45R18 on all four. Front tire width is usually the limiting factor because of potential interference when turning -- too wide and the tire will rub. Your rear wheels might be a half to full inch wider than the front wheels, so you need to make sure that the tire you buy in the 245 width will fit the wider wheel that currently has the 275 on it. Usually tires can accommodate a range of wheel widths.

If you deviate from the the 245/45 profile, the tire diameter will change and this will affect your speedometer and odometer. A small change of a percent or two isn't a problem, but if you go more than 3%, you might want a dealer to reprogram the car accordingly. Depending on your existing wheels, you might need to do this. For example, a 255/45R18 might be a size that will fit on all four wheel widths, but your diameter will change by +1.1%. The 255 is only 10mm wider than than the 245 so front tire interference is not likely.

Best solution is to talk to your tire dealer. Tell him you want to square-up, and he can tell you what size will fit and what brands are available (Michelin, of course!).

I would buy tires with at least a 103Y rating. Load index 103 indicates an 875 kg load per tire. Load index 100 indicates 800 kg load per tire.
There are many tires of either size with the 103 rating.
275/40R18 will give you somewhat better handling, but I doubt if you would notice the difference.
