Tire help PLEASE!!! Do I need XL? Pirelli or Bridgestone?
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.

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).

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

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?
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.

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.




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...

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.




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 ?
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!).
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.
