New Tires - A Discovery

My tires are now down to a few 32nds before the wear bars and I was looking for new ones. The door says 235/45-18 and I have always assumed that was what was on my car. Today I was looking to see how old the tires were and finally actually read the sidewall. The previous owner put 225/45-18 tires on it! No wonder my speedo was a 2% off! I was this close -><- to buying 245/45-18 tires to get the speedo error closer.
I've checked the tread, the pressure and they need to run higher than the rated pressure to wear properly, which makes since if you stretch a smaller tire across a wide rim.
I'm glad I looked once in the year I've owned it to be sure.

I've never had 235s on my car. It came with the 225s so I can't say. They are not that much taller but a bit taller, about another .3" taller than the stock or 1.33% oversized. So, at 60MPH indicated, they would show 59MPH if 235s were correct already.

I decided to go with one size up and chose the Pirelli Cinturato P7 Plus All Season in 245/45R18 100V with a 70,000 mile warranty. I bought the tires from Discount Tires. I am very pleased with the tires. I highly recommend them... I seriously doubt you would notice any 'real' difference between 225, 235 or 245 widths when street driving. I personally wanted the 245 width to increase the footprint a little and increase the sidewall a tiny smidgen, and I think the 245 looks better.

I have a set of the Cinturato P7 Plus P235/40R19s right now.... I am very "conflicted" about these tires. They are noisy as hell compared to the Michelin MXM4s the car came with (although not snow tire noisy, but the difference is audible... on the flip side, the tread life is incredible and the rain handling is also incredible. Next week I am getting Michelin PS4S and a new set of wheels and the Cinturatos and my banged up original wheels will be sidelined for Nov-Mar intermittent winter use....
Of course, mileage varies. And what I experienced with one size of the tire might be nonexistant in another, so grain of salt and all that...

bclexus: What's you opinion on grand touring versus performance tires?
I always had grand tourings on my Camry, and they were great: quiet and comfortable, adequate in poor weather, but I never threw it around either.
I've always put performance all seasons on my GSs, never really thought about options. I'm not driving aggressively these days, once in a while maybe.

I used to have the Continental DWS 07, highly rated in the High performance category and my current Cinturato P7 Plus All Season Plus rides better. Unless your tracking the car high performance category is unnecessary.

The only other thing I can think of is that there is something wrong with my wheels which in turn makes the tires noisier, but I can't think of that would be. I had them road force balanced which got most of the vibration
out... The noise is especially prominent at speeds above 50-60 or so. Like if you drive my car at 80, you "know you're going 80 mph". With the MXM4s at 80, the car was so quiet it was pretty crazy...

If the car was tracked...or if it was a high-performance collector car that was driven only on pretty days or to car shows, then sure - put performance tires on it.
