Thanks for your well thought out response. I've understood the dimensions you speak of for decades.... so I'm good on that end. I'm getting about 40-45K miles on the tires and this has been w/o rotation, so this should hopefully not be the issue, although the primary reason (not the only one of course) coupe owners chew through tires as they do is not due to not being able to rotate them but due to their driving habits. Do you have any ideas about tire size though, I'd like to hear your thoughts on this. Will 235/55's fit in the back w/o sticking out or rubbing?Sentientbydesign wrote:I think I need to do a tire size write up for you guys.
Let's take this arbitrary size for an example:
225/40/19
The first number (225) is the width of the tread in mm (divide by 10 for centimeters and divide by 2.54 for inches)
The second number is called the aspect ratio. It is the height expressed as a percentage of the width. So in this case 40% of 225 = 90mm
The last number is the inner diameter of the tire (rim size). You will some times see letter next to the rim size. These denote tire type (R for radial) and speed rating. (Z, Y, W...etc).
I DO NOT suggest you go staggered on your Sedan. We coupe owners have to deal with short lived tires all of the time because we can't rotate our tires. Why would you put yourself in that perdictament?
Thanks... this is what I was looking for. My real issue is to maximize height and not width per se. Adding a taller tire will, of course, reduce rotations per mile (since speed and power mean little to me), which may increase mpg. In all of my cars I've over-sized. In my Volvo 240 sedan (1992) I went from the standard 185/70's to 225/70,s- 4 sizes larger. I gained about 1-2mpg and lost about 20hp, which is not good for a car with <120hp to begin with. Lesson learned. Good info, again, thanks and also, thanks to the other folks who answered. If there's more info, please post it so I can read it.Sentientbydesign wrote:I had 17x7 on my I30 and 225s fit perfectly. The extra .4" in width of a 235 isn't going to put you over the edge.
The real problem with us coupe owners and our tires is three fold. We can't rotate them, there aren't many options for higher treadwear tires, and we sit lower than you do, so our front camber is always against us (except in turns!!!).
Tirerack, mentions an optional tire size of 235/50/17. The height difference is 1/20th of a inch (your tread varies more than that).
I would go with those all the way around!!!
I don't think you can put 245 or 275 on a 7" rim...tollboothwilley wrote:This is a topic that has surfaced a lot in the past few months and i'm sure will come up again...
I believe 245 is the largest you can on the front (without problems) and 275 in the rear.
