Good Morning DA,

Haven't been around in a while, but I'm about to buy 4 new tires for my 2010 accord coupe and was wondering what your guys take is on this..

Stock tire size is 225/50-17, I was wondering if putting 225/45-17 on the car would have any major negative effect or if the difference is so minor that it wouldn't be noticeable..

I like the look of less tire, I'm thinking in turn would also make the vehicle appear a bit lower and handle slightly better, maybe a little less "squishyness"..

I used to have Dunlop Signature II on my previous accord and really liked them, although this time around I will be going with the Dunlop SP Signature Sports.. Seems like a good all-season tire..

The handling will be tighter because of less sidewall. I can't speak to how noticeable it will be. The cons are your speedometer will read 3.7% lower and skew your odometer a little.

well the steering will be more responsive as turn in will be sharper and steer quicker due to less sidewall flex. It will also ride a little harsher due to the thinner sidewall with less cushion though not as bad as run flats in my experience .

Do you think that the extra .44" of wheel gap will be very noticeable? I plan on putting a set of springs on in the spring :lmao: so it would only be "monster truck" status for a few months..

Anybody have any pictures of their stock suspensions with a 225/45 instead of a 50?

I am going to be pulling the trigger on the tires by the end of the week so any feedback is appreciated..

Actually a better choice might be 235/45-17 or 245/45-17 presuming your wheels are wide enough to support them. It really kind of depends on what you're looking for by changing tire size.

They are the OEM Factory wheels that come on the 2010 LX-S Coupe. I think they are 17 x 7.5...

I'm kind of a dummy when it comes to tire sizing, will 235 fit on these?

I am looking for a little better performance-wise than the stock size without losing much of the look (don't want to have huge wheel gap)

The way you find that out is to go to an online seller like Discount Tire or Tire Rack and look up the tire size you're interested in. Then choose perhaps the tires you are planning to buy or any representative tire and look at the specifications listed for the tires. They normally list a recommended rim width range. You'll also find the rest of the specifications (like section width) for the tires you're considering that you may find interesting.

Gotcha, thanks for the advice ypsibird..

According to tire rack, the 235 will fit which is what I am probably leaning toward.. BUT.....

Do you think the tire's sidewall will bulge past the rim and look wierd?

Try to snag a used set of the 08-09 accord coupe 18s (with tires). That way you'll have less of a tire wall but still have the correct overall diameter which will keep your speedo correct. Also they are WAY nicer than the factory 17s.

That's probably a good idea. But going to the 235/45-18 coupe size won't necessarily keep the speedo correct. And it certainly is logical to think that it should. But at 60 mph with the 235/45-17 he'll be going 58.77 mph and with the 234/45-18 he'll be going 61.09 mph compared to his stock size.
